Why does cold polar air flow toward the equator?
Air decends at the poles and rises at the equuator. The basic part of the weather machine.
What air mass is indicated by composed of cold dry air?
The Continental Polar is composed of cold dry air.
What are the pressure conditions of the air above poles?
Generally the poles are cold places, receiving Sunlight at a low angle or no Sun at all. This means the air above the poles tends to be cooler than the rest of the planet. Cold air is dense so the pressure of the air at the poles tends to be higher than the rest of the planet. Thus air (cold air) tends to flow away from the polar regions along the Earth's surface to be replaced by light warmer air flowing into the poles at a higher level (this air then cools). There is therefore a general flow of warm air north and south towards the poles from the equator and a flow of cold air from the poles towards the equator. This flow of air spreads out the heat from the Sun, warming the poles and cooling the tropics. In detail this overall flow is restricted by the thickness of Earth's atmosphere and several flow cells form to complete the chain causing Earth's climatic zones.
What are cold dry air masses that flow into the US from the interior of Canada called?
It's Continental Polar.
What are the air currents that flow near the north and south poles?
The polar easterlies (also Polar Hadley cells) are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards low-pressure areas within the Westerlies at high latitudes.
Why are air conditioners are usually placed at a higher level rather than at a lower level?
Heat rises, cold falls. Hot air will rise towards the ceiling, while cold air will travel towards the floor. Thus, it's beneficial to have the air conditioning at a higher level to allow the cold air flow downwards.
Which are the characteristics of a maritime polar air mass?
A maritime polar air mass is characterized as a cold and moist air mass.
What are polar air masses?
Cold, wet air.
Identify the air mass indicated by this description composed of cold dry air?
Continental polar is indicated by composed of cold dry air.
Are maritime polar air mass likely to be dry and cold?
Pay close attention to your question. A maritime (meaning oceanic) air mass has moisture, therefore it's not dry. Polar (meaning from the polar region) air mass is cold, therefore it is cold. Hence a maritime polar air mass would be moist and cold...how hard was that?
What is the continental polar air mass?
Cold dry air
What type of air exist in a continental polar air mass?
There are cold and dry air that exists in a continental polar air mass
