Heritage of Portuguese Influence as Erasure: Critical Perspectives on the Recreation of the Past in the Present
Authors: INÊS BELEZA BARREIROS
Published: July 2024

ABSTRACT: Several  attempts  have  been  made  to  define  and  catalogue  the  “heritage  of  Portuguese  influence,”  but  none  has  critically  addressed  the  politics  at  work  in  such  heritage. The colonial violence that effectively scattered this heritage across the world has often been erased and replaced by the exaltation of a Portuguese imperial past expressed  through  aestheticization.  This  paper  exposes  the  materiality  of  such  heritage  through discourse analysis, starting by unpacking one concrete example, theSete Maravilhas de Origem Portuguesa no Mundocompetition in 2009, and tracking down the conditions of possibility (when, how, and why) for this discourse practice to emerge in the Jornadas Luso-Brasileiras do Património (1984) and the Primeiro Congresso do Património Construído Luso no Mundo (1987) and to endure in such objects as História da arte portuguesa no mundo (1998–99) and Património de origem portuguesa no mundo(2010–11) as part of a visual economy that entails the spatial and temporal flow of images and discourses. This paper also examines the endurance of an imperial episteme that feeds on the idea of a supposed “Portuguese world” and gives form to its complex.
KEYWORDS: coloniality, imperial episteme, visuality, “Portuguese world” complex
RESUMO: Várias tentativas foram feitas para definir e catalogar “o património de influên-cia  portuguesa,”  mas  nenhuma  delas  abordou  criticamente  a  política  que  impregna  esse mesmo património. Frequentemente a violência colonial que, justamente, fez com que esse património esteja hoje espalhado pelo mundo inteiro é apagada em favor da exaltação  do  passado  imperial  português  expresso  sobretudo  através  da  estetização  deste  património.  Este  artigo  examina,  através  de  uma  análise  discursiva,  esta  materialidade  tomando  como  ponto  de  partida  o  concurso  das  Sete  Maravilhas  da  Origem  Portuguesa  no  Mundo  (2009)  e  rastreando  as  condições  de  possibilidade  (quando,  como e porquê) desta prática discursiva até às Jornadas Luso-Brasileiras do Património (1984) e ao Primeiro Congresso do Património Construído Luso no Mundo (1987), para igualmente analisar a sua permanência em objectos como a História da arte portuguesa no mundo (1999) e Património de origem portuguesa no mundo (2010) como parte de uma economia visual que pressupõe o fluxo espácio-temporal de imagens e discursos. Este artigo também aborda criticamente a sobrevivência de uma episteme imperial que se alimenta de um suposto “Mundo Português” e dá forma ao seu complexo.

As Veias Abertas da Afrodescendência: Herança Colonial e Contemporaneidade
Authors: IOLANDA ÉVORA  , INOCÊNCIA MATA
Published: July 2024

RESUMO: A partir de uma re³exão que percorre os elementos principais dos meandros das conceptualizações que caracterizam a Afrodescendência, o artigo ressalta a experiência actual dos afrodescendentes em Portugal, marcada pelas especifcidades dos modos de incorporação dos ex-colonizados no país e pelos esforços de delimitação da identidade nacional nas fronteiras da branquitude, mesmo perante pessoas cuja existência não permite mais duvidar de que há negros portugueses. Apontando para a relevância dos modos pelos quais os portugueses não-brancos (e afrodescendentes) buscam uma designação de/para si actualmente, ousando afastar-se (e/ou contrapor-se) à estigmatização de que são alvo, o artigo busca inventariar e questionar conceitos que são adoptados e vulgarizados em torno da Afrodescendência que, na actualidade, vão mais além do desvelamento da estigmatização, da presença e existência de afrodescendentes no espaço social português.

ABSTRACT: On the basis of a re³ection that identifes the main elements of the intricacies of conceptualizations that characterize Afrodescendence, the article highlights the current experience of Afro-descendants in Portugal, which is distinguished by the specifcities of the ways the ex-colonized are incorporated into the country and by the efforts of delimitating national identity in terms of whiteness, despite the presence of people whose existence leaves no room for doubt that there is a Black Portuguese population. Indicating the relevance of the ways in which non-white Portuguese (and Afrodescendants) seek a designation of/for themselves today, daring to distance themselves from (and/or counteract) the stigmatization that targets them, the article seeks to inventory and question concepts that are adopted and vulgarized around Afrodescendence that, at present, extend beyond the unveiling of stigmatization, the presence and existence of Afro-descendants in the Portuguese social space.

