What force creates wind quizlet?
The pressure gradient force is the driving force behind wind. The Coriolis effect influences wind speed but not wind direction. High pressure systems are usually associated with stormy weather.
What is wind and what generates it?
Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation. Wind is the movement of air caused by the uneven heating of the Earth by the sun. It does not have much substance—you cannot see it or hold it—but you can feel its force.
Do wind belts affect climate?
On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Thus, a wind travelling north from the equator will maintain the velocity acquired at the equator while the Earth under it is moving slower.
What is the name of the winds between 60 and 90 degrees latitude?
Polar Easterlies: From 60-90 degrees latitude.
Does air rise or sink at 60 n s?
60 degrees N & S Latitudes: another area of rising air, not as strong as ITCZ. 90 degrees N & S Latitudes: air sinks over the poles and moves equatorward. Polar Easterlies (in N Hemisphere): air between pole and ~60 degrees N&S latitudes moves equatorward.
Are trade winds hot or cold?
The trade winds blow toward the west partly because of how Earth rotates on its axis. The trade winds begin as warm, moist air from the equator rises in the atmosphere and cooler air closer to the poles sinks.
Is wind gust dangerous?
The winds of 15-25 mph, with gusts of up to 45 mph, may blow around unsecured objects, take down tree limbs and potentially cause power outages. – at 55 to 63 mph, entire trees can be uprooted and considerable structural damage can occur. – above 64 mph, expect widespread structural damage.
What is gush of wind?
A gust or wind gust is a brief increase in the speed of the wind, usually less than 20 seconds. It is of a more transient character than a squall, which lasts minutes, and is followed by a lull or slackening in the wind speed.
What’s the difference between wind and wind gust?
Generally speaking, wind refers to the flow of different gases within a large area. A gust is a sudden increase of the wind’s speed that lasts no more than 20 seconds. This usually occurs when wind speeds reach a peak of at least 16 knots. A wind gust usually comes in 2-minute intervals.
Why are winds gusty?
A wind gust is a sudden, brief increase in the speed of the wind followed by a lull. Gusts at the ground are caused by either turbulence due to friction, wind shear or by solar heating of the ground. These three mechanisms can force the wind to quickly change speed as well as direction.
What wind speed is a breeze?
|1||Light Air||1 to 3 mph|
|2||Light Breeze||4 to 7 mph|
|3||Gentle Breeze||8 to 12 mph|
|4||Moderate Breeze||13 to 18 mph|
