What are the types of weather classifications?

Weather phenomena refer to some physical phenomena that occur in the atmosphere and on the ground. Including pre cipitation phenomena, ground condensation phenomena, visual range weather phenomena, lightning obstacle phenomena, thunder and lightning phenomena and other phenomena, etc. These phenomena are all produced under certain weather conditions. In ground meteorological observations, various weather phenomena are repre sented by unified special symbols.
1. Precipitation phenomenon: According to the form of pre cipitation, it is divided into 11 types. Liquid pre cipitation includes rain, drizzle, and showers. Solid pre cipitation includes snow, ice particles, rice snow, snow showers, graupel, hail, and mixed Types of pre cipitation include sleet, showers of sleet, etc. In addition, according to the nature of pre cipitation, there are three types: fractional pre cipitation, continuous pre cipitation and intermittent pre cipitation.
2. Ground condensation and freezing phenomena: including dew, frost, rime, and rain.
3. Visual range obstruction phenomena: including fog (fog, heavy fog, dense fog); light fog; blowing snow; snowstorm; smoke screen; haze; sandstorm (sandstorm, strong sandstorm, super sandstorm); blowing sand; Floating dust.
4. Thunder and lightning phenomena: thunderstorms, lightning, aurora.
5. Other phenomena: strong winds, squalls, tornadoes, dust devils, ice needles, snow and ice.

Types of weather

Weather describes the atmospheric conditions at a specific moment, including temperature, humidity, wind speed, wind direction and Sky conditions, etc. There are many types of weather, which can be classified according to different meteorological conditions and characteristics. The following are some common weather types:

1. Sunny day

Sunny day refers to weather conditions with clear sky and no clouds or only a few clouds. At this time, the sun is shining and the temperature is high, making it suitable for outdoor activities.

2. Cloudy

Cloudy weather refers to a situation in which the sky is covered by clouds to a high degree. In this case, the sun shines through the clouds onto the ground, and there may be localized rainfall or showers.

3. Cloudy days

Cloudy weather is characterized by thicker clouds in the sky, blocking the sunlight, resulting in less solar radiation received by the ground. At this time, it may feel a little cooler and may be a sign of impending rain.

4. Rainy days

Rainy days are pre cipitation in the sky, including light rain, moderate rain, heavy rain, heavy rain, etc. During rainy days, clouds accumulate a large amount of moisture and fall to the ground, which may affect traffic and people's travel plans.

5. Snowy day

Snowy day refers to the condition of snowfall in the sky. Snowflakes fall to the ground and form snow, which affects temperature, traffic, etc. Snow days are divided into different levels such as light snow, heavy snow, and blizzard.

6. Other special weather

In addition to the above common weather types, there are also some special weather phenomena, such as haze, sandstorms, thunderstorms, Tornadoes etc. These weather phenomena have a great impact on people's production and life, and special attention needs to be paid to weather forecasts for pre vention.

In general, there are various types of weather, and each type of weather has its specific meteorological characteristics and effects. Understanding the characteristics of different weather helps us protect and respond to weather conditions.

1. Sunny day: A clear sky with no clouds or only a few clouds, and the sun shines through the gaps in the clouds. Sometimes, thin upper-level clouds do not block the sunlight and can be considered a sunny day.
2. Cloudy weather: When there are medium or low-level clouds and high-level clouds covering 4/10 to 7/10 of the sky, or only high-level clouds cover more than 6/10 of the sky, we call it cloudy.
3. Cloudy day: When the middle and low-level clouds cover more than 8/10 of the sky area, it is difficult for sunlight to penetrate the clouds and the sky looks dark. This is a cloudy day.
4. Night: Night usually refers to the period after the sun goes down and before sunrise. At this time, the sky is usually dark and the stars and moon may be visible.
5. Snowy days: Snowy days refer to weather conditions in which pre cipitation contains ice crystals in the form of snowflakes. Light snow, moderate snow and heavy snow are distinguished according to differences in visibility and snowfall.
6. Fog: Fog is a collection of large amounts of water droplets or ice crystals suspended in the air near the ground. When the horizontal visibility drops below 1,000 meters, we call it fog; if it is between 1,000 and 10,000 meters, it is called light fog.
7. Rainfall: light rain, moderate rain, heavy rain and heavy rain are classified according to the amount of rainfall within 24 hours, ranging from less than 10.0 mm to more than 50.0 mm.
8. Thunderstorm: A thundershower is a shower accompanied by thunder and lightning. It is characterized by sudden rainfall, large changes in intensity, and usually a short duration.
9. Hail: Hail is a kind of solid pre cipitation with a diameter greater than 5.0 mm, consisting of transparent and opaque layers, which may cause damage to crops and buildings.
10. Freezing rain: Freezing rain refers to raindrops freezing on the surface of objects below 0°C, forming an ice layer, which may affect transportation and communication facilities.
11. Sleet: Sleet is a weather phenomenon in which raindrops and wet snow fall at the same time. It usually occurs in an environment with a temperature slightly higher than 0℃.
12. Snowfall: Light snow, moderate snow and heavy snowfall are distinguished based on snowfall amount and visibility, reflecting the intensity and coverage of snowfall.
