This project involves collecting weather information from various media sources like newspapers, TV, and radio to understand weather systems. The purpose is to observe how atmospheric pressure variations cause the movement of air from high pressure to low pressure, setting the air in motion as wind.

Newspapers often contain satellite pictures showing areas of cloudiness. By marking these areas, one can infer the atmospheric circulation from the distribution of clouds. The vertical rising of moist air cools it down to form clouds and bring precipitation. Comparing forecasts given in newspapers with TV coverage helps estimate how many days in a week the forecasts were accurate.

Understanding weather systems is crucial as wind redistributes heat and moisture across the planet, maintaining a constant temperature for the planet as a whole. The study of phenomena like El Nino and southern oscillation (ENSO) helps understand large-scale variations in weather that occur over the world, such as heavy rainfall, droughts, and floods in different regions.

Weather information also helps understand severe local storms like thunderstorms and tornadoes. These are of short duration, occurring over small areas but are violent. Thunderstorms are caused by intense convection on moist hot days, characterized by intense updraft of rising warm air and downdraft bringing cool air and rain.

This project work enhances practical understanding of how atmospheric pressure determines when air will rise or sink, and how pressure differences cause atmospheric circulation that affects global weather patterns.
