What kind of wind hangs in winter, and how to calculate the wind direction? The wind is always there

Different latitude and longitude in different places are not the same wind direction, I am from Ningbo, Zhejiang, winter is generally dominated by the northwest wind, the wind direction refers to the direction of the wind blowing, such as taking a red scarf, the red scarf to the southeast direction means that the wind is blowing in the northwest direction, it is called the northwest wind. Hope it helps!

A northerly wind that generally blows in winter.

In winter, there should be more in the northwest, and the wind direction is calculated from the direction from which it blows, and it is what kind of wind it blows from.

In most parts of China, the wind direction changes regularly throughout the year, which is determined by the geographical location of China, mainly the configuration of sea and land. Due to the difference in the thermal characteristics of the continent and the ocean, a cold high pressure is formed in the interior of Asia in the severe winter, and a hot low pressure is relatively formed on the ocean in the east and south, and the air in the high pressure area will flow to the low pressure area, which will form the northerly and northwesterly winds in China's winter.

Most of our country is in the monsoon zone, so the winter is basically northwesterly.

The wind is looking in the right direction.

This is not necessarily, it depends on your geographical location, different regions have different climates, and the wind direction will be different. Wind direction refers to the direction in which the wind is blowing.

Which place are you asking, if it's Beijing, of course, it's blowing from the northwest, so it's called the northwest wind...

In winter, the northwesterly winds blow from the cold Siberian current

The northeast or northwest wind is a cold snap from the north.

Think for yourself in the winter.

There are many north winds blowing in winter, and whichever direction the wind comes from, it is even what kind of wind it is!

The north wind is what it blows from.

The direction in which the wind blows out is the downwind direction.

Prevailing winds, also known as the most wind directions, refer to the winds or wind directions that occur most frequently in a certain period of time in an area. It is usually calculated by day, month, quarter and year to find the prevailing wind direction in the corresponding period.

Prevailing wind downwind direction: It is the downwind outlet with the most wind direction and dominant wind direction in the region, the wind direction and downwind direction of wind movement.

Prevailing wind: also known as the most wind direction and dominant wind direction, refers to the wind or wind direction with the highest frequency in a certain period of time in a region. For example, if the northwest wind blows the most in the area of the year, that is, the northwest wind frequency is the largest, then the perennial dominant wind direction is the northwest wind, and the prevailing wind in this area is the northwest wind.

Downwind: Refers to the direction below the direction of the wind, that is, the direction of movement of the wind is the downwind direction.

The factory is built in the direction of the prevailing wind, which can make the factory exhaust blow in the opposite direction of the residential area, and its purpose is to reduce the pollution of the ambient air in the residential area by the exhaust gas emitted by the factory.

The location of Industrial Zone C is the downwind direction of the prevailing winds.

Books often say that the industrial zone should be arranged in the suburbs perpendicular to the direction of Shengxing, which refers to the location of the two industrial zones A and B.

In a word, this arrangement is to prevent the wind from blowing pollutants into the urban area and polluting the environment.

The downwind direction of the prevailing wind.

Prevailing winds are the prevailing wind directions in the region and refer to the wind direction that occurs the most in the region during a certain period of time. The prevailing winds are for the time period studied, such as the prevailing winds in a certain month, the prevailing winds in a certain season, and the prevailing winds throughout the year. It is not specific to say only the prevailing winds, not the time period, and can only refer to all prevailing winds.

If the wind blows from A to B, then B is downwind and A is upwind. The wind direction is also specific to the wind studied, such as the downwind direction of the prevailing wind in a certain place throughout the year, and the downwind direction of the wind in a certain place at x o'clock on the xth day of the xth month. If you only talk about the downwind direction, not what kind of wind or which wind it is, you can't correspond to the downwind direction and the geographical direction, but only the downwind direction.

Factories emit harmful gases or dust into the air. It is precisely in order to reduce the impact of hazardous substances on people that it is necessary to build factories downwind. If the factory is upwind and the residential area is downwind, the gases and dust emitted by the factory will be carried by the wind to the downwind residential area.

But it is almost impossible to blow only one wind direction in any one place forever, so no matter whether the factory is built in **, it is impossible to guarantee that it will always be in the downwind direction. Built in the downwind direction where the prevailing wind prevails, you can try to ensure that the factory is in the downwind direction more often.

