Transcript of Wind

Coriolis Effect
makes everything (seem to) go to the right
Earth's rotation moving faster than vehicle in the air
the closer to the poles, the more force
hurricanes
Fast Fact: If an airplane were to stay in one spot, than the pilot (or anyone else on the plane) could see the Earth moving!
Trade Winds, Jet Streams, and the Coriolis Effect
Air Currents
Wind, Westerlies, and Polar Easterlies
Sea and Land Breezes
Thanks for Watching!
Wind
air that is in natural motion parallel to the ground
weather occurs in the troposphere.

Westerlies
Polar Easterlies
located at poles, near westerlies
formed when cold air sinks, moves towards equator.
when meeting warmer air from westerlies, forms polar front
60 degrees, north and south
Trade Winds
point toward the equator
equatorial sides of horse latitudes
25- 30 North and South of the equator
doldrums
Earth rotation
Fast Fact: Trade winds are called trade winds because they help sailors and ships with cargo move from place to place faster.
Jet Stream
high speed stream of air
from west
usually 400kph
10-15k high
Fast Fact: Jet streams were discovered in 1944 when Japanese air balloon bombs were being sent off to reach Europe and ended in Canada.
Sea Breeze
a breeze blowing toward land from the sea
is caused when warm air on the land (low pressure) expands and rises and the cool air over the sea (high pressure) sinks. Then, wind blows and area of high pressure to low pressure, causing wind from the sea towards the land.

Fast Fact: Is also known as onshore breeze.
Land Breeze
Questions?
Comments?
a breeze blowing from the land to the sea
is caused when the cool air on land (high pressure) sinks, and the warm air over the sea (low pressure) rises and expands. Then, the wind blows an area of low pressure to high pressure, causing wind to blow from the land to the sea.
wind from west
effect on sea currents
generally between 30° and 60° latitude
Fast Fact: 3200 BC the Ancient Egyptians invented the sail
Fast Fact: Westerlies, combined with trade winds to help ships travel around Europe.
Fast Fact: Is also known as land wind.
Fast Fact: Polar Easterlies tend to be irregular and weak.
