What are the advantages and disadvantages of weather phenomena we know?

1. Typhoon: tropical cyclone. When the wind force near the tropical cyclone center is ≥ 12, we call it a typhoon. Generally originated in tropical areas, from the Pacific Ocean called typhoon, from the Indian Ocean and the Atlantic Ocean called hurricane. Tropical cyclones that affect China generally originate from the Pacific Ocean, and most of them occur in July and August, which often bring violent storms.

Disadvantages: Strong wind overturns ships and houses, and heavy rain causes local mudslides, floods and other disasters.

Favorable: Precipitation can alleviate the summer drought in the Yangtze River basin in China and bring cool weather at the same time.

2. gale: a natural phenomenon caused by air flow, caused by solar radiation heat.

Disadvantages: it causes soil wind erosion and sand dune movement, and destroys farmland. Blindly reclaiming wasteland in arid areas, wind will lead to land desertification.

Advantages: Humans invented windmills to help production, and invented kites and sailboats. Later, wind power was used to generate electricity.

3, heavy snow: solid precipitation, mostly white opaque six-branched, hexagonal flaky crystals, often falling slowly, the intensity changes slowly. When the temperature is high, it often falls in droves.

Disadvantages: inconvenient transportation, cold climate, and cold climate will freeze the vegetation.

Advantages: crops and crops have been irrigated, and there is a folk proverb that there will be a good harvest when it snows.

Extended data:

1, precipitation phenomenon: according to the precipitation form * *11,there are three types of precipitation: liquid precipitation rain, Mao Mao rain, shower solid precipitation snow, ice particles, rice snow, snow shower, graupel, hail mixed precipitation sleet, intermittent precipitation, etc. According to the nature of precipitation.

2. Surface condensation and freezing phenomena: including dew, frost, fog and rain.

3. Sight distance obstacle phenomenon: including fog (fog, fog, dense fog); Light fog; Blow snow; Blizzard; Smoke screen; Haze; Sandstorm (sandstorm, strong sandstorm, super sandstorm); Blowing sand; Floating dust.

4. Lightning phenomenon: thunderstorm, lightning and aurora.

5. Its phenomena: wind, squall, tornado, sandstorm, ice needle, ice and snow.
