Winds that are created by local differences in geography such as oceans or mountains

What is a local breeze?

Wind that begins with high pressure over the land and moves toward low pressure over the ocean

What is a land breeze?

Wind that starts with high pressure over the ocean and moves toward low pressure over land

What is a sea breeze?

Wind that begins with high pressure at the mountain top and moves toward the low pressure in the valley below

What is a mountain breeze?

Wind that starts as high pressure in the valley and moves toward the low pressure on the mountain top

What is a valley breeze?

The properties of this are determined by the part of the Earth’s surface over which it forms

What is an air mass?

Name the type of front:

What is a warm front?

The kind of front that forms when a warm air mass is forced up over a cold air mass

What is warm?

Name two things that characterize air masses

What is moisture content and temperature?

What is continental?

Winds found between 90º and 60º latitude

What is polar easterlies?

Winds found at 30º latitude

What is horse latitudes?

Winds found at the equator

What is the doldrums?

Prevailing winds of the United States that are found b/w 30 and 60° latitude

What are westerlies?

Winds that are found between 0º & 30º latitude

What are the trade winds?

An instrument used to measure temperature

What is a thermometer?

Sensitive instruments used to measure atmospheric pressure

What are barometers?

The instrument that measures the amount of water vapor in the air

What is the psychrometer?

An instrument which measures wind speed

What is a anemometer?

The instrument that measures wind direction and is shaped like a funnel

What is a wind sock?

The amount of water vapor in the air

What is humidity?

How most water gets into the atmosphere

What is evaporates?
