Monetary policy in liberalized financial markets: the Mexican case*
Authors: Capraro Santiago , Panico Carlo
Published: January 2021

The paper examines the behavior of monetary policy and the institutional organization of economic policy in Mexico during the years of financial liberalization and the outgrowth of the financial industry. It argues that these policies have favored monetary and financial stability at the cost of reducing investment and negatively affecting the strength of the productive structure and the international competitiveness of the economy. The paper argues that such negative results, with the passage of time, increase the odds that current monetary policy will become unable to pursue monetary and financial stability. Unlike other outstanding critical literature, the emphasis of our evaluation regarding current policy's negative consequences is on the reduction of public investment that the institutional organization of economic policy has produced, instead of the overvaluation of the real exchange rate. As a final point, the paper discusses how institutional organization can be reformed to avoid further weakening of the productive structure and international competitiveness of the Mexican economy.
An analysis on E-Business in Manufacturing Logistics
Authors: Emadi Jain
Published: January 2021

In manufacturing logistics, the selected software products and organizational processes provide reliable and suitable applications in Small and Medium-Sized Enterprises (SMEs). Nonetheless, because of the sudden change and enhancement of Information Systems (IS), some potential remedies are outdated and have to be reviewed and replaced with modern IS. As such, the Enterprise Resource Planning (ERP) frameworks can be considered as well. This paper evaluates E-Business in manufacturing logistics while reflecting advanced Supply Chain management (SCM) frameworks for SMEs, data mining and cloud computing. After evaluating the elements and issues of the change management in enterprises, this contribution focusses on Dynamic AX and Systeme Anwendungen Produkte (SAP) which is the ERP systems with reference to manufacturing logistics. In this business segment, the requirement for long-lasting and supporting remedies with technological application is fundamental. Currently, there is just a slight variation in technological application, but there is a significant change in how business flows in SMEs.

The paper offers a critical review of recently published studies of the factors contributing to a successful transition to indepemdent life by the young in foster care. The review includes research conducted in various cultural contexts, such as the USA, Germany, Norway, Korea, Israel, as well as our own country. Our aim has been to describe the considerable achievents in this field, and point out the importance of those results which have been confirmed in more than a single research – specifically, the crucial role of social support in a successful passage to independent life. In addition to being established as culturally universal, this result has been obtained both in the studies concerned with successful transitions, and those focusing on the difficulties faced by the young people leaving foster care. The review also includes research which adresses the questions of what do the capability and readiness of adolescents to build and rely on social support depend on. In the paper the shortcomings and omissions of the studies examined are also considered and possible perspectives for further research into the complex problems related to leaving foster care are suggested, so that the results of such scientific invetigations might be of greater service in the planning and providing of actual interventions.

В настоящей статье рассматривается возмущения дифференциального уравнениявторого порядка спектральной задачи с нагруженным слагаемым, содержащий значениеискомой функции в точке нуль, с регулярными, но неусиленно регулярными краевымиусловиями. Исследуется вопрос базисности систем собственных и присоединенных функций(СиПФ) нагруженного оператора кратного дифференцирования. Известно, что системасобственных функций оператора, заданного формально самосопряженнымдифференциальным выражением, с произвольными самосопряженными краевымиусловиями, обеспечивающими дискретный спектр, образует ортономированный базис.Наряду с этим, известно, что в случае несамосопряженных обыкновенныхдифференциальных операторов на базисность систем корневых функций, помимо краевыхусловий, могут влиять также значения коэффициентов дифференциального оператора. Приэтом базисные свойства корневых функций могут изменяться даже при сколь угодном маломизменении значений коэффициентов. Такой факт был отмечен в работе В.А. Ильина. Внастоящей работе построен характеристический определитель рассматриваемойспектральной задачи, который является целой аналитической функцией. Доказана теорема онеустойчивости свойств базисности корневых векторов и построен сопряженный оператор,который является задачей Самарского-Ионкина с интегральным возмущением.

В работе рассматривается нелинейная интегро-дифференциальная система сингулярновозмущенных уравнений. Обсуждается вопрос о спектре ее оператора, который не совпадаетсо спектром ее предельного оператора и включает в себя дополнительно тождественнонулевую точку. В случае линейных систем это различие не играет особой роли, так какрегуляризация и построение пространства решений соответствующих итерационных задачреализуются по ненулевым точкам спектра. В случае нелинейных задач тождественнонулевая точка спектра играет существенную роль при конструировании пространстварешений в резонансном и нерезонансном случаях (см. ниже), поэтому в большинстве работпо методу регуляризации в нелинейных задачах обычно рассматривается лишьнерезонансный случай.