The Memorialization of Empire in Postcolonial Portugal: Identity Politics and the Commodification of History
Authors: ELSA PERALTA
Published: July 2024

ABSTRACT: The entire experience of modern imperialism has profoundly shaped European national identities in ways that continue to matter in postimperial times. This is also true of Portugal; as the first and the most enduring of the European colonial empires, its end did not erase the self-image of the country as an imperial nation. Although refashioned in a matter of style and content, major public representations of the nation’s collective identity remain anchored in the memory of empire. This official memory combines a strong emphasis on the period of the “Maritime Discoveries” with the represen-tation of Portugal as the pioneer of cultural dialogue on a global scale and of the Portuguese as “inventors” of the modern world. In this article, I will address some examples of the way in which Portugal’s imperial history has been memorialized to convey the country’s “brand image,” for the purposes of both identity politics and the tourism industry.
KEYWORDS: public  memory,  Portuguese  empire,  nationalism,  cosmopolitanism,  commodification
RESUMO: Toda a experiência do imperialismo moderno moldou profundamente as iden-tidades nacionais europeias de maneiras que continuam a ser importantes nos tempos pós-imperiais. Este também é o caso de Portugal: sendo o primeiro e o mais duradouro império  colonial  europeu,  o  seu  fim  não  apagou  a  auto-imagem  do  país  como  nação  imperial. Embora remodelada em termos de estilo e conteúdo, as principais representa-ções públicas da identidade coletiva da nação permanecem ancoradas na memória do império.  Esta  memória  oficial  combina  uma  forte  ênfase  no  período  das  “Descobertas  Marítimas” com a representação de Portugal como pioneiro do diálogo cultural à escala global e dos portugueses como “inventores” do mundo moderno. Neste artigo, aborda-rei alguns casos através dos quais a história imperial de Portugal foi memorializada para transmitir  uma  “imagem  de  marca”  de  Portugal,  tanto  para  as  políticas  da  identidade  quanto para a indústria do turismo.

Authors: Mani Paul , Maina Ben
Published: July 2024

This research investigates the factors influencing the adoption of electric vehicles (EVs) among public service vehicle operators in Kenya. The study employs a descriptive survey design, encompassing 212 public vehicle operators in the country. The primary objectives include assessing the impact of cost, infrastructure development, knowledge, and social-cultural factors on the adoption of EVs by public service vehicle operators in Kenya. The study conducted in-depth interviews and focus group discussions with a selected subset of participants to gain deeper insights into the qualitative aspects of the study. The study reveals that cost, infrastructure development, knowledge, and social-cultural factors collectively influence the adoption landscape. High upfront costs and operational expenses pose significant barriers, emphasizing the need for financial incentives and supportive policies to make EVs more economically viable. Infrastructure development, particularly the establishment of a robust charging network, is crucial to alleviate range anxiety and enhance the practicality of EVs. Knowledge gaps among operators highlight the importance of educational programs and training initiatives to enhance understanding and promote the benefits of electric vehicles. Social-cultural factors, such as attitudes and perceptions, also shape adoption patterns, emphasizing the need for awareness campaigns to address misconceptions. In conclusion, a comprehensive strategy involving financial incentives, infrastructure development, knowledge dissemination, and cultural sensitization is recommended to foster the widespread adoption of electric vehicles in Kenya's public service transportation sector
Development of an improvised convertible distillation apparatus for teaching and learning chemistry
Authors: Galiga Henley
Published: July 2024

Distillation is an important concept in chemistry as it involves separation techniques which are widely used in various industries. However, despite its significance, it is hardly understood and appreciated because it is rarely performed in laboratory experiments. Distillation requires expensive apparatus to conduct which most schools cannot afford. Hence, an improvised convertible distillation apparatus for simple, fractional and steam distillation was developed using common household and recyclable materials. Improvised measuring devices were also fabricated to determine the purity of the distillates. The performance of improvised apparatus was assessed and compared with the standard apparatus using real samples. The improvised apparatus, using fractional distillation set-up, produced 91.3% alcohol from alcoholic beverage while the simple/steam distillation setup, yielded distilled water from the salt-water sample and essential oil from pomelo (Citrus maxima) peel with percentage yield of 0.56%, respectively. The improvised apparatus for fractional distillation yielded a higher alcohol content (x̅=91.3%; 95%CI=91.0, 91.6) than the standard apparatus (x̅=85.7%; 95%CI=85.3, 86.1) while the efficiency of separation of the improvised apparatus for simple/steam distillation was comparable with standard apparatus. Thus, the improvised apparatus offers a cheaper alternative for conducting distillation process in chemistry experiments. The cost of performing distillation process is further reduced by using improvised measuring devices to measure the purity of the distillates in lieu of chemicals and reagents. Aside from being cost-effective, the improvised apparatus is easy to construct, durable, user-friendly and safe to use.
Insecticidal potential of Sappan (Cesalpinia sappan) seeds ethanol extract against rice weevil (Sitophilus oryzae)
Authors: Acero Liwayway
Published: July 2024

