High winds, high winds, gale winds, gusty winds, storms and hurricanes, these common types of wind, the Buffalo winds are seven, eight, nine, ten, eleven and twelve.
Gust: When the flow speed of the air is large and small, it will make the wind suddenly become larger and smaller, and there will be a burst of feeling on the body. This is the gust of wind recognized in life. In meteorology, the wind speed usually refers to the average condition within 2 minutes, while the wind speed is large and small, and the gust usually refers to the maximum instantaneous wind speed during this time. If the weather forecast, today's wind is 4-5, gust 6, that is to say, the average wind today is 4-5, and the maximum instantaneous wind can reach 6.
Cyclone: When air carries dust in the air to form a vortex, this is a whirlwind.
Foehn wind: When the air crosses the ridge, because the air sinks, a warm (or hot) and dry wind is easy to occur on the leeward slope, which is called Foehn wind.
A typhoon is an atmospheric vortex that occurs in a tropical ocean, so it is also called a tropical cyclone. When the maximum wind force of the vortex center reaches level 8 or above, it is called typhoon; the center maximum wind force is called weak typhoon in level 6 to 7; when the center maximum wind force reaches level 8 to 12, it is called strong typhoon.
Tornado: A vortex of air that extends from the cumulonimbus cloud to the ground with a small range and great destructive power. What happens on land is called Lu Longjuan, what happens on the ocean is called Sea Tornado, and it is also called Water Tornado. A tornado is a violent storm with strong rotation, and the wind speed can reach more than 100 meters per second.
Valley wind: In mountain areas, the wind blows up the hillside and valley during the day, and down the hillside and valley at night. This kind of wind that changes the direction of the wind between the hillside and the valley with the day and night is called the valley wind.
Sea and land breezes: In the near-shore area, the wind blows from the sea to the mainland during the day, and from the land to the sea at night. This kind of wind that alternates day and night and changes direction regularly is called land and sea breeze.
Glacier wind: During the day and night, the shallow wind blowing along the glacier downhill.
Monsoon: As the seasons change, the prevailing wind direction changes regularly. In winter, air flows from high-pressure land to low-pressure sea, which is called winter monsoon; in summer, wind blows from sea to land, called summer monsoon. China is a country with a significant monsoon. It tends to be northerly in winter and southerly in summer. This brings the characteristics of monsoon climate with dry winter and wet summer to most parts of China.
Trade winds: In the lower atmosphere, from the subtropical high to the sustained winds in the equatorial region. In the northern hemisphere, the prevailing trade wind is northeast; in the southern hemisphere, it is southeast. Trade winds are characterized by a high degree of recurrence, blowing in one direction with almost constant power throughout the year.
Anti-trade winds: The hot air that rises at the equator reaches the upper atmosphere and flows in two stages. This kind of airflow is called anti-trade winds. Due to the rotation of the earth, anti-trade winds are to the right in the northern hemisphere and to the left in the southern hemisphere. Anti-trade winds constantly bring the atmosphere to the latitude between 30 ° and 35 °, forming a state of air accumulation, forming a subtropical high belt. Therefore, there are many deserts in this area. |
