How are the winds in the northern hemisphere different from winds in the southern hemisphere?

1

The reason why global winds flow from east to west and west to east, but not north to south, or south to north.

In this experiment which beaker would heat up faster?

5

Land and sea breezes are considered _______ winds because they only travel short distances.

Local winds are a result of unequal heating of our _______. Land and water cool off at different rates.

This statement will help you understand breezes "land always _______ ". What this means is that land warms up faster than the water and _______ down faster than water.

This unequal heating results in _______
5


Warm air is less _______ than cold air and will rise and create _______ pressure.

Cold air is more dense than warm air and will _______ and this will create high pressure.

Air will always move from _______ pressure to low pressure.

In other words High to low is the _______ way the atmosphere will go!!!
5

As the Sun rises it begins to warm the _______ in the morning. The land begins to warm up faster than the water, a low _______ system is created over the land because it is warmer (and is rising).

The water is colder and has a _______ pressure, and as a result the wind will blow from the _______ to the land (because high to low is the only way the atmosphere will go).

As a result the wind is named where it is flowing from so this is a sea _______ .
5


At the _______ the beach begins to cool down and the land cools down more _______ than the sea. As a result the _______ pressure is now over the cooler land. The water is _______ and has lower pressure. The wind flows from the higher pressure over the land to the lower pressure over the water. It is flowing from land so it is considered a _______ .

Remember:

"Land Always wins"

"High to low is the only way the atmosphere will go"

Local Winds

Sea Breezes and Land Breezes are 2 types of local winds caused by the unequal heating/cooling of land and water.

Sea Breeze
Occurs when the land is heated up during the day. Warm air rises (low pressure/less dense) & cool air (high pressure/more dense) blows in from the cooler ocean to fill the space.

Land Breeze
At night, the water cools down more slowly than the land. The warm air rises over the water & the cooler air from the land blows out to the ocean to fill in the space.

A) What causes sea breezes and land breezes?__________

B) Tim is sitting on the beach in the middle of the DAY. Which way does the cool breeze blow from? __________

C) Caius takes a boat ride at NIGHT. He feels the cool breeze blow. Where does the cool breeze blow from? __________

Global Winds

Global winds are winds that are flowing from great distances.

Global winds form because the Sun rays have to bend around the sphere shape of the Earth at different angles. At the equator, the Sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles. At the poles, the cooler air sinks and moves back toward the equator.

A) Why do global winds occur? __________

B) What causes warm air to rise? __________

C) What causes wind to blow? __________

D) What can you conclude about prevailing winds from their name? __________

E) What creates the air pressure difference between the equator and the poles? __________
