Answer to Question #6666 in Molecular Physics | Thermodynamics for Dania
how the winds currents are generated ? explain.
Wind is caused by pressure differences in regions of air, and the pressure differences are due primarily to temperature fluctuations, and humidity. Areas that are hotter than their surroundings are at a higher pressure, and air moves from high pressure to low pressure. Hot air also tends to form near the ground, where the earth and plants and water trap solar energy and radiate heat into the air. The hot air rises, and also helps create wind.