As for pollution, it will pollute as long as harmful substances are emitted. And just because the factory is built downwind, the emissions don't pollute the environment. It's just that the factory is built downwind to reduce the harm to people nearby.

As harmful gases and dust drift farther and farther, they will gradually diffuse and dilute, and the impact on people will be weakened when the concentration is reduced. However, the degree of pollution has not changed, and the degree of pollution is only related to the substances emitted and the amount of emissions.

Suppose there are two places A and B If the wind blows from A to B, then A is upwind and B is downwind. The prevailing wind refers to the perennial blowing of this wind in this place. The factory is to be built in the downwind direction of the prevailing wind, so that the pollution caused will be relatively small, and it cannot be said that it will not pollute the environment, this is just like the water plant should be built in the upstream of the river, and the power plant and cement plant should be built in the downstream of the river.

Hehe, in short, draw a long arrow to represent the direction of the wind, write a word on the arrow, and write a word on the back and you will understand, so the polluted factory should be laid out to the downwind direction of the prevailing wind! Good luck and I hope you get the idea!

The downwind direction of the prevailing wind refers to the place where the wind leaves. It will not pollute the environment.

For example, if a westerly wind prevails, the east side is downwind.

If the factory is built downwind, it will not pollute the city's environment.

The opposite direction of a wind direction is the downward direction of it.

In this way, the pollution of the living environment of residents living downwind of the factory can be avoided.

The prevailing wind is the wind that blows frequently, and the downwind direction is the direction in which the wind will blow, and the best explanation is when they are connected together.

The prevailing wind is the direction from which the wind mainly blows.

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".

For example, if it's an east wind, it's wind blowing from the east.

Wind direction, in general, there are different methods when determining it. It is mainly divided into oceans, continents, and high altitudes. The use of wind direction can play an active role in people's life, production, factory construction, agriculture, transportation, military and other fields.

Extended Materials. Wind is a natural phenomenon caused by the movement of air, and it is caused by the heat of solar radiation. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the air on the surface of the earth is heated and expands lightly and rises.

When the hot air rises, the cold air at a low temperature flows in laterally, and the rising air cools and becomes heavier and falls, and the air heats up to rise due to the high surface temperature, and the flow of this air generates wind.

From a scientific point of view, wind often refers to the horizontal movement component of air, including direction and magnitude, i.e., wind direction and speed; But for flight, it also includes the vertical motion component, the so-called vertical or ascending airflow. Gale moves objects in relation to the direction of the object (mass of matter). The speed of the wind is fast.

The direction of the wind refers to the direction in which the wind blows, and the east is the wind blowing from the east.

The east wind is the wind that blows from the east, called the east wind.

The wind blowing from the east is called the east wind.

Customs, from where the wind blows.

It is called a wind from any direction, for example, the east wind blows from the east.

People often say that the east wind is not the wind blowing from the east.

It is the wind that blows to the east that is called the east wind.

1. Winter monsoon:

Origin: Mongolian-Siberian high (also known as Asian high).

Wind direction: northerly.

Characteristics: cold and dry, control most of our country, control our country for a long time.

Disasters: high winds, cooling, sandstorms, blizzards, etc.

2. Summer monsoon:

Origin: Mainly the subtropical high over the northwest Pacific Ocean, but also from the Indian Ocean.

Wind direction: Southerly.

Characteristics: warm and humid, control the eastern part of our country, the control range is smaller than the winter monsoon, and the control time of our country is shorter.

Disasters: Abnormal summer monsoon activity will bring floods and droughts; Larger flood disasters can also cause geological disasters.

In China, the winter monsoon is northwesterly, the source is Siberia, and the nature is cold and dry; The summer monsoon is the southeast wind, the source is the Pacific Ocean, the nature is warm and humid, the winter monsoon is stronger than the summer monsoon, so our country is divided into monsoon and non-monsoon areas, the winter monsoon is strong, throughout the country.

In the summer of East Asia, the continent formed an Asian low pressure, blowing southeast winds from the ocean, bringing large water vapor. In India, the southwest monsoon (the southeast trade winds in the southern hemisphere are formed by geostrophic deflection forces across the equator) and the northwesterly winds blow from East Asia in winter, coming from the Mongolian-Siberian high pressure, which is colder and drier. In India, there is a northeasterly wind.

