Essay On Wind Generation

1. Wind generation

Wind results from the movement of air due to atmospheric pressure gradients. Wind flows from regions of upper pressure to regions of lower pressure. The more astronomically immense the atmospheric pressure gradient, the higher the wind speed and thus, the more preponderant the wind power that can be captured by wind energy converting machinery.

The generation of wind is intricate due to a number of factors. Among them, the most consequential factors are uneven solar heating, the Coriolis Effect due to the earth’s self-rotation, and local geographical conditions.

1.1 Uneven solar heating

Uneven radiation on the earth’s surface is the most significant of all factors. The unevenness of the solar heating are often attributed to four reasons.

First, the world is a sphere revolving around the sun within the same plane as its equator. As a result of the surface of the globe being perpendicular to the trail of the sunrays at the equator but parallel to the sunrays at the poles, the equator receives the best quantity of energy per unit space, with energy dropping off toward the poles. Thanks to the spatial uneven heating

It’s the lean of the earth’s axis throughout the revolution round the sun that leads to cyclic uneven heating, inflicting the yearly cycle of seasonal weather changes.

Third, the earth’s surface is roofed with differing types of materials like vegetation, rock, sand, water, ice/snow, etc. each of those materials has totally different absorption rates to radiation, resulting in hot temperature on some areas (e.g. deserts) and low temperature on others (e.g. iced lakes), even at an equivalent latitudes.

The fourth reason for uneven heating of radiation is caused by the earth’s geography surface. The different heights of the lands such as mountains, valleys, hills, etc. lead to totally different radiation on the sunny and shady
