Weather Phenomena Types - INI

Weather phenomena are classified into four main categories in the World Meteorological Organization's International Cloud Atlas: Hydrometeors, Lithometeors, Photometeors, and Electrometeors. These classifications systematically organize all atmospheric phenomena observed in the atmosphere and are widely used for weather observation, forecasting, and research. They include various weather phenomena closely related to our daily lives, such as precipitation, optical phenomena, and electrical phenomena.