El activismo sindical, como toda actividad humana que no puede hacerse con total independencia de las otras que realiza el mismo sujeto, tendrá influencias en el desenvolvimiento del profesorado en su accionar profesional. El presente estudio provee una aproximación, por un lado, a las diferencias en materia de activismo sindical que presenta el personal docente de dos centros educativos de gestiones de naturalezas distintas, a saber, uno de gestión pública, otro de gestión semiprivada; y, por el otro lado, se acerca a los sentidos que ambos grupos dan a su pertenencia al sindicato, en lo que respecta tanto a su autopercepción en cuanto miembros activos del gremio, como a las reflexiones que se realizan en torno al sindicato, su función social y su deber frente a la educación. Se trabajó con una muestra no probabilística escogida a conveniencia de dos centros educativos con docentes miembros del sindicato que voluntariamente participaron de la investigación; se les aplicó un instrumento que recoge la propia percepción de su nivel de activismo, así como su activismo real y sus reflexiones en torno al papel de su gremio. Se halló un mayor nivel de activismo en los docentes del centro público que en los del centro de gestión semiprivada; además, la autopercepción de los participantes en materia de activismo sindical resultó ser coherente con su actividad y apoyo al sindicato, y se evidencia una crítica por parte de los participantes que, en términos generales, entienden que su gremio tiene oportunidades de mejora en lo que atañe a su contribución con un aumento de la calidad educativa.

THE TECHNIQUES OF SELECTION AND AESTHETICS OF ECART IN THE NOBLE QUR’AN - SEMANTIC STUDY
Authors:   Iraqia University, AL–ZUBAIDY AHMED
Published: January 2021

The research touched upon that the Qur’an is an intentional rhetoric expression. That is, every word and every letter in it has an intentional position, and that the word in it is like an organ in the human body and it performs its function when it is in its position, and if it is removed to another location. Body changes! Therefore, we find that it has been selected with extreme precision and wisdom, so that no other words or expressions else can take the place in which it is located. No matter how many lexicons, language books, or exegesis gather a number - less or more - of alternative, approximate synonyms, and that the alternative equivalent has the same meaning still impossible for these alternatives to play and reflect the same sense and aesthetics of the original Quranic words. The words were determined according to their meanings, and every type of those words that are included in the context of speech has its own role. The Quran's words are worthy and more deserving of use, called for the finite accuracy of the expression and the extreme precision to the extent that it is impossible to replace its original words with proposal alternatives that may distort meanings among the possibilities, and the intentions and purposes are lost in the aberration of doubt and camouflage This is due to the subtle differences between the words in their connotations.
AES Enhanced by Output Feedback Block Mode Operation
Authors: Hani Asaad A.
Published: January 2021

There is a great research in the field of data security these days. Storing information digitally in the cloud and transferring it over the internet proposes risks of disclosure and unauthorized access; thus, users, organizations, and businesses are adapting new technology and methods to protect their data from breaches. In this paper, we introduce a method to provide higher security for data transferred over the internet, or information based in the cloud. The introduced method for the most part depends on the Advanced Encryption Standard (AES) algorithm, which is currently the standard for secret key encryption. A standardized version of the algorithm was used by The Federal Information Processing Standard 197 called Rijndael for the AES. The AES algorithm processes data through a combination of exclusive-OR operations (XOR), octet substitution with an S-box, row and column rotations, and MixColumn operations. The fact that the algorithm could be easily implemented and run on a regular computer in a reasonable amount of time made it highly favorable and successful. In this paper, the proposed method provides a new dimension of security to the AES algorithm by securing the key itself such that even when the key is disclosed; the text cannot be deciphered. This is done by enciphering the key using Output Feedback Block Mode Operation. This introduces a new level of security to the key in a way, in which deciphering the data requires prior knowledge of the key and the algorithm used to encipher the key for the purpose of deciphering the transferred text.
Shedding light on pre-Columbian crania collections through state-of-the-art 3D scanning techniques