Insects are known not only as pests at home but in agricultural farms as well. There are insects that even destroy the quality of farm harvest and decrease its palatability and marketability. One of the very well- known insect pests is the rice weevil (Sitophilus oryzae) which damage the quality of rice grain and lowers its market value. Indigenous plant base environment friendly insecticides are now gaining popularity than commercial insecticides. There are many herbal plants in the Philippines which can be used as potential source of insecticide. One of these is Sappan (Cesalpinia sappan) which grows well along riverbanks. The aim of this study was to determine which of the following concentrations (T- control, 0%; T1, 15%; T2, 30% and T3, 45%) of Sappan seed ethanol extract (SSEE) will give the highest mortality in 1.5 h of observation. Experimental research method with four treatments and twenty samples of rice weevils were used to gather pertinent data for this study. Sappan seeds were sundried, chopped, macerated in 95% ethanol for 3 days and subjected to rotary evaporation. Data on mortality for 1.5 h with 15 minutes intervals was analyzed using Analysis of Variance and Fisher Least Significant Difference (LSD) Test as post hoc Test. Results revealed significant difference on the means of four treatments. It is imperative that rice weevils in T3 (45% of SSEE) had highest mortality in 1.5 h exposure. It implied that SSEE is a potential source of insecticide particularly for rice weevils.

Overview of multi-attribute decision analysis tools for selecting an investment option in municipal heat energy
Authors: Dawiec Dominika , Ginda Grzegorz
Published: July 2024

Municipal district heating systems in Polish cities constitute important elements of these municipalities (and not only of their technical infrastructures). Due to the nature of the basic service that is provided - providing heat (and perhaps year-round comfort in the future) - these systems can be perceived as important parts of the social infrastructures of the cities, creating the appropriate conditions for the existence of people, the functioning of social infrastructure facilities, and the operations of enterprises. The need for heating companies to adapt to any changes in the requirements that arise as a result of the economic, social, environmental, and (increasingly) political and legal changes that take place in its immediate and distant environment requires the implementation of investments. However, the effects of such investments are multidimensional and largely difficult to measure; they depend on the passage of time and complex conditions that are related to the pursuit of sustainabledevelopment and security. Their reliable assessment therefore requires the use of appropriate tools. This paper is devoted to an analysis of the practical usefulness of multi-attribute decision-analysis tools in this context, taking various types of such tools into account as well as the conditions for their effective applications. The most promising of these tools is also introduced and discussed.

Natural grazing by horses and cattle promotes bird diversity in a restored European alluvial grassland
Authors: Lovász Lilla , Korner-Nievergelt Fränzi , Amrhein Valentin
Published: July 2024

Context

A challenge in grassland conservation is to maintain both the openness and the heterogeneity of the habitat to support the diversity of their animal communities, including birds—a taxon that is known to be sensitive to disturbance. An increasingly used management tool in European grassland conservation, especially in rewilding projects, is grazing by large herbivores such as horses and cattle. These grazers are believed to create and maintain patchy landscapes that promote diversity and richness of other species, but their influence on birds is often debated by conservationists, who raise concerns about the impact of disturbance by the grazers.

Objectives

Our aim was to examine the relationship between the abundance and species richness of birds across four foraging guilds and the area utilization patterns of Highland cattle and Konik horses in an alluvial grassland in France. We also aimed to examine the influence of land cover and season on the spatial distribution, including abundance and species richness, of different bird guilds present in the grazed area.

Methods

We used GPS-collars on all grazers and recorded their positions on an hourly basis over a study period of 1.5 years, assessing patterns of area usage. We counted birds weekly along three transects to describe their distribution within the grazed area and carried out land-cover surveys to describe the habitat. To assess how species richness and abundance of birds of different guilds were related to grazer density, season, and habitat characteristics, we used GAMM models in a spatially explicit framework. We also compared bird numbers at our main study site with a nearby non-grazed control area.