The situation is different in different places Our East Asian countries are mainly affected by the Siberian high pressure area of Russia in winter, so it is basically a northwest wind or a north wind Every winter, the cold currents are also brought over there, and the summer is affected by the tropical high pressure in the Pacific Ocean, so the southeast wind is basically blown Typhoon is a typical example As for the South Asian subcontinent, due to its unique geographical factors, the north is blocked by the Himalayas, so the climate is still somewhat different from our country All the winds and rain bands in summer are mainly from the Indian Ocean... I forgot the rest, but I learned this in high school geography n years ago... o⊙ )

Siberia, cold and dry, Pacific, warm and humid.

This question is relatively simple, I know, I will send you the detailed answer as soon as possible, please be patient and wait, I will help you solve your problem immediately.

1. Judge the wind direction

The direction of the wind represented on the Rose Chart is the direction in which the wind is coming from, and it is the direction in which it blows from the outside to the center of the area.

2. Judge the wind direction and frequency

Wind direction frequency is the number of occurrences of various wind directions in a given time as a percentage of all observations. The longer the line segment in the Wind Rose diagram, that is, the greater the distance from the outside to the center, the greater the wind frequency, which is the local dominant wind direction; Outside to the center.

The smaller the distance, the smaller the wind frequency, which is the minimum wind frequency in the local area.

In the case of the Wind Direction Rose Chart, the wind direction is blowing from the periphery to the center, and the length away from the center indicates the frequency of that wind direction, and the farther away from the center is the higher frequency of the wind direction. The green dotted line indicates summer, and the solid yellow line indicates winter.

Taking Shanghai as an example, southeasterly and southeasterly winds are the most common in summer, and southeast winds are more frequent in winter, and the frequency of easterly and northwesterly winds is about the same.

The wind direction is blowing from the periphery to the center, and the length away from the center indicates how often that wind direction occurs, and the farther away from the center is the more frequent the wind direction occurs. The green dotted line indicates summer, and the solid yellow line indicates winter.

How to see the picture:

1. Judge the direction of origin:

The direction of the wind is the direction in which it blows from the outside towards the center of the area. The green line represents summer and the yellow line represents winter.

2. Judge the size:

The distance of the point on the polyline from the center of the circle indicates the frequency of the wind blowing from this point towards the center of the circle. The solid line indicates the perennial monsoon and the dotted line indicates the summer monsoon.

3. Judgment frequency:

The closed pattern formed by the solid line and the focus of the 4 coordinate lines represent the magnitude of the wind, and the farther away from the center, the greater the frequency of this wind direction.

Wind direction refers to the direction in which the wind is blowing. 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".

However, in meteorology, it is generally divided into 12 levels according to the magnitude of the wind: level 0 wind is also called no wind. Category 2 winds are called light winds.

Level 4 wind is called Japanese wind. A force 6 wind is called a strong wind. A level 8 wind is called a gale.

A force 10 wind is called a squirrel. Winds above 12 are called typhoons or hurricanes.

The wind direction is represented by the weather vane, which is composed of wind poles and wind tails or wind flags. The bar on the wind pole is called the wind tail, and the side with the wind tail drawn on the wind pole indicates the wind direction. Generally, according to the various phenomena caused by the wind blowing on the ground or water surface, the magnitude of the wind force is divided into 18 levels, the minimum is 0, and the maximum is 17.

In which direction the wind blows, look at these weather vanes to make it clear.

Wind direction refers to the direction in which the wind blows.

Wind direction refers to the direction in which the wind is blowing.

Meteorologically, the direction in which the wind is blowing is determined as the direction of the wind. Therefore, when the wind comes from the north, it is called the north wind, and when the wind comes from the south, it is called the south wind.

If it is an east wind, it is the direction of the wind coming from the east, and so on, that is, the wind direction refers to the wind coming from which direction, which is called the X wind.

The wind blows from whichever direction it blows.

The direction of the wind should be the direction in which the wind is blowing.

1 4 Step by Step Reading.

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.

2 4 When we are outdoors, we generally judge the direction of the wind based on the direction of the flag, the smoke and the branches of the trees.

3 4 When the flag and the smoke of the cooking are blowing to the south, it is a sign that the wind is blowing from the north, and the wind is blowing from the north.

4 4When the flag and the smoke of the cooking are blowing in the southeast direction, it proves that the wind is blowing from the northwest, and the northwest wind is blowing at that time.