Published: January 2021

During the 19th and 20th centuries, numerous museums, scientific societies, and royal academies were founded in Europe and America. In this scenario, the Anthropological Museum Montané was founded in Havana, Cuba. Its collection has grown over the years, thanks to researchers, antiquarians, and amateurs. Since its foundation, the Museum Montané has become an essential institution for anthropological and archaeological research in the region. Nowadays, the Museum Montané, like other museums in developing countries, faces a challenge in the introduction of state-of-the-art technologies to digitizing exhibits and the creation of innovative projects to attract visitors. The current possibilities of virtualization of cultural heritage using digital technologies have a favorable impact on the preservation, access, and management of museum collections. The use of three-dimensional (3D) models fosters engagement with visitors, stimulates new forms of learning, and revalorizes the exhibits. In the current study, we use a hand-held structured light scanner to create 3D reality-based models of pre-Columbian crania from the Caribbean and South American collection of the Anthropological Museum Montané. The resulting 3D models were used for producing 3D printing replicas and animated videos. The 3D resources derived will encourage new knowledge through research, and provide broader access to these pre-Columbian crania collection through learning and outreach activities. The significance of digitizing these specimens goes beyond the creation of 3D models. It means protecting these fragile and valuable collections for future generations. The methodology and results reported here can be used in other museums with similar collections to digitally document, study, protect, and disseminate the archaeological heritage. Going forward, we seek to continue exploring the application of novel methods and digital techniques to the study of the pre-Columbian crania collections in Latin American and the Caribbean area.

Highlights:

A hand-held structured light scanner was used to acquire 3D reality-based models of pre-Columbian crania. The 3D models resulting were used for 3D printing replicas and 3D animations.

This study provides unprecedented 3D reconstructions of pre-Columbian crania in the Caribbean area, and new 3D reconstructions of artificially deformed crania from South America.

The 3D resources created will encourage new knowledge through research, and provide broader access to these pre-Columbian crania collection through learning and outreach activities.
Interactive virtual representation of the disappeared convent of El Carmen (Logroño) generated from a paper craft model
Authors: Rodríguez-Miranda Alvaro , Valle Melón José M. , Korro Bañuelos Jaione , Elorriaga Aguirre Garbiñe
Published: January 2021

The concept of mock-up, which share with the drawing the expressive synthesis for the analysis of the architectural form and evolution, is an invaluable asset for the preservation of the heritage. To mark the 175th anniversary of the Práxedes Mateo Sagasta’s secondary school of Logroño (Spain), an exhibition about the history of the institution was organized at the premises of La Rioja Library. The current school building became operational in 1900 and was built on the former site of a Carmelite convent. In fact, the convent rooms were the first location for the school, after the expropriations of religious communities during the mid-19th century. For the benefit of the aforementioned exhibition, it was considered interesting to generate a three-dimensional (3D) virtual reconstruction of the convent buildings to show how it would have looked. However, the lack of sufficient contemporary graphic information was a challenge, so it was decided that an efficient solution would be to generate the virtual reconstruction from a paper craft model, which had been created by the librarian of the secondary school as a result of his research on this matter. This text describes the 3D modelling of that cut-out element by means of monoscopic photogrammetry (perspective drawing) and the use of non-realistic rendering based on the appearance of the paper mock-up (and not trying to recreate the real image of the buildings) so as to provide a suggestive view of the convent and create interactive exhibition items. Moreover, the text deals with the long-term preservation and the improvement of the re-use of the 3D models. The former by resorting to institutional repositories —from which users can download the full detailed versions— and the latter employing versions able to be visualized in 3D warehouses (such as Sketchfab) and augmented reality (AR) applications.

Highlights:

A significant part of the architectural heritage is represented by mock-ups of different materials (paper, wood, metal and so on).

Virtual modelling and augmented reality (AR) can be appropriate tools for materializing, recovering and disseminating scale models to the public.

Techniques for geometric documentation and visual representation need to be adapted in order to tackle the peculiar features of these elements (size, materials, fragility, etc.).

Published: January 2021

Indonesia's energy diplomacy to Algeria was one of the efforts of the Indonesian government to maintain national energy security. Considering that the production produced from domestic sources has not been able to meet national energy needs, the Indonesian government tried to find exploration and production fields outside of Indonesia's territory. In effort to find fields that can be explored, the Indonesian government took a certain approach of diplomacy and negotiation with other governments. For that reason, this article aims to raise this topic is to find out what kind of strategy or approach was being carried out by the Indonesian government in conducting energy diplomacy in Algeria. To examine this topic, researcher used the concept of a grand strategy related to energy, energy diplomacy, and the concept of Indonesia's normative power. Researcher tried to prove that Indonesia's energy diplomacy strategy in acquiring oil fields in Algeria was done through strategy and decision making, which in the strategy there was a political approach and in the decision-making there was a business approach. The two approaches should synergize and complement each other, therefore consolidation between the two approaches was needed. Researchers using qualitative methods with analytical techniques using process tracing. One of the conclusions of this research is that the role of the Indonesian government was needed in supporting the acquisition of oil fields in Algeria.

