What role does water play in regulating the climate?

It's a bit of a physical component, the summer temperature is higher, and the water molecules.

The movement intensifies, the vaporization accelerates, and the heat is absorbed. Because of the specific heat capacity of water.

large, the temperature rises or decreases by one degree Celsius.

There is more heat that needs to be absorbed or released, so the temperature can be controlled from being too extreme. The temperature difference between day and night in coastal areas is small, while the temperature difference between day and night in inland areas is large, which is caused by the specific heat capacity of sand and gravel being smaller than that of water. It can be seen that water plays an important role in regulating air temperature.

The climate is determined by the latitude location, the location of the sea and land and the level of the terrain, the coastal area is generally an oceanic climate, which is related to the water body, and the Mediterranean climate is more abnormal, with more precipitation in winter, in addition to the warm currents and cold currents caused by the ocean. All have a great impact on the climate.

Water has a regulating effect on the climate. Water vapour in the atmosphere can block 60% of the Earth's radiation and protect the Earth from cooling. Marine and terrestrial water bodies absorb and accumulate heat in the summer, keeping temperatures from getting too high; In winter, heat is released slowly so that the temperature does not get too low.

Water from the ocean and the surface of the earth evaporates into the sky to form clouds, and the water in the clouds falls through precipitation and becomes rain and snow in winter. Water falling on the surface of the earth seeps into the ground to form groundwater; Groundwater emerges from the formations to form springs, which flow into the sea through streams and rivers. A water cycle is formed.

Precipitation activities such as rain and snow have an important impact on climate formation. In temperate monsoon climates, the monsoon brings abundant moisture, resulting in distinct wet and dry seasons.

In addition, in nature, due to different climatic conditions, water also appears in the form of hail, fog, dew, frost, etc., and affects the climate and human activities.

Atmospheric precipitation is the direct result of most terrestrial water bodies, so the runoff of most rivers in eastern China is closely related to the seasonal variation of precipitation, and there are obvious seasonal and interannual variations. Rain-fed rivers have flood seasons that coincide with the seasons of precipitation. However, it is important to note that the flood season is in the rainy season, not in the summer, because depending on the climate type, the precipitation season is not always in the summer.

In the inland areas, rivers are mainly fed by glacial meltwater, so there is a direct correlation between changes in river runoff and changes in temperature, and the flood season of rivers occurs in summer. But it should be noted: the seasons in the northern and southern hemispheres are reversed.

Most of our country has a monsoon climate, so in winter, most of our rivers enter the dry season, and the river water is mainly recharged by groundwater. In addition, it should be noted that lakes have a certain regulating effect on river water. During flood seasons, lakes and reservoirs along rivers play a role in reducing flood peaks.

There is also a water cycle movement within the ocean and on land. The terrestrial cycle forms water vapour through evaporation or transpiration of plants, which condenses to form terrestrial water. This is the terrestrial cycle of water, but neither the spatial domain in which it occurs nor the amount of water involved in it is not as large as the terrestrial water cycle.

Therefore, the water cycle between land and sea has the greatest impact on the natural environment and human beings.

It is the water cycle between sea and land that evaporates ocean water and continuously turns into water vapor and transports it to land, realizing the mutual transformation between marine water, atmospheric water and terrestrial water, maintaining the dynamic balance of global water, and promoting the continuous renewal of terrestrial freshwater resources. Therefore, the ecological environment of the area where the ocean water vapor can reach is full of life. Pleasant natural conditions allow agriculture to be distributed in patches, but also to make the population and cities relatively dense.

This is also an important reason why more than 50% of the world's population currently lives on the coast. It can be seen that the impact of the water cycle between land and sea on the geographical environment and even life on the earth is both extensive and profound.

In the middle of the ocean. When the outside temperature rises, some water molecules evaporate, and these water molecules enter the atmosphere to lower the temperature.

Such water exists in nature. This water increases the humidity of the air, which in turn regulates the climate.

The surface of the globe is composed of 70% of the closed ocean and 30% of the land, and water plays an important role in regulating the climate. Water is stored underground all year round, and water vapor from groundwater and crack-resistant air is circulated.

To put it simply, water has a large specific heat capacity, and a 1 degree Celsius increase absorbs more heat, so you can understand that moisture can help stabilize the temperature. For example, in the desert, the air is dry, and the heat absorbed by one degree is much less than that of water, so during the day, the air will quickly rise to 40 to 50 degrees (but the total heat contained in the air is less), and at night the air will begin to release energy without sun irradiation, and the temperature can drop sharply to 10 degrees or below.

In places with a lot of moisture in the air, water has a high specific heat capacity, can absorb more energy during the day, and the temperature rises slowly (the total heat contained in the air is more), and at night, the air with more moisture releases more heat and cools down slowly.

Water is also an important element of the greenhouse effect, so the biggest effect of water on air temperature is that more water can reduce the temperature difference between day and night. ^_

When the temperature drops, the water will release a lot of heat to alleviate the drop in temperature, and when the temperature rises, the water will absorb a lot of heat to alleviate the rise in temperature.

Therefore, the temperature fluctuations on the seaside are relatively small, and the desert is the opposite, with a large temperature difference.

The main reason is that water is easy to evaporate and volatilize, followed by the large specific heat capacity of water. Because evaporation is the water vapor produced by countless water molecules absorbing heat together, and the water vapor can be in contact with the surrounding air to the greatest extent, so that the water vapor can quickly react to the surrounding temperature difference and quickly produce an effect, and the water vapor is countless water molecules in the production of absorption, emitting heat, so it must be far larger than a single water molecule. Alcohol, for example, can only volatilize, not evaporate, that is, it cannot produce molecular clusters similar to water vapor.

This assumes that the specific heat capacity of alcohol is the same as that of water, and that alcohol regulates the temperature much less than water. Because a single molecule is cold and hot, it is not comparable to water molecules that produce exothermic and endothermic heat absorption. Therefore, the main reason why water can regulate the temperature is that water can produce water vapor and the specific heat capacity is relatively large.
