Atmospheric waves are disturbances in the atmosphere that can occur in various forms, such as sound waves, gravity waves, and electromagnetic waves. These waves are generated by factors like wind, temperature changes, and the Earth's rotation. They play a crucial role in weather patterns and can influence climate by redistributing energy and moisture. One common type of atmospheric wave is the Kelvin wave, which is associated with the El Niño phenomenon. These waves can travel long distances and affect global weather systems. Understanding atmospheric waves helps meteorologists predict weather events and improve climate models.
