What is weather forecasting?

•Weather forecasting is a prediction of what theweather will be like in an hour, tomorrow, next weekor during a season.

• Weather forecasts, such as:

"Look for cloudy skies with afternoonthunderstorms and a high of 380 C"

provide critical information about the weather tocome.






Modules Lessons


How weather is predicted?

• Weather forecasters collect data on atmospheric

conditions, including temperature, humidity,pressure, wind speed, and its direction etc.

• High-speed computers, meteorological satellites,and weather radars are tools used to collect the

weather data.

• Such data are fed into the sophisticated computersto interpret the weather conditions.






Modules Lessons



• Weather forecasting is a very important activity

of Indian Meteorological Department (IMD).

• IMD provides very comprehensive forecastingservices for different users.

• IMD has forecasting offices at its 6 RegionalMeteorological Centers and Meteorological

Centers at the State capitals.• In addition it has two major forecasting centers

at New Delhi and Pune.






Modules Lessons



• Indian Meteorological Department (IMD)

maintains a countrywide network of observationalstations from where weather reports are receivedat Pune through the Regional TelecommunicationHub based at New Delhi.

• With the help of these reports and otherobservations from the globe, the Pune officeissues the All India Daily Weather Bulletin andWeather Forecasts for the entire country.






Modules Lessons


How reliable is this weather forecasting?

• Atmospheric conditions change rapidly.

• Hence, even with sophisticated computermodels, satellite images, and monitoringstations across most of the planet, forecastscan be not exact.

• That is, sometimes the weather is morepredictable than at other times.
