Convection Currents 9/30

Remember high pressure systems always moves toward the low pressure systems! This is a picture of a land breeze.
At night time air over the land is cooler and creates an area of high pressure. The cool air moves toward the water, producing a land breeze. Air over water is warmer and creates an area of low pressure.
Just the opposite happens during the day. Air over water is cooler and creates an area of high pressure. The cool air moves toward the land, producing a sea breeze. As this warm air rises (as is the case when it runs in to the coast range here in Oregon) it creates an area of low pressure over the land.
