Weather Phenomena Types - TSV

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.

code	slug	name	description	category
H-01	rain	Rain	Precipitation in the form of liquid water droplets falling from the atmosphere.	Hydrometeor (Precipitation)
H-02	snow	Snow	Precipitation in the form of white, soft ice crystals.	Hydrometeor (Precipitation)
H-03	thunderstorm	Thunderstorm	Large-scale electrical discharge occurring within cumulonimbus clouds.	Electrometeor
H-04	tornado	Tornado	A violently rotating column of air extending from a cumulonimbus cloud.	Wind Phenomenon
P-01	rainbow	Rainbow	An optical phenomenon forming an arc caused by refraction and reflection of light in water droplets.	Photometeor (Atmospheric Optical Phenomenon)
P-02	halo	Halo	A ring of light around the Sun or Moon caused by refraction and reflection of light in ice crystals.	Photometeor (Atmospheric Optical Phenomenon)
P-03	mirage	Mirage	A phenomenon where objects appear distorted due to refraction of light by atmospheric temperature gradients.	Photometeor (Atmospheric Optical Phenomenon)
H-05	hail	Hail	Precipitation in the form of ice pellets or lumps with diameter of 5mm or more.	Hydrometeor (Precipitation)
H-06	fog	Fog	A phenomenon where visibility is reduced by tiny water droplets suspended in the atmosphere near the ground.	Hydrometeor (Suspension)
L-01	haze	Haze	A visibility impairment phenomenon caused by fine particles in the atmosphere.	Lithometeor
