Where does the southeast wind blow From Where does the east wind blow from?

Blows from southeast to northwest.

Southeast Wind Interpretation:

The wind blowing from the southeast blows the wind from the northwest. Meteorologically, the direction in which the wind is blowing is determined as the direction of the wind. Therefore, the wind coming from the north is called the north wind. The wind coming from the south is called the south wind.

Causes: In summer, when the temperature rises in the southwest, the sea water will absorb a lot of heat from the air without obvious temperature changes, but it greatly hinders the rise of temperature, and due to the low temperature and high air density, it forms a high-pressure area on the ground. When the temperature rises in the northwest, the sand and gravel absorb a small amount of heat and the temperature rises quickly, so the temperature is high, the density is small, and the heat rises, forming a ground low pressure area.

Due to the difference in ground pressure between the two places, the air flows from southeast to northwest, which is the cause of southeast winds.

Wind direction in various places: In order to represent the frequency of wind occurrence in a certain direction, the quantity of wind direction frequency is usually used, which refers to the percentage of the number of times a certain direction of wind occurs and the total number of times of wind occurrence in each direction in a year (month), that is: wind direction change = the number of times a certain wind direction occurs The total number of observations of wind direction 100%, by the calculated wind direction frequency, you can know which wind direction is more and which wind direction is the least in a certain area.

According to the observations, northerly winds (northerly, northeasterly, and northwesterly) are mostly blowing in North China, the Yangtze River Basin, South China, and coastal areas of China, and southerly winds (southerly, southeasterly, and southwesterly) are blowing in summer.

The northwest wind is equal to the wind blowing from the southeast to the left, blowing in the northwest direction.

The tendency of the wind to blow is determined to be the direction of the wind. Therefore, the wind coming from due north is called cold wind (north wind), and the wind coming from the south is called smoke wind (south wind). When the wind is forecast at the Jingyu station, it is applied when the wind direction is uncertain when it fluctuates in a certain direction"Bias"words, such as the winter wind.

When the wind is very small, it is accepted"The wind is uncertain"to note.

An east wind refers to the wind that blows from east to west.

Meteorologically, the direction in which the wind is blowing is determined as the direction of the wind. Therefore, the wind coming from the east is called the east wind, the wind coming from the north is called the north wind, and the wind coming from the south is called the south wind. When the weather station forecasts the wind, when the wind direction swings left and right in a certain direction and cannot be determined, the word "bias" is added, such as northerly wind.

When the wind is very small, it is explained by "uncertain wind direction".

Wind Rating:

Generally, according to the various phenomena caused by the wind blowing on the ground or water surface, the wind force is divided into 13 levels, with the minimum being 0 and the maximum being 12. According to the national standard of "wind level" issued by China in June 2012, according to the wind speed at a height of 10 meters in the standard meteorological observation field, the wind level is divided into 18 levels, and there are three commonly used units to express wind speed, namely nautical mile hours, meter seconds, and kilometers per hour, and the commonly used units in typhoon forecasting in China are meter seconds.

In 2001, the China Meteorological Administration (CMA) issued the Regulations on Typhoon Operations and Services, supplementing typhoons above 12 to 17 on the Beaufort Wind Scale. Category 12 typhoons are set at meters and seconds; Level 13 is meter seconds; Level 14 is the meter second, level 15 is the meter second, level 16 is the meter second, and level 17 is the meter second.

In the typhoon in Qionghai 30 years ago, the maximum wind force near the center was 73 meters per second, which has exceeded the maximum standard of 17. It is called 18, which is also a common saying in the international maritime community about a mega typhoon.

The southeast wind is the wind that blows from the southeast to the northwest.

In meteorology, the direction of the wind is determined as the direction of the wind, the wind coming from the north is called the north wind, and the wind coming from the south is called the south wind. When the weather station forecasts the wind, when the wind direction swings left and right in a certain direction and cannot be determined, the Bi ethnic bias is added, such as northerly wind. When the wind is very small, the wind direction is uncertain.

The southeast wind is due to the difference in ground pressure between the two places, and the air will flow from the southeast to the northwest, forming a southeast wind.

There are 12 levels of wind speed.

The 12 levels of wind that are level 0 are called windless. The wind howls lightly, the leaves make a whisper, and the wind feels on people's faces. The fourth-level wind is called the Japanese wind, and the branches of the tree shake and can blow away the dust on the ground and the hand and the paper and the hand.

The sixth-level wind is called a strong wind, the branches are shaking, the wires are ringing, and you can't walk with an umbrella.

The eighth-level wind is called a strong wind, and the branches of the tree shed can be broken, and people are very resistant to walking against the wind. The wind of level 10 is called a squirrel, which is rare on land, can pull out trees, and does more damage to buildings. Winds above level 12 are called typhoons or hurricanes, which are very destructive and rare on land.