Aim: Beta-thalassemia (β-thalassemia) major is one of the most common inherited genetic blood disorders and is characterized by many systemic manifestations and skeletal problems. Children with β-thalassemia have a high caries index and must receive proper dental treatment to achieve better oral health. The aim of study is to compare two types of vital pulp therapies in children with β-thalassemia major. Methods: Sixty-five children with β-thalassemia major having carious primary molars were selected from Ain Shams University and the Hereditary Blood Disorders Clinic at the National Research Centre to be treated at Pediatric Dentistry, Department, Faculty of Dentisrtry, Ain Shams University . Patients received one of both types of vital pulp therapies: mineral trioxide aggregate (MTA) pulpotomy and indirect pulp capping. The children were divided into two groups as follow: Group I (n=30) received MTA pulpotomy and Group II (n=35) received indirect pulp capping using high viscosity glass ionomer cement. Clinical and radiographic follow-ups were done at the baseline, six months, and after one year. Patient preferences for types of vital pulp therapies were evaluated at the end of treatment. Comparison of the groups with qualitative data was done using Chi-square test. Comparison of the groups with quantitative data and a parametric distribution was done using an independent t-test at significance level 0.05. Results: The findings revealed success rates of 90% in Group I and 100% in Group II. There was 10% clinical and radiographic failure in Group I and 0% in Group II but the difference between the two groups when compared to each other was statistically not significant (p= 0.055). Conclusions: Both types of vital pulp therapies showed high success rates in children with β-thalassemia major and thus can be used safely in these patients. However, minimally invasive types of dental treatment may be preferred in children with β-thalassemia major as indirect pulp capping for being less invasive and requires less effort, fatigue and time.

Published: January 2021

Fear Of Missing Out (FOMO) is a growing problem that arouses interest from scientists, media and recipients. Therefore, finding a universal way to calculate the scale of the phenomenon can not only become a common tool for estimating the extent of FOMO occurrence in any country, but also can be considered for managing this phenomenon. The article presents the results of measuring the FOMO scale in Poland in 2018. The project applied a Computer Assisted Web Interview survey of the representative sample (N=1060) of Poland’s internet users aged 15 years plus. Three groups of ‘FOMO level’ characteristics were determined (age was the most influential variable). The original method of recalculation of the FOMO scale results from figures to percentage data was developed in order to present the FOMO scale index. The FOMO items showed good internal consistency and reliability Cronbach’s α = .89, thus complementing previous international studies.
Traditional and Online Media: Relationship between Media Preference, Credibility Perceptions , Predispositions, and European Identity
Authors: Ejaz Waqas
Published: January 2021

The present study investigates the relationship between people’s preference of either traditional or online media for news consumption, credibility evaluation of media and their sense of European identity. In order to do so, the study draws on the Social Identity Theory and the findings of social psychologists which situate European identity a concept that corresponds to an individuals’ subjective assignment to a collective and their affective and evaluative attachment to it. The analysis based on Eurobarometer survey data reveals that preferences of both online and traditional media for political news positively affects European identity. However, such an effect is dependent on people’s pre-existing attitudes towards the EU and if they perceive the media to be neutral and credible.

