Delving into the physical education teachers’ teaching performance as a factor of students’ academic achievement
Authors: Nochefranca Almira E. 
Published: May 2022

The success of teaching is largely dependent on teachers’ performance. It defines and shapes the success of a school and determines the quality of services and outputs of the school can provide and produce. This is the reason that school principals promote and maintain high level of teaching performance among their teachers (Garton, et al., 2000). In the teaching – learning process, the teacher and student are the important figures. The interactions of these individuals in the classroom complete the education process in a given time. In other words, the link is evident between the teacher and the student – the amount of efforts a teacher exerts will tantamount to the student learning. This study focused on the performance in the National Achievement Test (NAT) of selected Physical Education teachers of the secondary schools in the Division of Zamboanga City where their teaching performance was gauged using the survey questionnaires while the academic performance of the 372 students was analyzed through the result of their National Achievement Test.

Published: May 2022

To establish relation between fetal MCA’s PSV in 3rd trimester and fetal anemia as non-invasive method. The study was done retrospectively, including 40 pregnant women who had raised PSV of MCA (Multiple of Median(MoM) >1.5) blood flow in third trimester and was correlated with the new born’s Hemoglobin and Blood indices (MCV and MCH). Forty fetuses who had MCA’s PSV more than 1.5 MoM(coming out to be around 66.50 ± 12.35 cm/seconds), after delivery, blood samples of these 40 neonate were taken, of which 37 were anemic based on hemoglobin and blood indices using reference range from study done by kumar et al8. Sensitivity was 92.5% and specificity around 88 %. Doppler spectral analysis of PSV of MCA is very reliable for predicting fetal anemia. MoM of PSV of Fetal MCA correlates very well with MoM of Neonatal Hemoglobin . Thus, fetal MCA’s PSV is very potential to replace invasive method for diagnosis of fetal anemia.

Authors: RUDRAIAH N 
Published: May 2022

The effects of uniform rotation and non-uniform temperature gradient on the onset of India according of Marangoni convection driven by surface tension in a horizontal layer of fluid is studied subjected to infinitesimal amplitude analysis assuming both the bounding surfaces free and adiabatic. A single term Galerkin technique with single term expansion is used to obtain the eigenvalues which are then computed numerically. Attention is focused on the situation where the. Critical Marangoni number is greatest or least than that for the uniform temperature gradient. Numerical results are obtained for special cases and some general conclusions about the destabilizing effects or various basic temperature profiles and the stabilizing effect of Coriolis force are presented. It was round that the most destabilizing temperature gradient is one for which the temperature gradient is a step function of the depth and the most stabilizing temperature gradient is inverted parabola and the Coriolis force has inhibiting effect on the onset of Marangom convection.

Network design .has of late assumed very great importance in .all water resources investigations. Though many techniques are available for planning network for different hydrological parameters yet many difficulties are experienced in the collection of observations with desired accuracy. Spatial variation of the hydrological variable is an important factor, which has to be duly considered. In addition to this, there are various practical difficulties in collecting the observations as dictated by theoretical considerations The mountaineous catchments further add to these problems.
In the present paper, an attempt bas been made to study the precipitation network design using Kagan's technique (1966). It also highlights the various practical field problems involved in implementing the desired network from theoretical considerations. A case study has been done for 'Purna catchment', a tributary of river Tapi in Maharashtra.

Formation and structure of a monsoon revival depression over the Bay of Bengal during a 'break' monsoon period
Authors: KOTESWARAM P , RAO CPOORNACHANDRA , KRISHNAMURTHY M 
Published: May 2022

Formation and structure of a monsoon revival depression (MRD) over the Bay of Bengal during the monsoon 'break' of August 1977 are studied with the aid of six hourly rawinsonde ascents made by a polygon of four oceanographic research vessels of the USSR participating in the joint Indo-USSR Monsoon '77 expedition. It is found that a mid-tropospheric cyclone (MTC) initially developed over the East Central Bay (ECB) under the influence of an upper easterly wave (UEW) moving westwards across the Arakan coast of Burma and descended to the surface as MRD after the MTC had moved northwestwards for more than 24 hour. The MTC formed at the west-east interface (WEF) between the monsoon westerlies and the upper easterlies and developed upwards and downwards under the influence of the upper vorticity advection in the UEW. It was oscillatory, reaching its maximum vertical extent upto 200 mb (as a narrow core) just before it descended to the sea level. The MTC in the mid-troposphere was located to the southwest of the MRD in the lower troposphere and was warm cored while the MRD was cold cored. It is postulated that all monsoon depressions have similar origins and structures.
The structure of a break monsoon cell in the vertical and the mechanism of the formation of the MRD by superposition of the MTC and UEW are postulated schematically. It is pointed out that monsoon revival after a break takes place not by northward movement of a fresh oceanic intertropical zone of convergence (OITC) from the south Bay but by the return of the continental OITC from Burma to the north Bay under the influence of a UEW.

