Explanation of weather phenomena

Sunny day: the cloud cover in the sky is less than 30%.

Sunny to cloudy: the sky cloud cover is less than 30%, and the sky cloud cover accounts for 3-80%;

Cloudy: the sky clouds account for 3-80%;

Yin: the amount of clouds in the sky accounts for more than 90%;

Light rain: the daily rainfall is less than10 mm;

Moderate rain: daily rainfall10.1-24.9mm;

Heavy rain: the daily rainfall is 25.0-49.9 mm;

Heavy rain: the daily rainfall is more than 50.0 mm;

Thundershower: intermittent precipitation accompanied by lightning and thunder;

Light snow: the daily snowfall (melting into water) is less than 2.5 mm;

Medium snow: the daily snowfall (melting into water) is 2.6-4.9 mm;

Heavy snowstorm: the daily snowfall (melting into water) reaches or exceeds 5.0 mm;

Hail: With the violent vertical movement in the cumulonimbus cloud, small hail nuclei repeatedly rise, condense, fall and melt, and grow into small ice cubes (usually 4-5 layers) alternating with transparent layers and opaque layers.

Frost: When the temperature is lower than 0℃, water vapor condenses into white crystals on the ground and the surface of objects, resulting in hoarfrost. When the water vapor content is low and there is no frost, it is called black frost, which has freezing damage to crops and is collectively called frost.

Fog: refers to a large number of water droplets or ice crystal particles attached to the stratum and suspended in the air. It is called fog when the horizontal visual distance drops below 1000m, and light fog when the visual distance drops between 1000m and 1000m;

Freezing rain: raindrops freeze on the ground below 0℃, also called rain storm (frozen by fog drops, called fog storm), which often falls off the power line, freezing the road surface and affecting communication, power supply and traffic;

Fog pine: raindrops freeze on the surface and ground below 0℃, which is called rain pine (if frozen by fog drops, it is called fog pine). It often falls off the power line, freezes the road surface, and affects communication, power supply and traffic.
