Objective
To impart theoretical and practical knowledge about basic physical processes in the atmosphere with an aim to apply in agriculture.

Theory

UNIT I
Atmosphere and its constituents, weather and climate; meteorology and climatology, meteorological elements, instruments for measurement of meteorological elements, meteorological observatory, weather satellites, websites of meteorological organizations – IMD, NCMRWF, IITM, WMO.

UNIT II
Sun and earth; seasons, solstices and equinoxes, solar radiation and laws of radiation, solar constant; radiation receipt on earth surface, heat balance of the earth and atmosphere.

UNIT III
Variation of pressure and temperatures with height; hydrostatic equation, atmospheric moisture; vapour pressure; saturation deficit; psychometric equations, lapse rates, atmospheric stability, tephigram, potential temperature.

UNIT IV
Climatic controls, seasonal distribution of climatologically elements (radiation, temperature, pressure and precipitation) over latitudes.

UNIT V
Clouds and their classification, precipitation processes; artificial rain making, thunderstorms and dust storms; haze, mist, fog and dew, introduction to evapotranspiration,

UNIT VI
Pressure gradient; coriolis force; cyclones and anti-cyclones, local wind systems; land and sea breeze circulation, mountain and valley winds, air masses and fronts,

UNIT VII
Weather charts, forecasting methods – short, medium and long range forecasting techniques, numerical weather prediction.

UNIT VIII
Climatic classification: Koppen and Thornthwaite systems, agroclimatic indices, agroclimatic zones; different agro ecological zones for India.

UNIT IX
