Extreme Weather Extreme Weather Extreme weather, which includes hurricanes, tornadoes, and droughts has a huge impact on society. Weather is a product of the interrelationship between between oceanic and atmospheric processes. Weather refers to the condition in the atmosphere at a paricular time and place. We describe weather with quantities like temperature, atmospheric pressure, humidity, percipitation and wind velocity.
Climate refers to the average weather characteristics in a given region.
Climate is an average that describes the expected conditions on time scales of years or centuries. The World's climate is classified using the Koppen classification scheme. The atmosphere transfers heat via convection, or the motion of mass. Hot material rises, while cold gases sink. However, this minor component plays an extremely important role in cycling water around the globe.
