Formation of upper anticyclones and their Blocking activity during winter over Asia
Authors: GUPTA M. G. , RAJAGOPALAN K. S. V. 
Published: May 2022

The results of the study of 65 cases of the formation of anticyclones in the upper westerlies over Asia and adjoining west Europe, their areas of occurrence and blocking activities, during the winter and transition season of November-April, are presented in this paper. It has also been shown with the help of a detailed case-study of 1-7 April 1969, that the anticyclones which formed over Iran and persisted for more than 5 days behave as blockingsystems and dominate the circulation over Asia. These blocks are however weak when compared with Atlantic and Pacific cases but satisfy all the well known characteristics of blocking action.
Further studies on runway temperature and Screen temperature observations made At Dum Dum Airport, Calcutta
Authors: DE A. C. 
Published: May 2022

Result of a study of runway and screen temperature observations made at Dum Dum airport, Calcutta at six synoptic hours (00, 03, 06, 09, 12 and 18 GMT) for a period of 21 months was reported earlier by the author. The same has now been extended for a further period of 24 months. The result of the study for the entire period of 45 months, reveals that the runway temperature is generally higher that the screen temperature, the average value of difference of runway and screen temperature readings being generally less than 1oC. In extreme cases, the absolute value of the difference could be as high as ± 4oC. The diurnal and seasonal variation of the difference has been discussed. The effect of surface wind, radiation and other factors on the value of the difference has been also discussed.

Authors: SAMBASIVARAO A , VAMADEVAN VK 
Published: May 2022

Under humid tropical conditions, the relative evaporation .rates from Class A open pan, G.G.I. 3000 and Colorado sunken pans were studied.. The recorded evaporation values were compared with evaporation estimated with a modified Penman equation. The Inter relationship between evaporation values and the influence of weather parameters on evaporation were also studied using statistical correlations.
About 88-93 per cent of insolation was absorbed from the pan surfaces for evaporation. The seasonal variation of evaporation was between 4 and 10. mm/day and the variation In evaporation due to type of pan used was up to 3 mm/day. The estimated evaporation values were within +-2.0 mm/day from the measured values. The evaporation values from the sunken pans were higher than from Class A by 1-3 mm/day and they were also closely correlated. The aerodynamic parameters were closely correlated with evaporation from Class A than from the sunken pans. The high soil thermal regime the area during October to May has increased the evaporation from the sunken pans.

The heatflux into an oxisol under coconut in an humid tropical climate was analysed.
The peak daily solar radiation and air temperature during dry period (December-May) in this region goes upto 1050 Wm-1 and 35° C respectively. The maximum surface soil (2,5 cm depth) temperature observed in an open field was 62° C on a summer day. The diurnal variation of soil temperature in the open field was between 33° and 45°C at 5 cm depth and it was reduced by 2-7° C due to coconut canopy and by 1-7° C due to natural mulch material.
The heat capacity and diffusivity values of the soil were 0.4315 cal cm-2 oC-l and 0.596 x l0-3sec-1 respectively at PWP (permanent wilting point) moisture content. The diurnal heat flux into 5-10 cm layer of soil was between +0,412 and -0,165 cal cm-1 h~ in the open field, whereas it ranges between +0,494 and -0.296 cal cm-1hr-l in the coconut garden. The maximum surface heat flux into 2.5-5.0cm depth was 6.42 cal cm-1 hr-l.
Mulching around the basin of the coconut tree causes heat flow to be either at equilibrium or negative.
The maximum heatflow into 5-10 cm layer (1430 IST) was up to 0.849 cal cm-. hr-1 in different seasons and it is not related to soil moisture content.

