Planetary Wind and Moisture Belts in the Troposphere

wind

• warm, less dense air rises

• cool, dense air sinks

• large circular patterns of moving air

• movement of air cause by differences in air pressure

Coriolis Effect

• bands of high and low pressure found about every 30 degrees of latitude

• the curving of a path of a moving object from an otherwise straight path due to Earths rotation

• winds that blow from east to west between 60 and 90 degrees latitude in both hemispheres

• narrow belts of strong winds that blow in the upper troposphere

westerlies

• winds that blow from west to east between 30 and 60 degrees latitude in both hemishpheres

• winds that blow from 30 degrees latitude almost to the equator in both hemispheres

• area around the equator where there is very little wind ("dull", "sluggish")

• area around 30 degrees latitude in both hemispheres where there is very little wind