Results

The number of birds in the grazed area was about twice the number in the non-grazed control area. Within the grazed area, the abundance of open-area foraging birds increased with increasing grazer density. The number of woodland-foraging birds was also positively correlated with grazer density but less so than open-area foraging birds. The number of individuals in the aerial and wetland bird guilds was not correlated with the density of grazers. Most bird species and individuals were observed on open landscapes scattered with woody patches and waterbodies, and on areas with moderate grazer density.

Conclusions

Low-intensity grazing represents a potentially important management tool in creating heterogeneity in alluvial grasslands, thereby promoting suitable habitat for a diverse assemblage of bird species.

Published: July 2024

The experiment was conducted in the agriculture field of the Himalayan university, Jollang, Arunachal Pradesh to find out the effect of different composts and biofertilizers inoculations on black soybean yield. The experiment was set up in a Randomized Block Design (RBD) with three replications. Seven different composts and biofertilizers inoculations and one control treatment were used in the study to assess the effect of different composts and biofertilizers on black soybean yield. The findings of the study showed that vermicompost + phosphate solubilizing bacteria and vermicompost + rhizobium inoculant performed better in all aspects of yield components like number of pods per plant, number of seed per pod, seed weight, grain yield, straw yield, biological yield and harvest index etc. However, the control treatment performed lowest in every parameter. As a result of the experiment, it could be concluded that vermicompost + phosphate solubilizing bacteria has a significant effect on yield component of black soybean.

The case about female presented with chronic fatigue for more than 1 year with progressive weight loss and her basic blood investigations were normal  and mis diagnosed as gastritis due to H-PYLORI Infection with multiple courses of antibiotics but after careful history taking a relation made between onset of her symptoms and her last complicated childbirth followed by failed lactation , so focused laboratory investigations requested to rule out pituitary infarction and secondary adrenal insufficiency which was confirmed and patient started to get the proper treatment and follow up with much improvement later on.
In conclusion, this case demonstrates the typical symptoms and difficulties in diagnosing Sheehan syndrome. While H. pylori infection can contribute to gastrointestinal symptoms, a thorough history taking is crucial to differentiate it from other causes of chronic fatigue and weight loss. This comprehensive approach can prevent unnecessary treatment and ensure timely diagnosis of potentially more serious conditions. It is crucial to regularly follow up and monitor patients with Sheehan syndrome to effectively administer hormone replacement therapy and identify any developing endocrine issues.

Abysmal Hike in Global Cocoa Price and its Implications on Cocoa Plantations in Tamil Nadu - A Critical Analysis
Authors: Sudhalakshmi C. , Lekhavarshinee J. , Latha P. , Suresh J.
Published: July 2024

Cocoa belonging to the family Sterculiaceae has its origin in South America and later it had spread to Europe, Africa and Asia. In Tamil Nadu, cocoa is accommodated as an intercrop in arecanut and coconut plantations especially in South India. But over the past few years, the acreage under cocoa showed a steady decline and the area currently hovers around 5,000 ha especially concentrated in Coimbatore, Theni and Kanyakumari districts of the state. Price volatility is the key player in culminating cocoa plantations in the state. But the recent global shortage of cocoa associated with climatic vagaries and biotic stress like swollen shoot virus and black pod disease in the leading cocoa producers of the world has prompted a positive note in the price of cocoa beans in India. Government policies like ban on deforestation and engaging child labourers for farming and underinvestment in cocoa gardens in the West African countries also added hue to the problem. A record high of ten fold increase in price was observed during the last quarter of 2023 and first quarter of 2024. According to the International Cocoa Organization, global cocoa supply will decline by almost 11% over the 2023/2024 season. Global price has a direct impact on cocoa plantations in the state of Tamil Nadu as many cocoa orchards were cleared due to the lack of remunerative price. But the abysmal price hike in the global front has invited the farmers to rejuvenate the abandoned cocoa plantations and bring new area under cultivation in Tamil Nadu as price was the key player in giving up the crop during 2010s by the farmers. Abysmal hike in global cocoa price has brought a ray of hope for the expanding acreage of cocoa in the state of Tamil Nadu.