Abstract. The knowledge of the dynamics of sub-3 nm particles in the
atmosphere is crucial for our understanding of the first steps of atmospheric new particle formation. Therefore, accurate and stable long-term measurements of the smallest atmospheric particles are needed. In this study, we analyzed over 5 years of particle concentrations in size
classes 1.1–1.7 and 1.7–2.5 nm obtained with the particle size
magnifier (PSM) and 3 years of precursor vapor concentrations measured
with the chemical ionization atmospheric pressure interface time-of-flight
mass spectrometer (CI-APi-ToF) at the SMEAR II station in Hyytiälä,
Finland. The results show that there are significant seasonal differences in median concentrations of sub-3 nm particles, but the two size classes behave partly differently. The 1.1–1.7 nm particle concentrations are highest in summer, while the 1.7–2.5 nm particle concentrations are highest in springtime. The 1.7–2.5 nm particles exhibit a daytime maximum in all seasons, while the 1.1–1.7 nm particles have an additional evening maximum during spring and summer. Aerosol precursor vapors have notable diurnal and seasonal differences as well. Sulfuric acid and highly oxygenated organic molecule (HOM) monomer concentrations have clear daytime maxima, while HOM dimers have their maxima during the night. HOM concentrations for both monomers and dimers are the highest during summer and the lowest during winter following the biogenic activity in the surrounding forest. Sulfuric acid concentrations are the highest during spring and summer, with autumn and winter concentrations being 2 to 3 times lower. A correlation analysis between the sub-3 nm concentrations and aerosol precursor vapor concentrations indicates that both HOMs (particularly their dimers) and sulfuric acid play a significant role in new particle formation in the boreal forest. Our analysis also suggests that there might be seasonal differences in new particle formation pathways that need to be investigated further.
The interpretation of temperature and salinity variables in numerical
ocean model output, and the calculation of heat fluxes and heat content

Abstract. The 2010 international thermodynamic equation of seawater, TEOS-10, defined the enthalpy and entropy of seawater, thus enabling the global ocean heat content to be calculated as the volume integral of the product of in situ density, ρ, and potential enthalpy, h0 (with reference sea pressure of 0 dbar). In terms of Conservative Temperature, Θ, ocean heat content is the volume integral of ρcp0Θ, where cp0 is a constant isobaric heat capacity. However, several ocean models in CMIP6 (as well as all of those in previous Coupled Model Intercomparison Project phases, such as CMIP5) have not been converted from EOS-80 (Equation of State - 1980) to TEOS-10, so the question arises of how the salinity and temperature variables in these models should be interpreted. In this article we address how heat content, surface heat fluxes and the meridional heat transport are best calculated in these models, and also how these quantities should be compared with the corresponding quantities calculated from observations. We conclude that even though a model uses the EOS-80 equation of state which expects potential temperature as its input temperature, the most appropriate interpretation of the model's temperature variable is actually Conservative Temperature. This interpretation is needed to ensure that the air-sea heat flux that leaves/arrives-in the atmosphere is the same as that which arrives-in/leaves the ocean. We also show that the salinity variable carried by TEOS-10 based models is Preformed Salinity, while the prognostic salinity of EOS-80 based models is also proportional to Preformed Salinity. These interpretations of the salinity and temperature variables in ocean models are an update on the comprehensive Griffies et al. (2016) paper that discusses the interpretation of many aspects of coupled model runs.
Potential effects of cryogenic extraction biases on inferences drawn
from xylem water deuterium isotope ratios: case studies using stable
isotopes to infer plant water sources
Authors: Allen Scott T. , Kirchner James W.
Published: January 2021

Abstract. Recent studies have demonstrated that plant and soilwater extraction techniques can introduce biases and uncertainties in stable isotope analyses. Here we show how recently documented δ2H biases resulting from cryogenic vacuum distillation of water from xylem tissues may have influenced the conclusions of five previous studies, including ours, that have used δ2H to infer plant water sources. Cryogenic extraction biases that reduce xylem water δ2H will also introduce an artifactual evaporation signal in dual-isotope (δ2H vs. δ18O) analyses. Calculations that estimate the composition of the source precipitation of xylem waters by compensating for their apparent evaporation will amplify the bias in δ2H, and also introduce new biases in the δ18O of the inferred pre-evaporation source precipitation. Cryogenic extraction biases may substantially alter plant water source attributions if the spread in δ2H among the potential end members is relatively narrow. By contrast, if the spread in δ2H among the potential end members is relatively wide, the impact of cryogenic extraction biases will be less pronounced, and thus suggestions that these biases universally invalidate inferences drawn from plant water δ2H are unwarranted. Nonetheless, until reliable correction factors for cryogenic extraction biases become available, their potential impact should be considered in studies using xylem water isotopes.
Technical Note: Improved partial wavelet coherency for understanding scale-specific and localized bivariate relationships in geosciences
Authors: Hu Wei , Si Bing
Published: January 2021

