What are the weather phenomena I know?

Rain: Droplet-like liquid precipitation, which can be clearly seen when falling, and its intensity changes slowly. Falling on the water will cause ripples and splashes, and falling on the ground will leave wet spots. Torrential rain: liquid precipitation with sudden stop and great intensity change, sometimes accompanied by thunderstorms.

Mao Mao Rain: Dense, tiny and very uniform liquid precipitation, whose descending situation is difficult to distinguish. It seems to float in the air with the weak movement of air, and slowly fall, with a moist feeling on the face and no ripples on the water surface, but it is evenly wetted on the dry ground without wet spots on the ground.

Snow: solid precipitation, mostly white opaque star-shaped and hexagonal flaky crystals, with six branches, often falls slowly and the intensity changes slowly. When the temperature is high, it often falls in droves.

Shower: the phenomenon of solid precipitation in weather phenomena. Snowfall with short duration, sudden start and end and great intensity change.

Sleet: Semi-melted snow (wet snow), or rain and snow fall at the same time.

Shower sleet: sleet that suddenly starts and stops and changes greatly in intensity.

Graupole: the phenomenon of solid precipitation in weather phenomena. It is composed of white opaque spherical or conical particles, with a diameter of about 2~5 mm, and often falls in an array. When it falls on hard ground, it often bounces and is brittle and fragile.

Snow particles: solid precipitation in weather phenomena. It is composed of white opaque oblate ice particles with a diameter less than 1 mm, and does not rebound when falling on hard ground.

Ice particles: also known as ice pills. Solid precipitation in weather phenomena. It is composed of transparent balls or irregular particles with a diameter less than 5 mm, and it is hard in texture and will rebound when it falls on the hard ground. Sometimes there is still unfrozen water in it, and when it is broken, only the broken ice shell is left.

Hail: Hard spherical, conical or irregular solid precipitation with opaque inner core and transparent outer layer, or composed of transparent and opaque ice layers. The size varies, and the large diameter can reach tens of millimeters. Often accompanied by thunderstorms.

Dew: one of the condensation phenomena on the ground. When the temperature is higher than freezing point, water vapor condenses on the ground and ground objects. It is easy to form at night.

Frost: one of the ground condensation phenomena. When the temperature is below freezing point, water vapor condenses on the ground and ground objects, forming white and brittle ice crystals or ice beads frozen by dew. It is easy to form when the wind is light and the clouds are light at night.

Rime: one of the ground condensation phenomena. Water vapor in the air condenses directly, or supercooled water droplets freeze directly on milky white ice crystals. It is usually a hairy needle or particle with uneven surface. This structure is fragile and easy to collapse in an earthquake.

Glaze: one of the ground condensation phenomena. Hard ice layer formed by direct freezing after supercooled raindrops hit low-temperature (0~-3℃) ground objects. Transparent or frosted glass, smooth or slightly convex. Mainly produced in the windward side.

Fog: An obstacle to sight distance. When the air near the ground is cooled under the conditions of sufficient moisture, light breeze and stable atmosphere, the moisture in the air condenses into tiny water droplets suspended in the air, making the horizontal visibility of the ground less than 1.0 km. It is divided into three grades: 0.5km ≤ visibility.

Mist: formerly known as "haze". A disorder of visual range. The thin gray fog curtain composed of tiny water droplets or hygroscopic particles makes the horizontal visibility between 1 ~ 10 km.

Visual field disturbance phenomenon. Strong wind blows up snow flakes (snowflakes and snow particles) on the ground, making the horizontal visibility less than 10.0 km.

Blizzard: commonly known as "blizzard". A disorder of visual range. A large amount of snow was rolled up by strong wind and moved with the wind, which made the horizontal visibility less than 1.0 km, and it was impossible to judge whether there was snowfall in the sky at that time. When it happens, the cold wind blows hard, burying roads and often causing disasters.

Smoke screen: a visual distance obstacle. There is a lot of smoke in the air, which makes the horizontal visibility less than 10.0 km. The sky over cities and industrial and mining areas is black, gray or brown, and you can smell smoke when it is thick.

Haze: a sight distance obstacle phenomenon. A large number of extremely fine dry dust particles are uniformly suspended in the air, and the air is turbid, and the horizontal visibility is less than 10.0 km. Make bright objects in the distance red and yellow, and make dark objects blue. When the visibility is less than 3 kilometers, it becomes a disastrous weather.

Sand-dust storm: also known as "dust storm, dust storm". A dusty weather. Strong winds raise dust on the ground and make the air turbid, and the horizontal visibility is less than 1 km.

Sand blowing: a dusty weather. The wind blows up the dust on the ground, making the horizontal visibility between 1 ~ 10 km.

Floating dust: a dusty weather. Most of them occur after sand blowing or sandstorm. When there is no wind or the average wind speed is less than 3m/s, a lot of dust floats in the air, which makes the horizontal visibility less than10km.

Thunderstorm: ① Local storm caused by strong convective cumulonimbus clouds accompanied by lightning and strong formation precipitation. (2) In ground observation, it only refers to the weather phenomenon accompanied by lightning, sometimes only thunder is heard, but lightning is not seen.

Lightning: a strong discharge phenomenon in the atmosphere accompanied by luminescence. According to the position in the air, it can be divided into three categories: cloud, cloud and cloud. According to the different shapes of lightning channels, they can be called linear, banded, flaky, spherical, forked, rocket-shaped, beaded lightning and so on.

Aurora: charged particles from the sun (solar wind) enter the earth's magnetic field, pass through the upper atmosphere near the north and south poles of the earth, collide and excite atmospheric atoms, and produce gorgeous brilliance at high altitude. What appears in the South Pole is called Southern Lights, and what appears in the North Pole is called Northern Lights.

Gale: A disastrous weather. Influenced by strong weather processes such as cold front and tropical storm, the wind force in the near-surface layer reaches above 8 (average wind speed 17.2~20.7 m/s).

Squall line: refers to the narrow strong wind belt before the strong cold front or the cumulonimbus cloud. When crossing the border, the wind speed suddenly increases, the wind direction suddenly changes, and the meteorological elements suddenly change, often accompanied by precipitation.

Tornado: Also known as "tornado". A kind of disastrous weather. Under extremely unstable weather conditions, the strong convective movement of the air produces a violent rotating storm with a small diameter (the wind speed is above 27 meters per second). From the outside, it is a funnel-shaped cloud hovering from the bottom of the cumulonimbus cloud.

Dust storm: small cyclone, dust and other small objects produced by strong local heating of the ground in the near-surface gas layer are rolled up with the wind to form dust columns.

Ice needle: a weather phenomenon and one of the meteorological observation items on the ground. Flake or needle-like ice crystals formed by sublimation and growth of air vapor below -5℃. Shining in the sun can be distinguished, and sometimes other weather phenomena such as solar pillars or solar halos can be formed in the sky. It often appears in the severe winter season in high latitudes or plateau areas.

Snow: a weather phenomenon and one of the ground meteorological observation items. A layer of snow covering the earth's surface formed by snowfall.

Freezing: also known as freezing, is a weather phenomenon and one of the ground meteorological observation items. Open water freezes into ice. Meteorologically, water, including evaporating dishes, freezes.