A field experiment was conducted at Research Farm, JNKVV-College of Agriculture, Tikamgarh (Madhya Pradesh) during rabi season 2019-20 to assess the effect of phosphorus fertilization and PSB inoculation on growth attributes and root nodulation of chickpea. Results revealed that the vegetative growth parameters were, in general, enhanced very fast between 30 to 90 days thereafter the rise was normally very slow up to the crop maturity stage. Thus, at harvest stage, plant height ranged from 49.5 to 67.9 cm and branches 9.40 to 13.0 plant-1 under various treatments.
Amongst the all treatments, 50 kg P2O5 + PSB + 2% DAP foliar spray resulted in significantly higher number of root nodules plant-1and fresh and dry weight of root nodules plant-1at 30, 45, 60, and 75 DAS followed by 25 kg P2O5 + PSB + 2% DAP spray before flowering stage. Similarly the same treatments also enhanced the fresh and dry matter production per plant up to the maximum extent, being significantly higher to the single applied P levels or with each of PSB and DAP spray.

The experiment was laid out in Randomized Block Design (RBD) with seven (7) treatments and three (3) replications. The treatments taken under the study were Control (T1), Non-woven Red (T2), Non-woven Blue (T3), Non-woven White (T4) Non-woven Green (T5), Non-woven Yellow (T6) and Polypropylene (T7). The maximum fruit weight (17.81g), fruit volume (20.00cc), fruit breadth (3.16cm), fruit length (3.56cm), aril weight (14.28g), peel weight (2.31g) and yield (0.44kg/bunch) were recorded in T4 (Non-woven White). Sun burn (8%) and fruit cracking (5.66%) percentage was observed lowest in T4. During storage, highest shelf life was observed in T4 i.e. 10.50 days. Thus, it can be concluded that all the bags studied in the present experiment were found to be good both in qualitative and quantitative characters and also increased shelf life. But the most superior one among the selected bags was non-woven white bag in terms of morphologicall and shelf life characteristics.

This study investigates the influence of parental control on the academic decision-making processes of young adults. Although the general public has strongly supported parental engagement as a solution for school education, there are still some difficult questions surrounding this topic because the research in this field has shown conflicting results [1]. Academic decisions, such as choice of college major, career path, and educational goals, are critical milestones in the transition to adulthood. The extent to which parental control shapes these decisions has significant implications for personal development and future outcomes. Through a structured questionnaire (google form) surveys, data of 100 respondents from Acharya Narendra Deva University of Agriculture & Technology were collected from a diverse sample of young adults. Findings suggest that parental control manifests in various forms, including direct influence on decision outcomes, indirect shaping of aspirations, and psychological impact on autonomy and self-confidence. The study reveals nuanced dynamics wherein parental involvement ranges from supportive guidance to restrictive directives, influencing young adults' perceptions of their relationship with their parents. When parental participation is viewed as a tool to help children succeed academically, the nature of the independent variable and the degree to which it can influence learning outcomes become research topics in and of themselves [2]. These insights contribute to understanding the complex interplay between familial influence and individual autonomy in the educational and career pathways of young adults.
Geological storage of CO2 within the oceanic crust by gravitational trapping

The rise of atmospheric carbon dioxide (CO2) principally due to the burning of fossil fuels is a key driver of anthropogenic climate change. Mitigation strategies include improved efficiency, using renewable energy, and capture and long‐term sequestration of CO2. Most sequestration research considers CO2 injection into deep saline aquifers or depleted hydrocarbon reservoirs. Unconventional suggestions include CO2 storage in the porous volcanic lavas of uppermost oceanic crust. Here we test the feasibility of injecting CO2 into deep‐sea basalts and identify sites where CO2 should be both physically and gravitationally trapped. We use global databases to estimate pressure and temperature, hence density of CO2 and seawater at the sediment‐basement interface. At previously suggested sites on the Juan de Fuca Plate and in the eastern equatorial Pacific Ocean, CO2 is gravitationally unstable. However, we identify five sediment‐covered regions where CO2 is denser than seawater, each sufficient for several centuries of anthropogenic CO2 emissions.
Near‐field tsunami models with rapid earthquake source inversions from land‐ and ocean‐based observations: The potential for forecast and warning
Authors: Melgar Diego , Bock Yehuda
Published: November 2013

