WIND IN THE ATMOSPHERE

THE MOVEMENT IN THE AIR

• Air moves from areas of higher pressure toward areas of lower pressure which creates wind
• If the air travels fare enough north, it will have traveled far there east than a point on the ground beneath it. As a result, the air appears to follow a curved path
• Coriolis effect is the apparent curving of the path due to earths rotation

GLOBAL WINDS

• Pressure belts at every 30 degrees of latitude and Coriolis effect produce pattern of calm area and wind systems
• Polar easterlies, westerlies, trade winds
• Jet steam are narrow belts of high-speed wind that blow from the west to east

LOCAL WINDS

• Sea breeze is cold
• Land breeze is warm
• Valley Breeze is warm
• Mountain breeze is cold
