Wind currents are large-scale movements of air in the Earth's atmosphere. They are primarily caused by the uneven heating of the Earth's surface by the Sun. Warm air rises, creating areas of low pressure, while cooler air moves in to fill the gap, resulting in wind. These currents can vary in speed and direction, influenced by factors such as the Earth's rotation and geographical features. Wind currents play a crucial role in regulating the climate and weather patterns across the globe. They help distribute heat and moisture, affecting ecosystems and human activities. Understanding these currents is essential for predicting weather and studying climate change.