Abstract. Bivariate wavelet coherency is a measure of correlation between two variables in the location–scale (spatial data) or time–frequency (time series) domain. It is particularly suited to geoscience, where relationships between multiple variables differ with locations (times) and/or scales (frequencies) because of the various processes involved. However, it is well-known that bivariate relationships can be misleading when both variables are dependent on other variables. Partial wavelet coherency (PWC) has been proposed to detect scale-specific and localized bivariate relationships by excluding the effects of other variables but is limited to one excluding variable and provides no phase information. We aim to develop a new PWC method that can deal with multiple excluding variables and provide phase information. Both stationary and non-stationary artificial datasets with the response variable being the sum of five cosine waves at 256 locations are used to test the method. The new method was also applied to a free water evaporation dataset. Our results verified the advantages of the new method in capturing phase information and dealing with multiple excluding variables. Where there is one excluding variable, the new PWC implementation produces higher and more accurate PWC values than the previously published PWC implementation that mistakenly considered bivariate real coherence rather than bivariate complex coherence. We suggest the PWC method is used to untangle scale-specific and localized bivariate relationships after removing the effects of other variables in geosciences. The PWC implementations were coded with Matlab and are freely accessible (https://figshare.com/s/bc97956f43fe5734c784, last access: 14 January 2021).
Ordering of trajectories reveals hierarchical finite-time coherent sets in Lagrangian particle data: detecting Agulhas rings in the South Atlantic Ocean
Authors: Wichmann David , Kehl Christian , Dijkstra Henk A. , van Sebille Erik
Published: January 2021

Abstract. The detection of finite-time coherent particle sets in Lagrangian trajectory data, using data-clustering techniques, is an active research field at the moment. Yet, the clustering methods mostly employed so far have been based on graph partitioning, which assigns each trajectory to a cluster, i.e. there is no concept of noisy, incoherent trajectories. This is problematic for applications in the ocean, where many small, coherent eddies are present in a large, mostly noisy fluid flow. Here, for the first time in this context, we use the density-based clustering algorithm of OPTICS (ordering points to identify the clustering structure; Ankerst et al., 1999) to detect finite-time coherent particle sets in Lagrangian trajectory data. Different from partition-based clustering methods, derived clustering results contain a concept of noise, such that not every trajectory needs to be part of a cluster. OPTICS also has a major advantage compared to the previously used density-based spatial clustering of applications with noise (DBSCAN) method, as it can detect clusters of varying density. The resulting clusters have an intrinsically hierarchical structure, which allows one to detect coherent trajectory sets at different spatial scales at once. We apply OPTICS directly to Lagrangian trajectory data in the Bickley jet model flow and successfully detect the expected vortices and the jet. The resulting clustering separates the vortices and the jet from background noise, with an imprint of the hierarchical clustering structure of coherent, small-scale vortices in a coherent, large-scale background flow. We then apply our method to a set of virtual trajectories released in the eastern South Atlantic Ocean in an eddying ocean model and successfully detect Agulhas rings. We illustrate the difference between our approach and partition-based k-means clustering using a 2D embedding of the trajectories derived from classical multidimensional scaling. We also show how OPTICS can be applied to the spectral embedding of a trajectory-based network to overcome the problems of k-means spectral clustering in detecting Agulhas rings.
Acceleration of Tropical Cyclones As a Proxy For Extratropical
Interactions: Synoptic-Scale Patterns and Long-Term Trends
Authors: Aiyyer Anantha , Wade Terrell
Published: January 2021

Abstract. It is well known that rapid changes in tropical cyclone motion occur during interaction with extratropical waves. While the translation speed has received much attention in the published literature, acceleration has not. Using a large data sample of Atlantic tropical cyclones, we formally examine the composite synoptic-scale patterns associated with tangential and curvature components of their acceleration. During periods of rapid tangential acceleration, the composite tropical cyclone moves poleward between an upstream trough and downstream ridge of a developing extratropical wavepacket. The two systems subsequently merge in a manner that is consistent with extratropical transition. During rapid curvature acceleration, a prominent downstream ridge promotes recurvature of the tropical cyclone. In contrast, during rapid tangential or curvature deceleration, a ridge is located directly poleward of the tropical cyclone. Locally, this arrangement takes the form of a cyclone-anticyclone vortex pair somewhat akin to a dipole block. On average, the tangential acceleration peaks 18 hours prior to extratropical transition while the curvature acceleration peaks at recurvature. These findings confirm that rapid acceleration of tropical cyclones is mediated by interaction with extratropical baroclinic waves. Furthermore, The tails of the distribution of acceleration and translation speed show a robust reduction over the past 5 decades. We speculate that these trends may reflect the poleward shift and weakening of extratropical Rossby waves.
