Local Winds and Global Winds By: Haley Rizzo


Winds are an important part of our world. Wind is the horizontal movement of air from an high area of high pressure to an area of lower pressure. Wind is cause by Unequal heating of earths surface and difference in air pressure. Mots differences in air pressure are caused by unequal heating in earths atmosphere. Wind Vanes are used to determine the direction of wind and wind speed is measured with an anemometer.

Global Winds and Local Winds

Local Winds

local Winds are caused by the unequal heating of Earths surface within a small area. There are two types of Local Winds, Sea breezes, and Land Breezes. Land Breezes occur during the night, and Sea breezes occur during the day but only close to the ocean. They also change direction and speed very often. local Winds form when large-scale winds are weak. Land breezes blow by when the air over the land is cooler than the air air over the sea. Sea breezes blow when unequal heating occurs along the shore of a large body of water. Sea breezes blow only during the daytime and land breezes only blow during the night.

Global Winds

Global winds are winds that blow steadily over long distances. They are created by the unequal heating of earths surface. Global Winds also only occur and travel over very large areas of earth. In Global Winds, there are Global Convection Currents and and the Coriolis Effect. The Global Convection Currents develop from the change of temperatures from the equator to the 2 poles. Global winds also form when most of the sunlight is hitting directly on the Equator.