The severe drought in Greece during the winter and spring 1977 is described. The behavior of drought-characteristic meteorological parameters IS then studied along with the large-scale air mass in the upper atmosphere.
Using wind, temperature humidity data, it is shown that the prevailed cloud-destructive downward
movements prevented precipitation. The probability for precipitation was further reduced once the drought had been established, due to changes In energy and water balances,
Finally an explanation of the drought-inducing meteorological anomalies is attempted.
Study of certain sudden weather developments Over central India in winter
Authors: SENGUPTA S , MARATHE SD 
Published: May 2022

Most of the winter rains In central India are associate with systems Induced by western disturbances and, sometimes, as an effect from the moving cyclonic systems In the extreme south of the country, But, there are instances of sudden winter wet spells localised in the central parts of the country in the absence of any such system, This study shows that, some of the sudden widespread rains in central India are actually associated with highly amplified lower tropospheric easterly waves from the Bay of Bengal progressing across the Peninsular India and bringing in considerable moist air into the dry regions of the central India to cause vigorous weather there, Isentropic method has been used to locate the ascending moist air around central India and determine its vertical velocity. It has been shown that this vertical lift is further augmented by the favourable position of an upper tropospheric jet stream located in the area in each case, thus causing vigorous convective activity.

Published: May 2022

A multiplicative seasonal ARIMA model of order (0, 1, 1) X (0, 1, 1) has been applied for the prediction of monthly flow (x) in Sutlej at Bhakra dam site, using 40 years (1925-64) discharge data.
The accuracy of prediction has been tested by using seven years (1965-71) observations. The root mean square error for the forecast period was calculated. It is found that the root mean square error varies from 3 per cent 1n December to about 43 per cent In September.
Forecasting of thunderstorms in pre-monsoon season over northwest India
Authors: DHAWAN VB , TYAGI AJIT , BANSAL MC 
Published: May 2022

Early detection and forecasting of thunderstorms is important in safeguarding and prevention of damages resulting from violent thunderstorms. An Expert System for Thunderstorm Forecasting (ESTF) during pre-monsoon season over Delhi the representative location over northwest India has been developed for the first time in India by using technique of approaching the problem “bottom up” by using inductive machine learning techniques to automatically acquire the knowledge about thunderstorm forecasting from the weather development data set consisting of TEMP data of Delhi for the months of May and June for the years from 1995-1999. Only input required is the entry of 0000 UTC TEMP data of Delhi at surface, 850, 700, 500 and 300 hPa levels. The rules are based on stability indices and other thermodynamic parameters evaluated from the said sounding. The system also provides climatological information about thunderstorms over Delhi. To compare the ESTF with the objective techniques, Dynamical-statistical methods for yes or no type thunderstorm occurrence forecast over Delhi during pre-monsoon months of May and June have been developed by using graphical discrimination method and multiple regression method and by using the same development data set i.e., TEMP data of Delhi for the months of May and June for the years from 1995-1999 and by using the same potential predictors as used in development of ESTF. In multiple regression method the parameters were found to be significant by stepwise screening procedure. The three methods developed were tested with independent data sets of May and June for the years from 2000-2001. Comparison of verification parameters of the forecast issued by Graphical Discrimination method, Multiple Regression Technique and by ESTF indicates that results of multiple regression method are better than those of graphical discrimination method. The results obtained by using ESTF were better than those obtained by using dynamical statistical models.

Pre-monsoon is a very challenging period for regional duty-forecasters and those involved in mitigation of severe weather consequences. Indeed, violent thunderstorms producing high winds, large hail and even tornados are common features from March to May in East India and Bangladesh. Taking advantage of SAARC (South Asian Association for Regional Cooperation) research publications, as well as knowledge and practical methodology developed by NOAA’s National Weather Service in the Tornado Alley, a methodology is proposed that might help IMD forecasters make the best use of their new workstation SYNERGIE. The case study of the 13 April 2010 severe storm has been chosen for this purpose. More than 140 reported deaths and nearly 500,000 people were left homeless or otherwise affected by the storm. A good comprehension of both synoptic and mesoscale conceptual models is needed; then, aided by appropriate numerical model fields, drawing proper weather symbols on surface analysis charts is an important step towards the building and sharing of local expertise with regional or local forecasters. A graphical analysis is proposed and discussed.

