Basic aspect of atmosphere, climate, weather
Definition on atmosphere – role of atmosphere on the earth – layers of atmosphere – content of atmosphere – definition of weather and climateexamples for types of weather and climate.
Basic aspect of rainfall and their application in crop production
Rainfall theory – different process – rainfall classification based on the intensity – effective rainfall on crop production.
Basic aspect of temperature and their application in crop production
Cardinal temperature – hot wave – cold wave – enzyme activity in plant
Basic aspects of relative humidity, cloud cover and their application in crop production
Types of humidity – humidity and crop production – humidity and pest and disease – cloud cover classification and crop production
Basic aspects wind, wind direction and their application in crop production
Wind speed and units – wind speed and cyclone – wind direction identification and their crop production.
Three weather codes and crop production
Normal weather and crop production; Sub normal weather and crop production; and abnormal weather and crop production.
Crop production risks and their management
Inherited risk– transferable risk– risk reduction through technology– definition and management aspects.
Drought– floods– extreme rainfall– hot waves– cold waves – thunderstorm– cyclone– pest and disease outbreak– abnormal wind speed under normal weather conditions– fog and mist.
Crop weather interactions and definition
Response of crops to different weather elements
Weather sensitive crops, stages and farm operations
List of weather sensitive crops– weather sensitive stages and weather sensitive farm operations
Basic aspects of crop weather relationships weather sensitive crops weather sensitive crop stages weather sensitive farm operations
Wheat, rice, maize and weather
Role of rainfall, temperature, wind and other important weather elements on wheat, rice, maize crop production.
Sorghum, groundnut, pigeon pea and weather
Role of rainfall, temperature, wind and other important weather elements on sorghum, groundnut, pigeon pea crop production.
Cotton, sugarcane and weather
Role of rainfall, temperature, wind and other important weather elements on cotton and sugarcane crop production.
Sugarbeet, chickpea and weather
Role of rainfall, temperature, wind and other important weather elements on sugarbeet and chickpea crop production.
Sunflower, mustard and weather
Role of rainfall, temperature, wind and other important weather elements on sunflower and mustard crop production.
Genesis of weather forecast in India and abroad
History of weather service and development over years in India and abroad
Types of weather forecast and details
Present resolutions of weather forecast considering the administrative divisions – Now cast– source of release– lead time– accuracy– clients; short range forecast– – source of release– lead time– accuracy– clients; medium range forecast– source of release– lead time– accuracy– clients
Types of weather forecast and details –contd.
Long range forecast– source of release– lead time– accuracy– clients; seasonal climate forecast– source of release– lead time– accuracy– clients; Integrated weather forecast and its usefulness to clients.
Simple methods of verification of weather forecast with real event
HK score, HSS score, ratio score or HIT score, correlation, RMSE
Traditional knowledge on weather forecast and their validity
Prevailing traditional knowledge on rainfall under short, medium and long range scale– their validity with real event–
Weather thumb rules and their validity
using developed thumb rules under prevailing weather parameters for carrying out farm operations to reduce the risks
Inviting questions from 1a to 4e
Presentation of selected question and answer

Presenting prepared agro advisory for Indian condition
Mass communication mode of agro advisories and their effectiveness
News papers– radios– television– mobile SMS– hosting in the website– social networking– climate manager / monsoon manager at village level –empowering village level climate managers / monsoon manager to mass communicate weather forecast and its related advisories– inviting questions for next lesson for discussion.
Discussion on weather forecast and agro advisory from different website
Website of IMD– Website of SAUs – Website of skymet– International weather website
