Question

How does atmospheric pressure affect wind direction?

Answer 1

Hint: Wind is defined as the moving air that is caused due to the differences in the air pressure within the atmosphere. The air under the high pressure moves towards the low pressure. When the pressure difference is greater, the air flows faster.

Complete step by step answer:
The direction of the pressure is always described from the higher pressure to the lower pressure. The wind speed is controlled by the strength of the pressure gradient. The wind speed is higher when the pressure gradient is stronger.
In general, the wind is caused by the air which flows from high pressure to low pressure. The wind will blow faster when the difference between the high pressure and the low pressure is greater. Hence in the northern hemisphere, the wind blows clockwise under the area of high pressure and blows in the counterclockwise direction under the low pressure.
As the height increases, the wind speed increases.

Note:
1. The atmospheric pressure which is also known as the barometric pressure is defined as the pressure within the atmosphere of the earth. At the sea level, the atmospheric pressure will have an average value of one atmosphere and as the altitude increases, it gradually decreases.
2. Pressure can also be defined as the force that exerts a unit area whereas the atmospheric pressure is the equivalent to the weight of the air within its atmosphere.
3. The temperature, altitude, moisture, Gravitation of Earth, Rotation of the Earth, etc, are the factors that affect the air pressure.
