What is wind and what causes it to blow?

Warm air, which weighs less than cold air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.

What causes winds to blow stronger?

Strong winds are due to a strong pressure gradient force. A pressure gradient is how fast pressure changes over distance. So, when pressure changes rapidly over a small distance, the pressure gradient force is large. Strong winds almost always result from large pressure gradients.

What causes the wind?

Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation. Differences in atmospheric pressure generate winds. At the Equator, the sun warms the water and land more than it does the rest of the globe.

What affects wind direction and strength?

The speed and direction of the wind is governed by three forces; the pressure gradient force (PGF), the Coriolis Force and friction. PGF is the force produced by differences in barometric pressure between two locations and is responsible for the flow of air from an area of high pressure to an area of low pressure.

What is the main factor that determines the global wind pattern?

What is the main factor that determines the global wind pattern? uneven heating of Earth’s surface by the Sun. Rainforests are found near the equator because of the convergence of the trade winds, which causes increased rainfall.

What determines the direction of the wind blows?

A major factor that determines wind direction is air pressure. Wind travels from areas of high pressure to areas of low pressure. Coriolis effect is the rotation of the earth from west to east, which, generally speaking, causes winds to blow in a counterclockwise or clockwise manner.

What are the factors that affect the wind?

Three of the major factor that affect the direction of wind flow are:- 1) Pressure gradient 2) Rotation of the planet 3) Friction

• Pressure gradient.
• Rotation of the planet.
• Friction. Was this answer helpful? Similar questions. Wind blows in which direction? Easy.
