Lesson 2 About weather forecasting

• What is weather forecasting?
• Weather forecasting is a prediction of what the
  weather will be like in an hour, tomorrow, next
  week or during a season.
• Weather forecasts, such as
• "Look for cloudy skies with afternoon
• thunderstorms and a high of 380 C"
• provide critical information about the
  weather to come.

Lesson 2 About weather forecasting

• 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
  computers to interpret the weather conditions.

Lesson 2 About weather forecasting

• How weather is predicted?
• Weather forecasting is a very important activity
  of Indian Meteorological Department (IMD).
• IMD provides very comprehensive forecasting
  services for different users.
• IMD has forecasting offices at its 6 Regional
  Meteorological Centers and Meteorological Centers
  at the State capitals.
• In addition it has two major forecasting centers
  at New Delhi and Pune.

Lesson 2 About weather forecasting

• How weather is predicted?
• Indian Meteorological Department (IMD) maintains
  a countrywide network of observational stations
  from where weather reports are received at Pune
  through the Regional Telecommunication Hub based
  at New Delhi.
• With the help of these reports and other
  observations from the globe, the Pune office
  issues the All India Daily Weather Bulletin and
  Weather Forecasts for the entire country.

Lesson 2 About weather forecasting

• How reliable is this weather forecasting?
• Atmospheric conditions change rapidly.
• Hence, even with sophisticated computer models,
  satellite images, and monitoring stations across
  most of the planet, forecasts can be not exact.
• That is, sometimes the weather is more
  predictable than at other times.