Computation of tsunami models in the region adjacent to large earthquakes immediately after rupture initiation remains a challenging problem. Limitations of traditional seismological instrumentation in the near field and concern by tsunami modelers regarding the nonuniqueness of source inversions and the use of indirect observations have in the past been hurdles for such efforts. Employing near‐field data from the Mw 9.0 2011 Tohoku‐oki data, we test source models obtained from newly developed algorithms and multisensor data. We demonstrate the ability of such source models determined from land‐based coseismic data from the combination of GPS and strong‐motion sensors to forecast near‐source tsunamis. We also demonstrate that rapid ingestion of offshore shallow water (100–1000 m) wave gauge data substantially improves the earthquake source and tsunami forecast. To assess the success of such tsunami models, we rely on detailed comparisons to 2000+ tsunami survey measurements collected after the event. We argue that deployments of shallow water wave gauges coupled with land‐based geophysical sensors can, in the future, provide enough information to issue timely and accurate forecasts of tsunami intensity immediately or shortly after rupture initiation of large earthquakes.
Wind to zooplankton: Ecosystem‐wide influence of seasonal wind‐driven upwelling in and around the Delaware Bay

Published: November 2013

We synthesized historical records of wind, temperature, nutrients, phytoplankton, and zooplankton to produce a climatological view of the biological response to upwelling in an estuarine/coastal system, the Delaware Bay, and surrounding coastal ocean. We find a persistent, rather than episodic, impact of upwelling near the mouth of the bay from May to September. During the upwelling season, the average sea surface temperature for the upwelling region is 2–3°C colder than the adjacent Delaware Bay and coastal ocean waters. This temperature difference is well correlated with the alongshore wind stress in the summer, making temperature a suitable upwelling index for the region. The upwelling apparently delivers subsurface nutrients to the lower bay and surrounding coastal ocean that help support phytoplankton primary production. Despite high primary production, the phytoplankton biomass (chlorophyll) does not increase accordingly. The lack of biomass increase is well correlated to seasonal increases in zooplankton biovolume. This result suggests that persistent upwelling near the Delaware Bay is characterized by an efficient transfer of carbon to primary consumers.
Origin and pathways of Winter Intermediate Water in the Northwestern Mediterranean Sea using observations and numerical simulation

Published: November 2013

The study of water masses worldwide (their formation, spreading, mixing, and impact on general circulation) is essential for a better understanding of the ocean circulation and variability. In this paper, the formation and main pathways of Winter Intermediate Water (WIW) in the Northwestern Mediterranean Sea (NWMED) are investigated during the winter‐spring 2011 using observations and numerical simulation. The main results show that the WIW, formed along the continental shelves of the Gulf of Lion and Balearic Sea, circulates southward following five preferential pathways depending on the WIW formation site location and the oceanic conditions. WIW joins the northeastern part of the Balearic Sea, or flows along the continental shelves until joining the Balearic Current (maximum of 0.33 Sv in early‐April) or further south until the Ibiza Channel entrance. Two additional trajectories, contributing to water mass exchanges with the southern part of the Western Mediterranean Sea, bring the WIW through the Ibiza and Mallorca Channels (maxima of 0.26 Sv in late‐March and 0.1 Sv in early‐April, respectively). The circulation of WIW over the NWMED at 50–200 m depth, its mixing and spreading over the Western Mediterranean Sea (reaching the south of the Balearic Islands, the Algero‐Provencal basin, the Ligurian and the Alboran Seas) suggest that the WIW may have an impact on the ocean circulation by eddy blocking effect, exchange of water masses between north and south subbasins of Western Mediterranean Sea through the Ibiza Channel or modification of the ocean stratification.
Effects of nonlinear physical processes on optimal error growth in predictability experiments of the Kuroshio Large Meander

Published: November 2013

Within a 1.5‐layer shallow‐water model, the effects of nonlinear physical processes on the optimal error growth in the predictability experiments of the Kuroshio Large Meander (LM) are investigated. To clarify these effects, we use both the conditional nonlinear optimal perturbation (CNOP) and the first singular vector (FSV) methods. By examining the nonlinear evolution of the CNOPs and the FSVs, we find that the nonlinear physical processes play an important role in the error growth, in particular for the initial errors with large amplitudes. The specific roles of nonlinear processes in error growth are identified by determining the error development in modified nonlinear equations in which particular terms are neglected. The results demonstrate that advection of momentum perturbations, associated with the nonlinear development of barotropic instabilities, tend to enhance the evolution of the errors and cause the forecasted Kuroshio Large Meander to be strengthened. The nonlinear process related to the divergence of velocity perturbations caused by upper‐layer thickness perturbations enhances the optimal error growth, whereas the advection of upper‐layer thickness perturbations by velocity perturbations suppresses it.
