The term meteorology is referred to the science of weather. The term meteorology has been derived from Greek, in which ‘meteron’ means high in the sky and ‘logos’ means knowledge. Understanding, observation and prediction of weather are the three key aspects of meteorology. Forecasting the weather is the main job of the meteorological department.

The observations vary from measuring temperature with a thermometer or recording the wind speed with anemometer to monitoring the global weather through satellites. The telecommunication channels owing to the growth of modern technology have made it easy for the countries across the world to exchange the weather observations.

Industries like aviation, agriculture, fisheries, shipping, defense, marine activities and tourism greatly depend upon the forecasts done by the meteorological department. The advancement of satellite, computers and various other technologies that are involved in the process of forecasting the weather has led to a substantial progress in the science of meteorology.
