Air Circulation and Precipitation

Colin S. Austin F.

Intertropical Coverage Zone (ITCZ)• Location- near the equator but varies

throughout the year• Effects on weather- creates seasons

including wet and dry seasons near the equator

Air CirculationSun warms cool air causing it to riseCool air sinks and forms high windsCool air sinks to the groundCool air picks up moisture at the ground

How Stoms FormWhen two air masses of different

temperatures Come togetherSome bring light rain while some bring

heavy snow

Extreme StormsTropical cyclones- storms that forms over

oceans in the tropicsTornadoes- high wind speedsof up to 250 miles per hourHurricane- covers large areas with lower wind speeds thantornadoes

Other Storms and World Precipation Blizzards- severe snow stormRain levels increase near the equatorMore rain occurs there due to the ITCZ winds
