Characteristics of Summer Temperature Distribution in China

The summer temperature distribution in China is characterized by high temperature in the north and south.

In summer, the temperature in the north and south of China is generally high, and the average temperature is mostly above 20℃. Because the sun has a high angle at noon in the south, but the day is short, the heat obtained on the ground is not much different from that in the north. The Qinghai-Tibet Plateau, with its high terrain and thin air, has the lowest temperature in summer in China.

The main causes of high temperature weather in China in summer are as follows:

1. Solar radiation: In summer, the direct point of the sun is in the northern hemisphere. In the north of China, the height angle of the sun at noon is small, and the day is long, so the heat obtained on the ground is not much different from that in the south. In the south, the sun has a high altitude angle at noon, but the daytime is short, and the ground gets a little more heat than in the north, so it shows the characteristics of high temperature in the whole country.

2. Seasonal movement of the wind belt in the pressure belt: in summer, the subtropical high belt moves northward, and the temperature in the area controlled by the subtropical high is high.

3. Summer monsoon: The southeast monsoon from the Pacific Ocean and the southwest monsoon from the Indian Ocean bring humid airflow, which increases precipitation and lowers temperature.

The above are the main reasons for the high temperature weather in summer in China, but it does not mean that it will happen every summer. Climate change is a complex process, which is influenced by many factors.

The impact of global warming on the global climate;

1. temperature rise: global temperature rise leads to melting of polar ice and snow and glaciers, which in turn leads to rising sea level, which has serious impacts on low-lying areas such as coastal cities and islands, such as floods, coastal erosion and inundation.

2. Increased extreme weather events: Global warming may increase the frequency of extreme weather, such as drought, flood and extreme temperature, affecting the survival of living things, and precipitation in low latitudes may decrease, which has a great impact on agriculture.

In addition, global warming will also provide air and ocean kinetic energy, resulting in super-large disasters such as typhoons and tsunamis, and more and more disasters are faced every year. At the same time, typhoons and tsunamis will also destroy buildings, threaten human life, bring mudslides and landslides, and cause great hidden dangers to mankind.

3. Loss of biodiversity: Global warming will also have an impact on ecosystems. Rising temperature will affect the growth and reproduction of animals and plants, and affect species diversity. At the same time, global warming will also lead to changes in habitats, such as changes in polar ecosystems.

4. Economic and social impact: Global warming will also have an impact on economy and society, such as agriculture, fisheries, tourism and energy, as well as human health and social stability.
