Wind is always named by where it is coming from!

It is called a NORTH wind because it is moving from the north to the south.

What would a wind be named (North or South) if it is blowing from Georgia to Florida?

Most often noticed at the beach!

1. Land heats up faster than water.2. Warm air over land rises.3. Air over water moves to shore.4. Would occur during the day.5. Named a SEA breeze because it comes

from the sea.

Look at these two diagrams. Can you tell which is the land breeze and which is the sea breeze?

1. Blow steadily from the same direction all the time.2. The path is curved because of the Coriolis Effect.

TYPES OF GLOBAL WINDS

A. Polar easterliesB. WesterliesC. Trade winds

Remember! Winds are named according to where originate, or come from.

POLAR EASTERLIESFrom the POLESWind belts that extend from the poles to 60° latitude

Formed from cold sinking air moving from the poles creating cold temperatures

WESTERLIESWind belts found between 30° and 60° latitude

Flow towards the poles from west to east carrying moist air over the Unites States

TRADE WINDSWinds that blow from 30° almost to the equator

Called the trade winds because of their use by early sailors

JET STREAMS

Jet Stream1. Very fast 200-

400 kmh2. Acts like a

conveyor belt3. Goes

completely around the earth.

4. In US, it makes weather generally blow east to west

5. Measured by anemometer

Notice that the jet stream does not stay the same every day. But it is always there!

Notice on this weather map in motion how the rain moves toward the east over time.

SUMMARY Do you know the difference

between sea breeze and land breeze?
