How many snowflakes are represented by "moderate snow" in the weather forecast?

"Moderate snow" in the weather forecast is represented by two snowflakes.

Sunny: It means that the sky is cloudless or there are scattered clouds, but the amount of clouds accounts for less than 1/10 of the sky. It is called clear. Sometimes there are very high and thin clouds in the sky, but they are not affected by the sunlight. Those with little influence are also called clear.

Cloudy: When the amount of medium and low clouds in the sky accounts for 4/10 to 7/10 of the sky area, or when the amount of high-altitude clouds accounts for 6/10 or more of the sky area, it is said to be cloudy.

Overcast: When the amount of medium and low clouds accounts for 8/10 or more of the sky area, it is called overcast. A cloudy day is when the sky is dark and little or no sunlight penetrates the clouds.

Light rain or moderate rain: The rainfall in 24 hours is less than 10.0 mm or the rainfall in 1 hour is less than 2.5 mm. It is called light rain. The rainfall in 24 hours is 10.0~24.9 mm or the rainfall in 1 hour is between It becomes moderate rain when it is between 2.5 and 8.0 mm.

Heavy rain: It is called heavy rain when the rainfall in 24 hours is less than 25.0~49.9 mm or when the rainfall in 1 hour reaches 8.1~15.9 mm.

Heavy rain: When the rainfall reaches or exceeds 50.0 mm within 24 hours and the rainfall reaches or exceeds 16.0 mm within 1 hour, it is called a heavy rain. A rainfall reaching 100.0 to 199.9 mm is called a heavy rainstorm; a rainfall reaching 200.0 mm is called a heavy rainstorm;

Hail: It is a kind of solid precipitation. Refers to the spherical or conical ice cubes with a diameter of 5.0 mm that will rain heavily in the clouds. The shape may also be irregular. The individual units are called hailstones, which are composed of transparent and opaque layers. The diameter of large hailstones can be up to 19 centimeter.

Thunderstorm: refers to burst rainfall accompanied by thunder and lightning. It is characterized by short rainfall, sudden start and end, and large changes in rainfall intensity.

Sleet: refers to the precipitation phenomenon in which raindrops and wet snow fall to the ground at the same time. When it occurs, the temperature near the ground is slightly above 0°C. When snow falls into this layer of air, part of the snow melts into water droplets.

Light snow: refers to snowfall when the horizontal visibility exceeds 1,000 meters or the snowfall amount within 24 hours is less than 2.5 mm.

Medium snow: refers to snowfall when the horizontal visibility exceeds 500 to 1,000 meters or the snowfall amount within 24 hours is less than 2.5 to 5.0 mm.

Heavy snow: refers to snowfall when horizontal visibility is less than 500 meters or when snowfall exceeds 5.0 mm within 24 hours.

Fog: refers to a large number of water droplets or ice crystal particles suspended in the air near 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.

Frost: During the transition between spring and autumn During the season, the daytime temperature is higher than 0℃, and the nighttime temperature drops below 0℃ for a short period of time. When it occurs, the temperature inside the shutter box may not be lower than 0℃; hoarfrost often appears on the ground or on the surface of objects.

Category 6 wind: refers to the wind speed of 10.8 to 13.8 meters/second at a height of 10 meters above the ground.

Level 7 wind: refers to the wind speed of 13.9 to 17.1 meters/second at a height of 10 meters above the ground.

Wind level 8 to 12: refers to the wind speed at a height of 10 meters above the ground reaching 17.2 to 20.7 meters/second, 20.8 to 24.4 meters/second, 24.5 to 28.4 meters/second, and 28.5 to 32.6 meters respectively. / second, 32.7~35.9 meters/second, respectively, are called level 8 wind, level 9 wind, level 10 wind, level 11 wind and level 12 wind.

Typhoon: refers to a strong warm-core cyclonic vortex that occurs in the tropical ocean. When the average wind strength near the center reaches level 12 or above, it is called a typhoon.
