The poles have a high pressure. I know it has a high pressure but not exactly why.
I think because of the sinking air, the air that got cold. You should know the cells etc.
BUT IT's HIGH PRESSURE.
IMPROVE:
It has to do with the prevailing winds and atmospheric shiftings.
I hope you've heard of prevailing winds. They're the winds that blow constantly in one direction over the entire globe. It's just like how people say that the smoke factories in Ohio are blown north eastwards towards New York. There's a global movement of air that separated into three different cells per North/South hemisphere.
Anyway, the poles have their own prevailing winds cell, and blow westwards, called the polar easterlies. A cell is a continuous circular system of wind, meaning air is blown across the ground, then it rises, goes back over, and is blown across ground again. Air in the 60* latitude rises, moves back towards the poles, then sinks again, which causes all the high pressure. This continuous high pressure also causes the lots of dry air that blows down from the north, as well as the generally sunny (or cloudless, if it's nighttime) skies found in the poles.

Where do polar air masses develop?
Polar air masses develop over cold regions, primarily in the polar areas of the Earth, such as the Arctic and Antarctic. These air masses form when the surface temperature is significantly low, causing the air above to cool and become dense. As a result, polar air masses are characterized by cold temperatures and can influence weather patterns as they move towards lower latitudes.
Why is there a permanent low pressure belt in the sub-polar region?
The permanent low-pressure belt in the sub-polar regions is mainly due to the convergence of cold polar air masses with warmer air masses from lower latitudes. This creates a region of instability, leading to rising air and the formation of cyclones. The Earth's rotation also influences the wind patterns and contributes to the development of the low-pressure system in these areas.
Air masses originate in polar and subtropical?
regions and are identified based on their temperature and humidity characteristics. As they move, they can interact with each other and influence weather patterns. Polar air masses are cold and dry, while subtropical air masses are warm and moist.
Why do air masses tend to travel from polar regions toward the equator?
Air masses tend to travel from polar regions toward the equator due to the Earth's rotation and differences in temperature and pressure. The uneven heating of the Earth's surface causes warmer air to rise at the equator, creating low pressure, while cooler air in polar regions leads to high pressure. This pressure difference drives the movement of air masses in a process known as atmospheric circulation. Additionally, the Coriolis effect influences their paths, causing them to curve rather than move in a straight line.
Continental polar maritime polar continental tropical and maritime tropical are types of?
Types of air masses that are characterized by their temperature and humidity characteristics. Continental polar and maritime polar air masses are cold and moist, while continental tropical and maritime tropical air masses are warm and humid. These air masses determine the weather conditions when they interact with each other.
Do polar air masses have air pressure?
yes
What are cold air masses that form at high latitudes called?
Cold air masses that form at high latitudes are called polar air masses. These air masses originate over the polar regions, such as the Arctic and Antarctic, and bring cold temperatures when they move towards lower latitudes.
Why is there a permanent low pressure belt in the sub-polar region?
The permanent low-pressure belt in the sub-polar regions is mainly due to the convergence of cold polar air masses with warmer air masses from lower latitudes. This creates a region of instability, leading to rising air and the formation of cyclones. The Earth's rotation also influences the wind patterns and contributes to the development of the low-pressure system in these areas.
What directions would polar and tropical air masses move in the southern hemisphere?
In the Southern Hemisphere, polar air masses typically move from the south toward the north, while tropical air masses move from the north toward the south. This is due to the general circulation patterns in the atmosphere, where air flows from high pressure (polar regions) to low pressure (equatorial regions), creating these directional movements.
Air masses originate in polar and subtropical?
regions and are identified based on their temperature and humidity characteristics. As they move, they can interact with each other and influence weather patterns. Polar air masses are cold and dry, while subtropical air masses are warm and moist.
What are the 5 types of air masses?
The five types of air masses are polar, tropical, maritime, continental, and arctic. Polar air masses are cold and dry, tropical air masses are warm and dry, maritime air masses are warm and moist, continental air masses are dry and cold, and arctic air masses are extremely cold and dry.
How are maritime polar and continental polar different?
Continental polar and continental tropical are alike in that they are dry air masses. The different between the two is that the continental polar is a cool air mass while the tropical is a very hot mass of air.
What are polar air masses?
Cold, wet air.
What are the types of air masses?
The 4 major air masses are continental polar (cP), continental tropical (cT), marine polar (mP) and marine tropical (mT). Generally, continental air masses are drier than marine air masses, and polar air masses are cooler than tropical air masses. cT air masses are relatively limited in distribution existing in the south west North America and North Africa.
Why do air masses tend to travel from polar regions toward the equator?
Air masses tend to travel from polar regions toward the equator due to the Earth's rotation and differences in temperature and pressure. The uneven heating of the Earth's surface causes warmer air to rise at the equator, creating low pressure, while cooler air in polar regions leads to high pressure. This pressure difference drives the movement of air masses in a process known as atmospheric circulation. Additionally, the Coriolis effect influences their paths, causing them to curve rather than move in a straight line.
Which type of air mass brings cool humid weather to the West Coast of the United states?
Maritime tropical air masses, Maritime polar air masses, Continental polar air masses, or Continental tropical air masses.
Continental polar maritime polar continental tropical and maritime tropical are types of?
Types of air masses that are characterized by their temperature and humidity characteristics. Continental polar and maritime polar air masses are cold and moist, while continental tropical and maritime tropical air masses are warm and humid. These air masses determine the weather conditions when they interact with each other.
