What is the weather like?
① Sunny day: It means that the amount of clouds in the whole sky is less than 30% (that is, 30%).
② Cloudy: It refers to the sky condition when there are 4-70% medium-low clouds or 6- 10% high clouds in the sky.
③ Partly cloudy: it refers to the sky condition when there are 65,438+0-3% medium-low clouds or 4-50% high clouds in the sky.
④ Cloudy day: It is a weather phenomenon that the sky is dark and the clouds are densely covered, or even if there are gaps in the clouds (accounting for more than 80% of the total cloud amount), the sky still feels dark, and occasionally weak sunshine can be seen from the gaps in the clouds.
⑤ Fog: refers to a visible aggregate of a large number of tiny water droplets (or ice crystals) suspended in the atmosphere near the ground.
⑥ Cloud amount and cloud height: refers to the percentage of clouds covering the sky; Cloud height refers to the vertical distance from the bottom of the cloud to the ground of the station.
Extended data:
The only difference between fog and clouds is whether they touch the ground or not. Fog greatly reduces the horizontal visibility of the ground. According to the regulations of the International Meteorological Organization, when the visibility drops below 1 km, it is called fog.
Snowfall is divided into light snow, medium snow, heavy snow, blizzard and blizzard according to snowfall. Among them, blizzard is the snow with high snowfall intensity (the horizontal visibility distance is less than 500m during snowfall or the snowfall within 24 hours is greater than15 mm); Blizzard, also known as blizzard, is a weather phenomenon that strong winds carry a lot of snow and it is impossible to judge whether there is snowfall at that time, and the horizontal visibility is less than 1km.
