What is weather forecasting class 7?
By monitoring the atmospheric conditions such as temperature, pressure, humidity, wind speed and wind direction, sunshine, cloud formations, rainfall (or snowfall), etc., it is possible to predict the coming weather in advance. Prediction of weather in advance is called weather forecasting.

Who Started weather forecast?
