Global Wind Patterns and Cells

The video tutorial explains global winds, their formation, and their impact on Earth's climate. It begins with an introduction to global winds, followed by a demonstration of drawing the Earth with its equator and latitudes. The tutorial then covers pressure zones and temperature effects, explaining how high and low pressures are distributed across the globe. It delves into convection cells, including the Hadley, Ferrel, and Polar cells, and their roles in atmospheric circulation. Finally, the video explores different types of winds, such as trade winds, westerlies, and polar easterlies, detailing their directions and how they are influenced by Earth's rotation.