Authors: Calamayo Judith 
Published: May 2022

The country’s effort of improving the student services programs is paralleled by the International Association of Student Affairs and Services (IASAS), an informal confederation of higher education student affairs/services professionals from around the world. Its members have been actively engaged for improving communication and sharing of professional development experiences such as best practices, internships, exchanges, conferences, colloquia and symposia. The status of implementation of student services programs of Northwest Samar State University (NwSSU) on terms of student welfare, student development, and institutional student services programs was very satisfactory. There is no significant difference in the status of implementation of student services programs of NwSSU in terms of student welfare, student development, and institutional student services programs with the different program components such as objectives, personnel, projects/activities, budget, facilities/equipment and monitoring and evaluation. The primary problems in the implementation of student services programs of NwSSU includes lack of qualified personnel, lack of facilities and equipment and lack of cooperation among partner agencies. Recommendations such as seminars / sessions on Personality Development Program and Proper Handling of Student Services Clients be conducted by the SAS Personnel; increase the number of personnel in the Registrar’s Office, Guidance Office and Medical – Dental Clinic; hire licensed, educationally qualified librarians and guidance counselors; increase the budget allocation for the purchase of medicines; have a separate room for testing and group counseling purposes; procure additional copies of test materials; update the facilities and equipment in every SAS Unit, especially, the units with fiduciary fund.
Condensación de la humedad del aire: solución a la escasez de agua en regiones de Colombia como La Guajira y San Andrés Isla
Authors: Galindo Torres María Dolores , Gregorio Contreras José , Mendoza Ortiz Alexánder 
Published: May 2022

La Escuela Tecnológica Instituto Técnico Central, desde su centro de investigación y con el Grupo de Estudios Ambientales (GEA), se propuso ayudar en una solución al problema de fuentes de agua dulce y potable para ciertas regiones del país donde el régimen de lluvias y las fuentes de agua potable escasean. Por tal razón, se formula el proyecto Prototipo Autosostenible para Obtención de Agua Potable Condesada a Partir de la Humedad del Aire.
A través de la metodología de ingeniería inversa se modificó un aire acondicionado de ventana que funciona con refrigerante R22, con el cual se lograron condesar 37,5 litros de agua en 24 horas de operación, con un consumo de energía eléctrica de 24,13 kW-h, prueba realizada en la ciudad de Bogotá. Con otro equipo en San Andrés isla –de A/C, que funciona con R410a– se obtuvieron 24,84 litros de agua en 15,61 horas, con un consumo de 8,36 kW-h.
Dentro de la investigación también se logró establecer que el agua condensada, por los sistemas de aire acondicionado, se drena al alcantarillado: No se utiliza, puesto que la creencia entre los usuarios es considerarlo como un producto tóxico que afecta la salud. En respuesta a esto, se tomaron muestras a las que se les realizaron pruebas; los resultados mostraron que el agua no es tóxica y se puede potabilizar, utilizándola para consumo humano. Esta otra fuente de agua dulce puede llegar a solucionar, en parte, la escasez en las regiones antes mencionadas.

Cosmic Breakthrough: the first direct detection of gravitational waves and its significance
Authors: Hamilton Maria Babiuc 
Published: May 2022

We have gazed at the night sky since the dawn of time, marveling at the beauty of the cosmos and trying to understand its inner workings. Now we can “hear” it: tiny ripples in the very fabric of space time, that tell stories of great cosmic cataclysms. The first gravitational waves were detected on September 14, 2015 and was revealed to the public on February 11, 2016. Their prediction though was made 100 years ago, by Albert Einstein, as part of his famous general theory of relativity. What are gravitational waves? Why did it take so long to find them? Where do they come from? How does their discovery change our understanding of the cosmos? Those, are the questions I will answer. Finally, I will talk about my own contributions to this field.
Using Social Networking APIs to Collect Real-time Data for Analytics
Authors: Liao Weidong , Chhoeut Robert 
Published: May 2022

Social Media platforms have been widespread since the advent of web 2.0, ever since, users have been contributing content in the form of various media such as text messages, pictures, video, blog posts and other formats. The scale of data amassed from these contributions offer opportunities for data mining and analytics which in turn may offer meaningful interpretations. Currently various tools exist for fetching and analyzing social media data. The purpose of this project is to uncover methods for fetching real-time data among various social networking platforms for analytical use. APIs (Application programming interfaces) exist for simplifying an implementation of an application’s functionality. Using APIs such as Twitter4j, Restfb, and Google+ API, a Java test application was written to utilize API search features in to retrieve various queries of data. The result was a test application which retrieved and outputted data into a file. However the drawbacks were API authentication requirements, data fetching rate limit restrictions, and deprecated/removed features. In general APIs offer a solution in fetching data and building applications, but may include restrictions for the public’s access depending on Social Media platform.