Published: May 2022

To know the role of meteorological systems of synoptic scale in outbreaks of desert locust (Schistocerca gregaria Forsk) at various phases of its life cycle in western India, data on locust situation and synoptic disturbances during period from 1945 to 1980 were analysed.
The analysis of the fortnightly data of the infestation of egg layings, hoppers, scattered adults and swarms for seven stations shows that the chronological orders of these activities follow the spatial progress of the normal monsoon onset with pre-monsoon rains. However, the highest swarm activity was found in the first fortnight of August.
Simple linear correlation technique was used to know the degree of association of various meteorological disturbances with locust activity at different stages for a station with good record of data set. The egg-laying activity was parallel with rainfall and slight decrease in rainfall between peaks did not affect the activity- Hopper emergence peaks were seen generally after a month of rainfall. Scattered adults activity showed no good association with rainfall. The swarms intensity was highest during first fortnight of August and September. The main meteorological systems causing rainfall were western disturbances, depressions over Arabian Sea and a few depressions developed over land.
It was also found that a negative correlation exists between swarm infestation and sunspot number.

Published: May 2022

Knowing the area under each crop and their water requirements, it is possible to plan the water resources for storage and distribution from the reservoirs, ponds, lakes etc. Since most of the north coastal Andhra regional rain fed area, it is essential to estimate the water requirement of the crop either to change the cropping pattern or to schedule the irrigation facilities. For this study, Blaney and Criddle1950) method has been adopted since this method IS suggested for area where available climatic data consists of air temperature data alone. Three representative stations, Kalingapatnam, Visakhapatnam and Anakapalleh have been taken and estimated the normal water requirements for the principal crops grown in the region.
Verification of model predicted precipitation over India during the summer monsoon of 1997
Authors: BASU B. K. 
Published: May 2022

For the monsoon season of 1997 the precipitation observation from 1333 rain gauge stations are used to form spatial averages for 135 grid points of the NCMRWF forecast model covering the whole of India. These spatial averages are compared with the model forecasts of precipitation by computing the mean error, mean absolute error, root mean square error and correlation coefficient. The skill of forecast is also computed by discretizing the precipitation amounts in to standard categories.

The seasonal accumulated precipitation and its spatial distribution are well reproduced in the model predictions up to 4-days in advance. The mean error in prediction shows spread of precipitation across the Western Ghat hills as the barrier effect is under estimated in the model due to poor horizontal resolution. The correlation coefficient shows good in-phase relationship between the predicted and observed precipitation especially over areas of very large seasonal precipitation. Over a small area this coefficient has values higher than 0.6. The model has skill for categories of precipitation with class mark up to 1.0 inch and prediction lead-time up to 2 day.

In 1997 no low frequency south to north propagating mode is present in the observed box average precipitation.

Published: May 2022

A synoptic climatological analysis of pentad rainfall anomalies for 52 blocks over India for southwest monsoon season for the years 1901 to 1980 has been carried out to identify events of anomalous heavy rainfall over the western part of the monsoon trough area and study the change in rainfall distribution over central parts of the country in subsequent three pentads. This analysis is based on the results of a diagnostic study by Bhide et al. (1997) which showed that the events of development of diabatic heat sources due to convective heavy rainfall over the western part of the monsoon trough area were followed by the occurrence of a weak or break phase during monsoon 1979.

An event of positive pentad rainfall anomaly (SA) for a test area TA on the western part of the monsoon trough is considered as a basic synoptic event. SA is categorised into five classes C1 to C5 having ranges between –1 and 9. The change in rainfall anomalies for subsequent three pentads is studied. The pattern of rainfall anomalies for class C5, having the largest values of SA indicates development of a break phase over India and confirms the earlier observation for monsoon 1979. The development of a weak phase is indicated for class C4.
A synoptic study of active and weak southwest monsoon over Andhra Pradesh
Authors: BHADRAM C. V. V. 
Published: May 2022

