The definition of weather, what is the meaning of weather

Weather refers to the atmospheric conditions of a particular region over a short period of time. The weather is constantly changing, for example, the temperature may be high or low, the air will be cold and warm, the wind will be strong and small, and the water in the air will exist in various forms such as dense fog, mist, raindrops, hail, snowflakes, freezing rain, etc. All of these meteorological factors are manifestations of the weather.

The weather is unpredictable and unpredictable.

Tornadoes can sweep in with winds of 113 km/h. It has an average wind speed of 16 km/h and 32km/h. Tornadoes do not travel very long distances on the ground, and tornadoes that travel more than 10 kilometers are rare.

You're not the only one who needs to take shelter from the rain in a storm. Where do the animals go when the weather is bad? To escape extreme temperatures, many animals burrow underground.

In summer, the soil cools the animal's body; In winter, the soil protects them from the cold, snow and ice. And when it comes to sheltering from the rain, animals need shelter just as much as you do. They don't bring umbrellas, so you'll have to find a sheltered place to wait for the rain to stop!

The method should start from the source, practice more, and then put the mentality in place.

Weather refers to the specific state of the atmosphere in a certain area close to the earth's surface in a short period of time. Weather phenomena refer to various natural phenomena that occur in the atmosphere, that is, the comprehensive performance of the spatial distribution of various meteorological elements (such as temperature, air pressure, humidity, wind, clouds, fog, rain, flash, snow, frost, thunder, hail, haze, etc.) in the atmosphere in a certain instant.

Weather processes are the process of changing weather phenomena in a certain area over time. All kinds of weather systems have certain spatial and temporal scales, and the various scale systems are intertwined and interact with each other. The combination of many weather systems constitutes a large-scale weather situation that constitutes the atmospheric circulation of the hemisphere or even the world.

Weather systems are always in the process of rebirth, development and disappearance, and have their corresponding distribution of weather phenomena at different stages of development.

Causes of wind. The direct cause of the formation of wind: the uneven distribution of air pressure in the horizontal direction.

Wind is affected by different factors such as atmospheric circulation, topography, and water, and has a variety of manifestations, such as monsoon, local sea and land breeze, valley wind, foehn wind, etc. To put it simply, wind is the directional motion of air molecules. To understand the causes of wind, we must first clarify two key concepts:

air and air pressure. The composition of air includes: nitrogen molecules (78% of the total volume of air), oxygen molecules (about 21%), water vapor and other trace components.

All the air molecules were moving at a rapid pace, colliding with each other and with anything on the horizon. Wind. Atmospheric pressure.

It can be defined as: the amount of pressure exerted by air molecules in a given region. Generally speaking, the more air molecules are present in a certain area, the greater the air pressure in that area.

Correspondingly, wind is the result of the action of a pressure gradient force. Some changes in air pressure are caused by storms, some are caused by uneven surface heating, and some are caused by atmospheric molecules being forced to flow from a relatively high pressure zone to a low pressure zone in a certain horizontal area. Most of the high-pressure and low-pressure bands shown on the weather map just form a mild breeze that accompanies us.

The difference in air pressure required to produce a breeze is only 1% of the atmospheric pressure itself, and this change in air pressure occurs over many areas. Comparatively speaking, the formation of severe storms results from changes in larger, more concentrated areas of pressure.

The effects of wind. Wind is one of the environmental factors in agricultural production. Moderate wind speed plays an important role in improving the environmental conditions of farmland.

The heat exchange near the surface, evapotranspiration of farmland and the transport of carbon dioxide and oxygen in the air are accelerated or strengthened with the increase of wind speed. Wind spreads plant pollen, seeds, and helps plants pollinate and reproduce. Wind energy is a widely distributed and inexhaustible source of energy.

The monsoon prevails in China, which is beneficial for crop growth. In the Inner Mongolia Plateau, the Northeast Plain, the southeast coast and the inland high mountains, there are abundant wind energy resources available.

The easiest way to describe the weather is that some regions have different weather conditions with various colors. Different weather in different places. So sunshine, rain, shade and sunshine are all possible.

Weather is a kind of foreshadowing of how the human body perceives the change in temperature, prompting people to dress, exercise, work, plant, etc.

The atmospheric conditions of a region at a given time as determined by various meteorological elements.

God is angry, and if you want to change your face, you can change it, so there are spring, summer, autumn and winter, cold, warm, rain and snow.

Good loneliness is a big reminder to any you have encountered also lyrics.

Literal understanding of the outside weather, atmospheric conditions?

Definition 1: The state of the atmosphere in a region at a given time as determined by various meteorological elements.

Definition 2: Atmospheric conditions as determined by various meteorological elements at a given moment or over a period of time.

Weather refers to short-term changes in the atmosphere, such as weekly weather conditions.

Climate refers to the average change in the atmosphere over a long period of time, such as the rainy season in spring and summer.

To put it simply, it is the atmospheric condition composed of various meteorological elements in a certain moment or period of time in a region.

It mainly includes, solar light (and the influence of clouds and fog on solar illumination), temperature, precipitation, wind speed, and air humidity. In addition, air pressure is also an important part of weather conditions.
