What weather phenomena do I know about?

Wind, rain, snow, ice, etc.

Rain: drop-shaped liquid precipitation, which is clearly visible when falling and changes in intensity slowly. When it falls on the water, it will stir up ripples and splashes, and when it falls on the ground, it will leave wet spots. Showery rain: Liquid precipitation that starts and stops suddenly and changes in intensity greatly, sometimes accompanied by thunderstorms.

Drizzie: Dense, fine and very uniform liquid precipitation. The falling situation is difficult to distinguish. It seems to be floating in the air with the weak movement of the air, falling slowly, with a feeling of moisture on the face, and falling on the water surface. There are no ripples on the surface, it only moistens evenly when it falls on dry ground, and there are no wet spots on the ground.

Snow (snow): Solid precipitation, mostly white opaque six-branched star-shaped and hexagonal flake crystals, often falling slowly and changing intensity slowly. When the temperature is relatively high, they tend to fall in groups.

Snow shower (showery): Solid precipitation phenomenon in weather phenomena. Snowfall that lasts for a short period of time, starts and ends suddenly, and changes in intensity greatly.

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

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

Graupel: Solid precipitation phenomenon in weather phenomena. It is composed of white opaque spherical or conical particles with a diameter of about 2 to 5 mm. They often fall in bursts and often rebound when they fall on hard ground. They are brittle and brittle.

Snow grains: Solid precipitation phenomenon in weather phenomena. It is composed of white opaque oblong ice particles with a diameter of less than 1 mm. It does not bounce when it falls on the hard ground.

Ice pellet: also known as ice pill. Solid precipitation phenomena in weather phenomena. It consists of transparent pellet-shaped or irregular particles with a diameter less than 5 mm. It is relatively hard and bounces when it falls on hard ground. Sometimes there is unfrozen water inside. If it is smashed, only the broken ice shell will remain.

Hail: Hard spherical, cone-shaped or irregular-shaped solid precipitation. The inner core is generally opaque and is covered with a transparent ice layer, or is composed of transparent ice layers and opaque ice layers. The size varies greatly, and the diameter of the largest ones can reach tens of millimeters. Often accompanied by thunderstorms.

Dew: A type of ground condensation phenomenon. When the temperature is above freezing, water vapor condenses on the ground and ground objects to form water droplets. Easy to form at night.

Frost: A type of ground condensation phenomenon. When the temperature is below freezing point, water vapor condenses on the ground and ground objects to form white, crisp ice crystals, or ice beads formed from dew freezing. It is easy to form at night when the wind is clear and the wind is light.

Rime: One of the condensation phenomena on the ground. The water vapor in the air directly condenses, or the supercooled mist droplets directly freeze on the object. Often hairy needle-like, or granular with uneven surface. The structure is relatively fragile and prone to collapse when exposed to earthquakes.

glaze: one of the ground condensation phenomena. A hard layer of ice formed when supercooled raindrops directly freeze when they hit a ground object with a lower temperature (0~-3°C). It is transparent or frosted glass, with a smooth or slightly ridged appearance. Mainly generated on the windward side.

Fog: A type of visual range obstruction phenomenon. When there is sufficient moisture, breeze, and a stable atmosphere, when the air close to the ground cools, the moisture in the air condenses into tiny water droplets suspended in the air, reducing the horizontal visibility at the ground to less than 1.0 kilometers. It is divided into three levels: 0.5 kilometers ≤ visibility < 1.0 kilometers is fog; 0.05 kilometers ≤ visibility < 0.5 kilometers is dense fog; visibility < 0.5 kilometers is strong dense fog.

Mist: formerly known as "mist". A type of visual impairment. The thin gray-white fog curtain composed of tiny water droplets or hygroscopic particles makes the horizontal visibility range from 1 to 10 kilometers.

Driven snow: a type of visual impairment. Strong winds blow up snow flakes (snowflakes, snow particles) on the ground, reducing horizontal visibility to less than 10.0 kilometers.