An attempt has been made in this study to identify the synoptic systems that cause active or vigorous monsoon conditions over the three meteorological sub-divisions of Andhra Pradesh using the data for the years 1986 to 2000. Despite significant decrease in the frequency of formation of monsoon depressions in recent years, monsoon performance is noticed to be very good. Monsoon lows and upper air cyclonic-circulations (cycirs) found to be the chief synoptic systems which activate the monsoon over the state. Typical cases of these synoptic situations are discussed.
Evaluation of thermodynamics of the atmosphere in relation to pre-monsoon convective activity over north India
Authors: ROY SOMA SEN , ROY BHOWMIK S. K. 
Published: May 2022

This paper explores the relationship between the vertical structure of the atmosphere and variation of deep (precipitating) convection over north India during pre-monsoon months using data for the year 2001. From the model analysis field, CAPE and other thermodynamic parameters for Kolkata, as representative of east India and Delhi, as representative of northwest India, are computed. The vertical vorticity profiles for these two stations have also been calculated. The study reveals that both for Kolkata and Delhi CAPE is poorly correlated with the rainfall amount. However, the encouraging result is that it has reasonably good skill score (bias and threat scores) to explain occurrence or non-occurrence of convective activity on the subsequent day. Time evolution of vertical structure of atmosphere indicates that nature of convective activities over Kolkata changes as the season advances. The rainfall becomes more dependent on lower tropospheric vorticity and moisture conditions become conducive for deeper convection and taller convective clouds to form with the advance of the season due to a significant increase in the lower tropospheric vorticity. This strengthening of the dynamic support to convective rainfall may be because of the pre-monsoon synoptic pattern becoming more pronounced with the progress of the season. Over Delhi, rainfall dependence on moisture is more at the beginning of the season. As for Kolkata, in this case also character of convection changes as season progresses, with increasing dependence of rainfall on lower tropospheric vorticity field. However, dynamic support is not an important initiator of convection over Delhi. The study also suggests that, the day to day drying of the atmosphere in the lower levels over Kolkata is due to subsidence of upper layer dry air while over Delhi, horizontal advection is mainly responsible for the change in moisture content of the atmosphere.
Teleconnections of Indian summer monsoon with global surface air temperature anomalies
Authors: PAI D. S. 
Published: May 2022

Evolution of prominent teleconnection patterns in the monthly global gridded surface air temperature anomalies associated with the interannual variability of Indian Summer Monsoon Rainfall (ISMR) were examined using data for the period 1901-98. Useful precursory signals for the subsequent ISMR were also identified. Teleconnection patterns showed significant signals from various geographical areas all over the globe. In the land, the temperature distribution over the Eurasian region, which is significantly influenced by the Northern Atlantic Oscillation (NAO) showed the most significant teleconnection with the ISMR. In the oceanic region, teleconnection signals were observed from most of the tropical ocean basins.

Authors: PRASAD RAJENDRA , SINGH HARI , LAL B. 
Published: May 2022

The persistence, intensification and recession of districtwise meteorological drought over India during 1987 have been studied using cumulative weekly rainfall deficiencies (%) from the normal during the southwest monsoon season (June-September) for 355 districts of India. These features have been analysed in northeast, North and Peninsular India during three distinct phases of southwest monsoon, viz., progress ( 9 weeks), active ( 6 weeks) and retreat phase ( 3 weeks).

A prolonged dry spell emerged over a vast region of northwest India up to mid August due to the absence of major weather systems, leading to intense drought conditions. Mixed mode persistence prevailed throughout monsoon season over 65 districts. Unimode persistence of severe intensity occurred in 209 districts over different parts of India. Intensification of drought was more prominent in north India affecting 67% districts. Recession of drought occurred in 40% and more districts in northeast and Peninsular India respectively.
Weather based operational plant protection of leaf spot disease of groundnut
Authors: CHATTOPADHYAY N. , SAMUI R. P. , WADEKAR S. N. 
Published: May 2022

Sensitivity of weather to the incidences of the leaf spot disease on groundnut was studied. Using data collected by PPQ & S during regular survey in different parts of the country it was observed that the disease occurred more frequently in Andhra Pradesh, Karnataka, Gujarat and Maharashtra both in kharif and rabi seasons from 1988-1998. Weather systems causing drop in temperature associated with rainfall and overcast condition leading to increase in relative humidity favoured incidence of the disease particularly when the crop was in pod formation to maturity stages. Decrease in maximum temperature £30° C and increase in morning and afternoon relative humidity ³ 80% and 60% respectively under cloudy condition (2 - 8 okta) associated with rainfall were found to be congenial for the development of the disease in moderate to severe intensities. This weather based information along with field observations on incidence of this disease could be used to forewarn the incidence of the leaf spot disease on groundnut for taking plant protection measures at appropriate time through Agromet Advisory Service.
