Definition
Polar easterlies are a prevailing wind found in the high-latitude regions of the Earth. They blow from the east to the west and are caused by the difference in temperature between the poles and the equator. The polar easterlies are strongest in the winter and weakest in the summer.
Causes
The polar easterlies are caused by the difference in temperature between the poles and the equator. The poles are much colder than the equator, so the air at the poles is denser than the air at the equator. This difference in density creates a pressure gradient, which causes the air to flow from the poles to the equator.
Effects
The polar easterlies have a number of effects on the Earth’s climate. They help to transport heat from the equator to the poles, which helps to moderate the Earth’s temperature. They also help to create the jet stream, which is a band of strong winds that circles the Earth at high altitudes.
Climate change
The polar easterlies are expected to change in response to climate change. The poles are expected to warm more than the equator, which will increase the difference in temperature between the two regions. This will increase the strength of the polar easterlies.

The polar easterlies are also expected to become more variable in response to climate change. This could lead to more extreme weather events, such as cold snaps and heat waves.
The polar easterlies are a vital part of the Earth’s climate system. They help to moderate the Earth’s temperature and transport heat from the equator to the poles. However, they are expected to change in response to climate change. These changes could lead to more extreme weather events.
Jet stream
The jet stream is a band of strong winds that circles the Earth at high altitudes. It is caused by the difference in temperature between the poles and the equator. The jet stream is strongest in the winter and weakest in the summer.
The jet stream has a number of effects on the Earth’s climate. It helps to transport heat from the equator to the poles, which helps to moderate the Earth’s temperature. It also helps to create the polar easterlies, which are a prevailing wind found in the high-latitude regions of the Earth.
The jet stream is expected to change in response to climate change. The poles are expected to warm more than the equator, which will increase the difference in temperature between the two regions. This will increase the strength of the jet stream.
The jet stream is also expected to become more variable in response to climate change. This could lead to more extreme weather events, such as cold snaps and heat waves.
Polar vortex
The polar vortex is a large area of cold air that sits over the North Pole. It is caused by the difference in temperature between the poles and the equator. The polar vortex is strongest in the winter and weakest in the summer.
The polar vortex has a number of effects on the Earth’s climate. It helps to keep the cold air at the poles and prevents it from spreading to the lower latitudes. It also helps to create the jet stream, which is a band of strong winds that circles the Earth at high altitudes.
The polar vortex is expected to change in response to climate change. The poles are expected to warm more than the equator, which will weaken the polar vortex. This could lead to more extreme weather events, such as cold snaps and heat waves.

Frequently Asked Questions
What are polar easterlies?
Polar easterlies are a prevailing wind found in the high-latitude regions of the Earth. They blow from the east to the west and are caused by the difference in temperature between the poles and the equator.What causes polar easterlies?
Polar easterlies are caused by the difference in temperature between the poles and the equator. The poles are much colder than the equator, so the air at the poles is denser than the air at the equator. This difference in density creates a pressure gradient, which causes the air to flow from the poles to the equator.What are the effects of polar easterlies?
Polar easterlies have a number of effects on the Earth’s climate. They help to transport heat from the equator to the poles, which helps to moderate the Earth’s temperature. They also help to create the jet stream, which is a band of strong winds that circles the Earth at high altitudes.How are polar easterlies expected to change in response to climate change?
Polar easterlies are expected to change in response to climate change. The poles are expected to warm more than the equator, which will increase the difference in temperature between the two regions. This will increase the strength of the polar easterlies.What are some other things to know about polar easterlies?
Polar easterlies are strongest in the winter and weakest in the summer. They are also strongest in the Northern Hemisphere than in the Southern Hemisphere.

Answer
(C) The polar easterlies are strongest in the winter and weakest in the summer.
Question 2
The polar easterlies are caused by the difference in temperature between the poles and the equator. The poles are much colder than the equator, so the air at the poles is denser than the air at the equator. This difference in density creates a pressure gradient, which causes the air to flow from the poles to the equator.
Which of the following is not a cause of the polar easterlies?

Answer
(D) The Earth’s rotation is not a cause of the polar easterlies.
Question 3
The polar easterlies have a number of effects on the Earth’s climate. They help to transport heat from the equator to the poles, which helps to moderate the Earth’s temperature. They also help to create the jet stream, which is a band of strong winds that circles the Earth at high altitudes.
Which of the following is not an effect of the polar easterlies?
(A) They help to transport heat from the equator to the poles.
(B) They help to create the jet stream.
(C) They cause the Earth’s temperature to fluctuate.

Answer
(C) The polar easterlies do not cause the Earth’s temperature to fluctuate. They help to moderate the Earth’s temperature by transporting heat from the equator to the poles.
Question 4
The polar easterlies are expected to change in response to climate change. The poles are expected to warm more than the equator, which will increase the difference in temperature between the two regions. This will increase the strength of the polar easterlies.
Which of the following is not a prediction about how the polar easterlies will change in response to climate change?
(A) The polar easterlies are expected to become stronger.
(B) The polar easterlies are expected to become weaker.

Question 5
The polar vortex is a large area of cold air that sits over the North Pole. It is caused by the polar easterlies, which help to keep the cold air in place. The polar vortex can weaken or break down, which can allow cold air to spill down into the lower latitudes.
Which of the following is not a consequence of a weakening or breakdown of the polar vortex?
(A) Cold air can spill down into the lower latitudes.
(B) The jet stream can become wavy or disrupted.
(C) Extreme weather events can occur.
