Latitude
Latitudes that receive more direct sunlight are closer to this.
Equator
This pressure system causes cloudy, rainy, or stormy weather.
Low Pressure
When a warm air mass is on its way, we can expect this temperatures to be this.
warmer
Oceans and lakes will make the nearby land this in the winter.
warmer
Clouds during the day do this.
Keep the earth cooler by shading it from the sun.
Temperatures vary with seasons here.
Mid-latitudes
Greater differences between the air pressure in two masses produce this.
Stronger wind
This is created because the land heats up more quickly than the ocean does.
sea breeze
The Gulf Stream moves warm water and air here.
Up the East Coast of the US
Clouds at night do this to the earth.
Insulate it and keep it warmer.
Temperatures here are consistently warm and often humid.
Equator
This is the direction that air moves.
From high pressure to low pressure
Air masses can be moved along quickly by this.
jet stream
The jet stream is a boundary between these two things.
warm and cold air mass
These clouds create an all-day rain.
stratus or nimbostratus
At the equator, this causes greater evaporation and precipitation.
More direct sunlight, heat from the sun
The force of this pushing down on the earth's surface is what we call air pressure.
Earth's atmosphere
This causes higher temperatures, which increases evaporation, and causes precipitation.
increased direct sunlight
The jet stream moves air masses in this direction.
West to east.
These clouds form a low blanket of clouds.
nimbostratus or stratus
In the US, this cardinal direction is generally warmer than the rest.
South
Differences in air pressure is caused by this.
Uneven heating of the earth
This is a result of increased precipitation and increased temperature.
Increased humidity
These winds that affect the US are caused by the rotation of the earth and the sun's uneven heating of the earth.
Prevailing Westerlies
These clouds are responsible for thunderstorms and hail.
