Which direction does air in high preasure areas move.
clockwise and away from the center
Which direction does air in low preasure areas move.
counter clockwise and toward the center
Close spacing of isobars represents what
high wind velocety
as you get closer to the middle in low pressure the pressure _____
decreases
as you get closer to the middle in high pressure the pressure _____
increases
low pressure weather
heat, humid, bad lousy weather, rain, storms
At verry low pressure there could be hurricanes even

barometer
air pressure
wind vane
direction of wind
anemometer
measured wind speed
What weather does high pressure bring
cold, dry weather
as pressure gradient increases _______
wind speed increases
Warm air rises, resulting in a _____ baromic pressure reading
lower
cool air rises, resulting in a _____ baromic pressure reading
Higher
Isobars connect what?
places of equal air pressure values
A strong air pressure gradient will produce ______ conditions
windy
wind blows from _____ to ______
High pressure to low pressure systems
Most, warmer air produces _____ baromic readings
lower
cold, dry air produces _____ baromic readings
higher
Sea breeze
hotter, less dense air over land rises producing L pressure and the colder, denser sunking air over the water produces H pressure
Land breeze
At night the land temprature is lower than the warmer water. Now the H pressure is over the cooler land, and the L pressure caused by the rising air is over the water.
