The main factor is the high and low pressure cells. Air moves from high to low pressure cells. This air movement is affected by the coriolis effect, which causes highs to spin anticlockwise and lows to spin clockwise (in the Southern Hemisphere, in northern hemisphere is opposite). If you have a look at these systems on a weather map, and draw arrows representing the direction of air flow, you can see what direction wind is going.

Another factor is mountains. These can deflect the normal air flow. For example, in North America, the wind cannot pass the mountains on the western side of the continent. Instead of the wind going in its normal fashion, it is deflected around the mountain chain, and leads the prevailing wind in the north of the continent to be a nor-easter, which leads to the cold winter temperatures there.

How is wind direction determined and what factors influence it?

Wind direction is determined by the direction from which the wind is blowing. Factors that influence wind direction include the rotation of the Earth, temperature differences, pressure systems, and local geography.


What two factors determine the wind that might affect a baseball game?

Both intensity and speed determine how wind affects a baseball game. If the wind is intense, it will slow down not only the pitches but the returns, and if it is fast it can make the ball go farther.


What are three factors that control the path that a surface current?

The three factors that control the path of a surface current are wind direction, the Earth's rotation (Coriolis effect), and the shape of the coastline or the presence of land masses. These factors influence the direction and strength of surface currents in the ocean.


How does wind direction affect moisture content?

Wind direction is the direction which the wind blows. If the wind direction is coming from an arid region, such as a desert, the air will be dry and moisture content will be low. If the wind direction is coming from an ocean, lake, or tropical area, the air will have a higher moisture content.


What is wind direction of the wind in Virginia?

The prevailing wind direction in Virginia is from the west, with variations based on local geography and weather patterns. Wind direction can change throughout the day due to factors such as temperature, pressure systems, and the proximity to bodies of water. It is best to check real-time weather forecasts for specific wind direction information in Virginia.

What 3 factors affect the height length and period of a wave?

The three main factors that affect the height, length, and period of a wave are wind speed, the duration of time the wind has blown in a certain direction (fetch), and the distance over which the wind has blown (fetch length). These factors influence the energy transfer from the wind to the water surface, determining the characteristics of the resulting waves.

What are wind factors?

Wind factors are variables that influence the speed, direction, and intensity of wind. These factors include pressure gradients, temperature variations, and the Earth's rotation. Other factors, such as local topography and surface roughness, can also affect wind patterns.

What factors affect the wind pollination?

Factors that affect wind pollination include wind speed, direction, and consistency, as well as the size, shape, and height of the plant's reproductive structures such as flowers or cones. Weather conditions, such as humidity and temperature, can also influence the effectiveness of wind pollination. Additionally, the presence of barriers or distance between plants can impact the ability of pollen to be dispersed.
