C. Give reasons for the following:
1. There is high pressure in the subtropical regions.
2. Sub-polar regions have a low atmospheric pressure.
3. Westerlies have a greater climatic influence in Western Europe than in North America.
4. Regional and local winds prevail in many areas.
Answers
Explanation:
1) Horse latitudes, subtropical ridges or subtropical highs are the subtropical latitudes between 30 and 35 degrees both north and south where Earth's atmosphere is dominated by the subtropical high, an area of high pressure, which suppresses precipitation and cloud formation, and has variable winds mixed with calm winds.
2)Warm air being light, the air at the Equator rises, creating low pressure. ... In the Subpolar region around latitudes 60° to 65° North and South of the Equator, the rotation of the earth pushes up the bulk of the air towards the Equator, creating a low-pressure belt in this region.
3) "westerlies have a greater climatic influence in western Europe than in North America". ... It is because the west coast is constantly exposed to predominant westerly winds with equable temperature regimes ,this helps it to get abundant precipitation through out the year.
4) There are many reasons behind the prevailing of local winds : There nearness to costal areas. The uneven heating of the land . There location in valleys where inversion of temperature can also cause local winds .
