WIND AND WEATHER
___________________= the condition of Earth’s atmosphere at a particular time and
place.

_______________is an important part of weather.
___________________= air that moves horizontally, or parallel to the ground.

________________________ can differ place to place at the same altitude.

________________________ of the Earth’s surface causes such pressure
differences and causes wind.
Wind moves from an area of ___________ PRESSURE
to and area of _____________PRESSURE.
1) Sunlight ______________ an area of the ground  ground heats the ___________
 warm air ______________  area of ___________ pressure forms.
2) Sunlight heats another area of the ground ____________strongly  Cooler, denser
air ___________  Area of __________pressure forms.
3) Air moves as ____________ across the surface, from higher toward lower pressure.

______________ pressure differences cause a little wind.

LARGE pressure differences cause _______________wind.
Question: How far does wind travel?
Name: ___________________________
Date: _______________
Answer: It varies; some winds die out __________________ & others are ________________________.
_______________ winds travel 1000’s of kilometers in steady patterns and can last for
weeks.

Global winds are caused by uneven heating between the__________________
and the ___________________________________.
Is the area of low pressure created in the equator or the poles?
Is the area of high pressure created in the equator or the poles?
CORIOLIS EFFECT
__________________________= Describes how Earth’s rotation steers winds and
surface ocean currents.
-The Earth rotates ______________________________ at a high speed as viewed
from the North Pole.
- If an object starts at the North Pole and moves toward the equator in a straight-line
path, for example, the object will appear to deflect to the _____________ of its intended
path because the earth is _________________________________ as it moves.
-The Coriolis Effect causes freely moving objects to appear to move to the
_____________ in the Northern Hemisphere and to the left in the Southern Hemisphere.
-The objects are moving ___________________, but the Earth is rotating beneath them,
so they seem to ____________________.

Example of the Coriolis Effect:
-If an airplane flies 500 miles due north, it will not arrive at the city that was due north of
it when it began its journey.
-Over the time it takes the airplane to fly 500 miles, that city moved, along with the Earth
it sits on.
-The airplane will therefore arrive at a city to the west of the original city (in the Northern
Hemisphere), unless the pilot compensates for the change by also veering north.
-The Coriolis Effect an be seen in action in the general ______________________ of
the atmosphere, including _________________and ________________________.
-Does not impact the wind speed, only the wind ___________________.
-The Coriolis Effect impacts objects on a _____________________ (like hurricanes)
and does not generally have a big influence on small scale objects at the earth’s surface.
-___________________________ need the Coriolis Effect to help develop the circular
motion of their circulations.

3) What direction do big storms spin the in the Northern Hemisphere?
4) What direction do big storms spin in the Southern Hemisphere?
5) What direction does Earth spin on its axis?
6) Which spins faster? Points on the equator or points on the poles?
7) If you were standing in Texas and had a magical paper air plane that you threw
straight north, where would it land due to the Coriolis Effect?
8) Where would the paper air plane have landed without the Coriolis Effect?
9) If a magic paper air plane is flying from the equator to the South, which direction
is it deflected to?
10) Is it an area of high pressure or low pressure in the eye of a storm?

the direction of its rotation. Label it (Southern Hemisphere, Clockwise, Eye, High
pressure/Low Pressure).