Snowstorm: Commonly known as "blizzard". A type of visual impairment. A large amount of snow was picked up by strong winds and moved with the wind, making the horizontal visibility less than 1.0 kilometers, and it was impossible to determine whether there was snowfall in the sky at that time. When it occurs, the wind is freezing and the roads are buried, often causing disasters.

Smoke screen: A type of visual impairment. A weather phenomenon in which the air contains a large amount of smoke, reducing horizontal visibility to less than 10.0 kilometers. The air above cities, industrial and mining areas is black, gray or brown, and when it is thick, you can smell smoke.

Haze: A type of visual impairment. A large number of very fine dry dust particles are evenly suspended in the air, the air is turbid, and the horizontal visibility is less than 10.0 kilometers. Make bright objects in the distance slightly yellow or red, and dark objects slightly blue. When visibility is less than 3 km, it becomes a type of disastrous weather.

Sand and dust storm, sand-dust storm, dust storm: also known as "sandstorm, dust storm". A type of dust weather. Strong winds stirred up sand and dust on the ground, making the air turbid and reducing horizontal visibility to less than 1,000 meters.

Blowing sand: a type of sand and dust weather. The wind blows up the sand and dust on the ground, making the horizontal visibility between 1 and 10 kilometers.

Suspended dust: a type of sandy weather. It usually occurs after blowing sand or a sandstorm. Under weather conditions with no wind or average wind speed ≤ 3 m/s, a large amount of sand and dust floats in the air, making the horizontal visibility less than 10 kilometers.

Thunderstorm: ① A local storm accompanied by lightning, thunder and heavy bursts of precipitation caused by cumulonimbus clouds with strong convection. ② In ground observation, it only refers to weather phenomena accompanied by thunder and lightning. Sometimes only thunder is heard but lightning is not seen.

Lightning: A strong discharge in the atmosphere accompanied by luminescence. According to the location where it occurs in the sky, it can be divided into three categories: in the cloud, between the clouds and between the clouds and the ground. According to the different shapes of lightning channels, they can be called linear, ribbon, sheet, spherical, fork-shaped, rocket-shaped, beaded lightning, etc.

Aurora: When charged particles (solar wind) from the sun enter the earth's magnetic field and pass through the upper atmosphere near the earth's north and south poles, they collide and excite atmospheric atoms, forming a brilliant brilliance high in the sky. Those that appear in the Antarctic are called the Aurora Australis, and those that appear in the North Pole are called the Northern Lights.

Gale: a type of disastrous weather. Caused by strong weather processes such as cold fronts and tropical storms, near-surface winds reach level 8 (average wind speed 17.2~20.7 meters/second) or above.

Squall: refers to a narrow band of strong winds that appears in front of a strong cold front or a cumulonimbus cloud. When passing through, the wind speed increases suddenly, the wind direction changes suddenly, meteorological elements change rapidly, and it is often accompanied by bursts of precipitation.

Tornado: also known as "tornado". A type of disastrous weather. Under extremely unstable weather conditions, a small-diameter violent rotating storm (wind speed above 27 meters/second) is generated by strong convective movement of air. From the outside, it looks like a funnel-shaped cloud body hanging down from the base of the cumulonimbus cloud.

Dust devil: A small whirlwind generated in the air layer near the ground due to strong local heating of the ground. Dust and other small objects are rolled up by the wind to form a dust column.

Ice needle: a type of weather phenomenon and one of the ground meteorological observation items. Thin flakes or needle-shaped ice crystals formed by the growth of water vapor in the air at temperatures below -5°C. They can be seen twinkling under sunlight, and sometimes other weather phenomena such as sun pillars or halos can form in the sky. It often occurs in severe winter seasons in high latitudes or plateau areas.

Snow cover: a weather phenomenon, one of the ground meteorological observation projects. A layer of snow formed by snowfall that covers the Earth's surface.

Freezing: Also known as freezing, it is a kind of weather phenomenon and one of the ground meteorological observation items. Refers to open water freezing into ice. Meteorologically, water in an evaporating dish freezes into ice.
