Weather forecast and commonly used weather symbols
2. Clouds with white dots indicate: blizzard, blizzard, etc.
3. Clouds with blue dots indicate: continuous heavy rain, light snow, light showers, etc.
4. Cloud plus lightning means: thunderstorm, thunder and lightning, etc.
Extended information:
-Sunny: The sky has less than 30% cloud cover.
-Overcast: The sky has cloud cover accounting for 90% or more.
-Fog: A large number of tiny water droplets or ice crystals floating in the air near the ground, reducing horizontal visibility to less than 1 km.
-Light rain: daily pre cipitation is less than 10 mm.
-Heavy rain: Daily pre cipitation is 25.0-49.9 mm.
-Thunderstorm: intermittent pre cipitation that comes and goes and is accompanied by lightning and thunder.
-Hail: With the intense vertical movement in cumulonimbus clouds, small hail nuclei repeatedly rise, condense, fall and melt, growing into small ice cubes with alternating transparent layers and falling, which has an impact on crops.
-Freezing rain: Raindrops frozen on the ground on the surface of objects below 0°C, also known as rain (those frozen by fog droplets are called rime).
-Sleet: The temperature near the ground is slightly above 0℃, wet snow or rain and snow fall at the same time.
-Light snow: The daily snowfall (melted into water) is less than 2.5 mm.
-Medium snow: Daily snowfall (melted into water) 2.6-4.9 mm.
-Heavy snow: The daily snowfall (melted into water) reaches or exceeds 5.0 mm.
-Frost: When water vapor condenses into white crystals on the ground and object surfaces with a temperature below 0°C, it is called hoar frost. If the water vapor content is low and there is no frost, it is called black frost. It can cause freezing damage to crops and is called frost.
Strong wind: repre sented by wind arrows, consisting of wind rods and wind feathers. The wind direction pole refers to the direction of the wind and has 8 directions.

Explanation of weather phenomena
Sunny: less than 30% cloud cover
< p>Sunny to cloudy: less than 30% of the sky's cloudiness will account for 30% to 80% of the sky's cloudiness;Cloudy: 30% to 80% of the sky's cloudiness;
Overcast: the sky will be cloudy Cloud cover accounts for 90% or more;
Light (shower) rain: the daily rainfall is less than 10 mm;
Moderate rain: the daily rainfall is 10.1-24.9 mm;
Heavy rain: the daily rainfall is 25.0-49.9 mm;
Heavy to heavy rain: the daily rainfall is more than 50.0 mm;
Thunderstorm: it falls and stops suddenly, accompanied by lightning and thunder. Intermittent pre cipitation;
Light snow: the daily snowfall (melted into water) is less than 2.5 mm;
Medium snow: the daily snowfall (melted into water) is 2.6-4.9 mm;< /p>
Heavy blizzard: the daily snowfall (melted into water) reaches or exceeds 5.0 mm;
Hail: small hail nuclei rise and condense repeatedly with the intense vertical movement in cumulonimbus clouds It falls and melts, growing into small ice cubes with alternating transparent and opaque layers (generally 4-5 layers) and falling;
Frost: Water vapor condenses into white on the ground and surfaces with temperatures below 0°C. What crystallizes is white frost. When there is little water vapor content and no frost, it is called black frost. It is harmful to crops and is collectively called frost;
Fog: refers to a collection of large amounts of water droplets or ice crystal particles suspended in the air close to the ground. When this kind of aggregate reduces the horizontal visibility distance to less than 1,000 meters, it is called fog. When the visibility distance drops to between 1,000 and 10,000 meters, it is called light fog;
Freezing rain: Raindrops freeze below 1,000 meters. On the surface of objects with a temperature of 0°C, it is also called rime (frozen by fog droplets, called rime). It often breaks wires and causes the road to freeze, affecting communications, power supply, transportation, etc.;
Rime pine: Raindrops freeze on surfaces and the ground below 0°C, and are called rain pine (those frozen by fog droplets are called rime). They often fall down and break wires, causing the road to freeze, affecting communications, power supply, Transportation etc.
Weather symbols are graphics or symbols that describe weather conditions and are often used in weather forecasts and meteorological charts. The following are some common weather symbols and their meanings:
1. Sunny: It means that the cloud cover in the sky is less than 30% and the weather is clear.
2. Overcast: It means that the cloudiness in the sky reaches 90% or more and the weather is gloomy.
3. Fog: It means that there are a large number of tiny water droplets or ice crystals floating in the air near the ground, and the horizontal visibility drops to less than 1 kilometer, which will affect transportation.
4. Light rain: means that the daily pre cipitation is less than 10 mm and the weather is light rain.
5. Heavy rain: It means that the daily pre cipitation is between 25.0-49.9 mm, and the weather is heavy rain.
6.Thunderstorm: means bursts of pre cipitation that come and go and are accompanied by lightning and thunder.
7. Hail: It means that with the intense vertical movement in cumulonimbus clouds, small hail nuclei repeatedly rise, condense, fall and melt, growing into small ice cubes with alternating transparent layers and falling, which has an impact on crops.
8. Freezing rain: means raindrops frozen on the ground on the surface of objects below 0℃, also known as rain (frozen by fog droplets, called rime), often falling down and breaking wires, causing the road to freeze. Affecting communications, power supply, transportation, etc.
9. Sleet: It means that the temperature near the ground is slightly higher than 0℃, wet snow or rain and snow fall at the same time.
10. Light snow: means that the daily snowfall (melted into water) is less than 2.5 mm.
11. Moderate snow: Indicates that the daily snowfall (melted into water) is between 2.6-4.9 mm.
12. Heavy snow: means that the daily snowfall (melted into water) reaches or exceeds 5.0 mm.
13. Frost: It means that water vapor condenses into white crystals on the surface of the ground and objects with a temperature below 0°C. It is called hoar frost. If the water vapor content is low and there is no frost, it is called black frost. It will cause freezing damage to crops and is called frost.
14. Low-pre ssure trough and high-pre ssure ridge: repre sent the undulating high-altitude westerly airflow. The trough corresponds to the low-pre ssure trough. The warm air in front of the trough is active, rainy and snowy weather, and the cold air behind the trough controls the windy and cooling weather; the wave crest Corresponding to the high pre ssure ridge, the sky will be clear.
15. Cold front and warm front: It means that the cold front is the front of the cold air. At the junction of the cold and warm air masses, the cold air pushes towards the warm air. There will be strong wind and rain on the cold front, and it will be windy and cooling after the front. On the contrary, it will be cloudy and rainy on the warm front, and it will become cloudy and sunny after the front, and the temperature will rise.
16. Strong wind: repre sented by wind arrows, consisting of wind poles and wind feathers. The wind direction pole refers to the direction of the wind and has 8 directions. The wind plume consists of 3 or 4 dashes and triangles repre senting the force of strong winds, vertically to the right of the end of the wind pole (Northern Hemisphere).
