Temperature, rainfall, wind, cloud and atmosphere pressure are the main factors that influence weather patterns across the world. Wind is caused by the unequal heating of the Earth’s surface. When the air above a certain region becomes warm and light, it rises and the heavier cool air sweeps across from another area to take its place. This movement of air is called wind. Atmospheric pressure also affects the movement of wind, which always flows from a region of high pressure of that of low pressure. The difference in pressure between the two area determines the speed with the wind blows. If there is a small difference, we feel a breeze. If te difference is large, it leads to a storm. If the wind is flowing over a large water body such as a sea, it can pick up moisture and carry clouds and rain with it. Low pressure usually means stormy waether and rain, while high pressure usually means lots of sun and not much wind. There are other factors, such as the ocean currents created by the Earth’s rotation, which also influence weather.

The wind always blows from an area of high pressure to an area of low pressure.
