Atmospheric Physics
The features to be investigated are mainly four aspects viz. Thunderstorms electrification and Lightning, Atmospheric dispersion of pollutants, Variability of Indian Summer Monsoon and Risk assessment of the environment due to the presence of the Radioactive radiation/sources. The investigations will largely serve the purpose of project related to practical fulfillment of degree of our M.Sc. and M.Phil students as well as our research activity.
a) Thunderstorm electrification and Lightning:
= Characteristics of IFIA at severe atmospheric disturbances
= Lightning as a major source of NOx and its influence on temperature profile
= Study of convective rainfall
= Statistical variation of electric field
= Thunderstorm activity on global electric circuit
= Lightning distribution and intensities
b) Atmospheric dispersion of pollutants:
The problem of transport of air pollutants is a common interest for all. The transport of pollutants depends largely on the meteorological conditions. The following phenomenon will be examined:
= Atmospheric dispersion of static emissions
= Influence of winds on pollutants
= Ventilation coefficient and prediction of virtual temperature for the next day
= Emissions from vehicles and dispersion
c) Variability of Indian Summer monsoon:
Indian Summer Monsoon is the important synoptic disturbance in determining seasonal rainfall. Monsoon contributes almost 70% of the annual rainfall. Therefore prediction and distribution total rainfall is a tool for planning the crop pattern.
The following phenomenon will be examined:
= Variability of premonsoon and monsoon rainfall
= Short range forecasting of monsoon
= Characteristics of monsoon cloud bands
= Rain attenuation in radio communication
= Thermodynamic structure of troposphere
= Raindrop size distribution
d) Risk assessment of the environment due to the presence of radioactive radiations/ sources:
= Detection and analysis of radioactive sources
= Exposure rate of radiation
= Radiation risk assessment
= Impact on socio-economic aspects and health problems
