In the northern plains, it brings rain and causes a change in wind direction. But in the mountains, it triggers snowfall. About India Meteorological Department (IMD) :- Established: 1875. Ministry: Ministry of Earth Sciences. IMD Headquarters: New Delhi. It is the National Meteorological Service of the country. It is the principal government agency in all matters relating to meteorology and allied subjects. Objectives:- To take meteorological observations and provide current and forecast meteorological information for optimum operation of weather-sensitive activities like agriculture, irrigation, shipping, etc. To warn against severe weather phenomena tropical cyclones, duststorms, heavy rains and snow, cold and heat waves,, which cause the destruction of life and property. To conduct and promote research in meteorology and allied disciplines. To provide meteorological statistics required for agriculture, water resource management, industries, oil exploration and other nation-building activities. The IMD uses four colour codes:- Green (All is well): No advisory is issued. (Colour Coded Weather Warning) Yellow (Be Aware): Yellow indicates severely bad weather spanning several days. Orange/Amber (Be prepared): The orange alert is issued as a warning of extremely bad weather with the potential of disruption in commute with road and rail closures, and interruption of power supply.
