What does it mean that the weather forecast of apples is like the wind?

If the sky is divided into 10 parts and the cloud cover is less than 30%, it is sunny. Cloudy: The amount of clouds in the sky accounts for 3-80%, and it is cloudy most of the day (night) with little or no clear sky. Cloudy day: the amount of clouds in the sky accounts for 90% or more, and there will be a lot of clouds all day (at night). According to other meteorological conditions, it may rain.

Light rain: 24-hour cumulative precipitation 0.1-9.9mm Moderate rain: 24-hour cumulative precipitation10.0-24.9mm Heavy rain: 25.0-49.9mm.

Extended data sunny day: the sky is less than 30% cloudy.

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

Fog: A large number of tiny water droplets or ice crystals float in the air near the ground, and the horizontal visibility drops to less than 1 km.

Light rain: the daily precipitation is less than10mm.

Heavy rain: the daily precipitation is 25.0-49.9mm..

Thunderstorm: Intermittent precipitation accompanied by lightning and thunder.

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 with transparent layers, which have an impact on crops.

Freezing rain: raindrops freeze on the ground below 0℃, also called rain song (frozen by fog drops, called rime).

Sleet: The temperature near the ground is slightly higher than 0℃, and wet snow or rain and snow drop at the same time.

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 snow: the daily snowfall (melting into water) reaches or exceeds 5.0 mm.

Frost: When the temperature is lower than 0℃, water vapor condenses into white crystals on the ground and the surface of objects to form frost. If there is little water vapor and no frost, it is said that black frost has freezing damage to crops, which is called frost.

Strong wind: expressed by wind vector, consisting of wind mast and wind plume. The wind pole refers to the direction of the wind, with eight directions.
