How does geography judge what wind is blowing? 1, judged by monsoon climate characteristics. China mainly blows northerly winds in winter; The south wind blows mainly in summer. In winter in South Asia, the northeast wind blows; In summer, the southwest wind blows.
2. From the temperate maritime climate and Mediterranean climate. According to the climate characteristics, the temperate maritime climate blows west wind all the year round, southwest wind blows in the northern hemisphere and northwest wind blows in the southern hemisphere. The climate of the Mediterranean is westerly in winter.
3. Use the distribution map of sea level isobar to judge. For example, in the distribution map of sea level isobar in the northern hemisphere, A is the center of high pressure and B is the center of low pressure, so ① northwest wind prevails and ② southwest wind prevails.
4. Judging by the characteristics of monsoon climate. China mainly blows northerly winds in winter; The south wind blows mainly in summer. In winter in South Asia, the northeast wind blows; In summer, the southwest wind blows.
5. Judging by temperate maritime climate and Mediterranean climate. According to the climate characteristics, the temperate maritime climate blows west wind all the year round, southwest wind blows in the northern hemisphere and northwest wind blows in the southern hemisphere. The climate of the Mediterranean is westerly in winter.
6, using cyclone and anticyclone diagram to judge.
When judging the wind direction, pay attention to where the cyclone is. Generally, the south wind blows below the cyclone and the north wind blows above it; The west wind blows on the left side of the cyclone and the east wind blows on the right side of the cyclone.
What are the winds in geography and nature? 1. Gust: When the air speed fluctuates up and down, the wind will fluctuate greatly, and people will feel it for a while. This is a recognized gust of life. Meteorology, wind speed usually refers to the average situation within 2 minutes, with high or low wind speed, and gust usually refers to the maximum instantaneous wind speed during this period. If the weather forecast, today's wind is 4-5, and the gust is 6, which means that today's average wind is 4-5, and the maximum instantaneous wind can reach 6.
2. Cyclone: When the air flies in the air with dust to form a vortex, this is a whirlwind.
3. Foehn: When the air crosses the ridge, it is easy to produce warm (or hot) dry wind on the leeward slope due to the sinking of the air, which is called Foehn.
4. Typhoon: It is an atmospheric vortex that occurs in the tropical ocean, so it is also called a tropical cyclone. When the maximum wind force in the vortex center reaches more than 8, it is called typhoon; The maximum wind force in the center is 6-7, which is called weak typhoon; When the maximum wind force in the center reaches 8 to 12, it is called a strong typhoon.
5. Tornado: A small destructive air vortex extending from the cumulonimbus cloud to the ground. What happens on land is called tornado, and what happens on the ocean is called tornado, also called waterspout. Tornado is a violent storm with strong rotating force, and the maximum wind speed can reach more than 100 meters per second.
6. Mountain and valley wind: In mountainous areas, the wind blows up along the slopes and valleys during the day and down along the slopes and valleys at night. This wind, which changes direction between hills and valleys alternately day and night, is called valley wind.
7. Sea-land wind: In coastal areas, 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 changes direction regularly day and night is called land-sea wind.
8. Glacier wind: shallow wind blowing down the mountain along the glacier during the day and night.
9. Monsoon: With the alternation of seasons, the prevailing wind direction changes regularly. In winter, air flows from high-pressure land to low-pressure sea, which is called winter wind; In summer, the wind blows from the sea to the land, which is called summer monsoon. China is a country with remarkable monsoon, with northerly winds in winter and southerly winds in summer. This brings the monsoon climate characteristics of dry winter and wet summer to most parts of China.
10. Trade winds: persistent winds blowing from subtropical high to equatorial regions in the lower atmosphere. In the northern hemisphere, trade winds prevail in the northeast; In the southern hemisphere, it is in the southeast. Trade winds are characterized by a high degree of regularity, blowing in one direction with almost constant intensity all year round.
