You are watching: What has the greatest effect on wind speed
Air temperature varies between day and also night and from season to season early to changes in the heater Earth"s atmosphere. Since of the sun"s warming effect, over there are much more winds during the day. Wait masses also differ in temperature. A heat front precedes a heat air mass. Heat air is less thick than cold air, so heat air rides up and over the cold air, bring about winds. Converselt, a cold front, the leading edge of a cold wait mass, likewise creates wind.
Air pressure is the weight of a obelisk of air getting to the peak of the atmosphere from the ground. Air push decreases with enhancing altitude and fluctuates throughout Earth"s surface ar due to distinctions in soil elevation. At the Earth"s surface, wind blows horizontally indigenous high press to low pressure areas. The rate is figured out by the rate of air press change, or gradient, in between the two press areas. The greater the pressure difference, the much faster the winds.
Centripetal force increases air speed and also influences the direction that wind flowing approximately the center of the circulation. This acceleration creates a pressure at ideal angles come the circulation of the wind and also inward toward the center of the rotation, such as low and also high pressure systems. The winds in a low push system, dubbed cyclones, punch in a counterclockwise and also inward direction in the northern Hemisphere. Winds in high pressure systems, well-known as anticyclones, punch in a clockwise and also outward direction in the north Hemisphere.

The rotation of planet on that axis causes winds to change direction, creating what are referred to as the prevailing winds. This wind shift, known as the Coriolis effect, reasons winds in the northern Hemisphere to transition to the right and winds in the southern Hemisphere to transition to the left. The trade winds, likewise called easterlies, blow near the equator between 30 levels north latitude and also 30 levels south latitude. North of the equator, these trade winds punch from the northeast. Whereas they blow from the southeast south of the equator. The westerlies of the center latitudes punch from the southwest in the northern Hemisphere and also from the northwest in the southerly Hemisphere. The polar winds prevail in the Arctic and Antarctic, indigenous the latitude that 60 degrees to the poles. These winds blow from the northeast in the Arctic and also from the south east in the Antarctic.
