Difference between subtropical high pressure and polar high pressure.
Answers
Subtropical high, one of several regions of semipermanent high atmospheric pressure located over the oceans between 20° and 40° of latitude in both the Northern and Southern hemispheres of the Earth. ... In both hemispheres, subsidence is greater on the eastern sides of the highs.
The polar highs are areas of high atmospheric pressure around the north and south poles; the north polar high being the stronger one because land gains and loses heat more effectively than sea. ... Air flows outwards from the poles to create the polar easterlies in the arctic and antarctic areas.
Answer:
Sub tropical high pressure belt The hot air ascending from the equatorial low pressure belt cools gradually and sub-sides at the sub tropical zone due to the rotation of the earth.
Sub polar low pressure belt - Though the cold air remains close to a the earth, the air is thrown up due to the rotation of the earth. As a result, low pressure is experienced all along the sub polar region. Westerlies.