The south wind is the wind that blows from the south to the north. Meteorologically, the direction in which the wind is blowing is determined as the direction of the wind. Therefore, the wind coming from the north is called the north wind, and the wind coming from the south is called the south wind.

When the weather station forecasts the wind, when the wind direction swings left and right in a certain direction and cannot be determined, the word "bias" is added, such as northerly wind. When the wind is very small, it is explained by "uncertain wind direction". <>

Determination of wind direction.

One of the instruments for determining the wind direction is the wind vane, which is generally 10-12 meters high from the ground, if there is an obstacle nearby, its placement height should be at least 6 meters higher than the obstacle, and the short rod pointing north should be facing the north. The direction in which the wind arrow points indicates the direction of the wind at that time.

There is also a rectangular air pressure plate (800 grams for the heavy and 200 grams for the light one) next to the air pressure plate, which is equipped with a curved frame with long and short teeth. The number of long and short teeth raised by the air pressure plate indicates the strength of the wind. At present, meteorological stations generally use the EIJ type electric wind direction anemometer designed and manufactured by China.

The wind blowing from north to south is the north wind, and the wind direction refers to the direction in which the wind blows, which can be measured by the wind vane, and the direction indicated by the wind vane arrow is the wind direction; The Meteorological Observatory commonly publishes forecasts for wind direction in eight directions, namely East (E), South (S), West (W), North (N), Southeast (Se), Southwest (SW), Northwest (NW) and Northeast (NE).

The direct cause of the formation of the wind:

The ground is heated unevenly, causing the air to rise and sink in motion. This vertical movement of air creates a difference in air pressure in the same horizontal plane. As long as there is a pressure gradient in the horizontal plane, the force that causes the atmosphere to flow from the high pressure area to the low pressure area is generated, and this force becomes the horizontal pressure gradient force.

Under the action of this force, the atmosphere moves horizontally from the area of high pressure to the area of low pressure, so that the wind is formed.

Basic knowledge of science in elementary school (examples):

The gases needed for combustion are – oxygen;

The air on the surface of the earth is – from a place with a low temperature to a place with a high temperature;

The power that turns water into water vapor comes from the heat of the sun;

The way to get pure water is – distillation;

In summer, when you just come ashore from the water in the pool, you feel very cool, this is because when the water droplets on your body evaporate, you need to absorb the heat of the ** surface;

The method to remove sediment and insoluble impurities from water is - precipitation;

After the candle in the glass bell was extinguished, the water rose a little, indicating that the remaining air was - could not help burn.

When the wind blows south, it is the northern liquid that blocks the wind and withdraws the wind.

Meteorologically, the direction in which the wind is blowing is determined as the direction of the wind. Therefore, the wind coming from the north is called the north wind, and the wind coming from the south is called the south wind. When the weather station forecasts the wind, when the wind direction swings left and right in a certain direction and cannot be determined, the word "bias" is added, such as northerly wind.

When the wind is very small, it is explained by "the wind is uncertain".

The south wind blows from the south to the north.

The south wind is the wind blowing from the south to the north, and the wind direction refers to the direction in which the wind blows. The use of wind direction can play a positive role in people's life, production, factory construction, agriculture, transportation, military and other fields.

One of the instruments used to determine the direction of the wind is the weather vane

It is generally 10-12 meters above the ground, and if there is an obstacle nearby, its placement height should be at least 6 meters above the obstacle, and the short rod pointing north should be facing north. The direction of the wind arrow points to which direction it is indicative of the wind in which direction the morning brigade is being scraped at that time. There is also a rectangular air pressure plate on the air gauge (the heavy one weighs 800 grams, the light one weighs 200 grams), and next to the air pressure plate is a curved frame with long and short teeth on the frame.

The number of long and short teeth raised by the air pressure plate indicates the strength of the wind.

Ways to identify the direction of the wind:

The direction of the wind is the direction in which the wind is blowing. Specifically, the wind blowing from the north is the north wind, and the wind blowing from the south is the south wind. north wind (wind blowing from the north, the opposite of north is south, so the north wind blows south); The east wind (the wind blowing from the east, the opposite direction of the east is the west, so the east wind blows west) and so on, as long as you look at the direction of the arrow against the direction of the direction, it is the corresponding wind.

When we open our doors outdoors, we usually judge the direction of the wind based on the direction of the flag, the smoke and the branches of the trees. When the flag and the smoke drift to the south, it proves that the wind is blowing from the north, and the north wind is blowing at that time. When the flag and cooking smoke drift to the southeast, and the bright wind blows from the northwest, the northwest wind blows at that time.
