When isobars are close together, the wind is stronger
Isobars
The lines on weather maps that show equal air pressure
Isobars
When isobars form a closed loop, the center is called a pressure center
Isobars
Low pressure(L) centers = cloudy and rainy
Isobars
High pressure (H) centers= fair weather
Isobars
The number that appears in the line tells you what the air pressure is on that line
Isobars
Fast moving cold air moves under a slower warm air mass and pushes it up
Cold front
Clouds are formed, high winds, thunderstorms, heavy percipitation
Cold front
Severe weather is short lived
Cold front
Showed by blue triangles
Cold front
A mass of warm air moves toward and over a cold mass of cold air
Warm front
As the warm air is pushed up over the cool air, it cools and forms clouds. Represented by semicircles
Warm front
Two air masses meet but neither goes over or under
Stationary front
Instead, the air masses move side by side along the front
Stationary front
Light winds and mild precipitation
Stationary front
Represented by red semicircles and blue triangles
Stationary front
When a warm air mass gets caught between two cold air masses
Occluded front
Strong winds and heavy precipitation are common
Occluded front
Represented by triangles and semicircles
Occluded
Seasons are caused by the tilt of the earth on its axis. The earth is tilted at 23.5*
Seasons
Solstice occurs twice a year when the sun is at 23.5* south and 23.5* north. Summer solstice = June 21. Winter solstice= December 21
Seasons
Equinox is half way between the solstice-daylight and darkness are equal. Mark the beginning of spring and fall- March 21, September 22
