Why are the seasons like spring in Kunming, Yunnan?

The topography of Yunnan inclines from northwest to southeast. Kunming is located in the central and eastern Yunnan, and the terrain gradually decreases from north to south. The east, west and north of the city are surrounded by mountains, while the mountains in the south are low and far, so the warm and humid airflow from the Indian Ocean in winter is blocked by mountains, which makes it difficult to invade, so it is warm as spring in winter. In summer, the Yunnan-Guizhou Plateau, where Kunming is located, has a high altitude, a relatively dry climate, and the air is not easy to accumulate heat. The surrounding vegetation of Kunming is rich and the climate is cool. In addition, there are many natural adjustments such as Dianchi Lake, Fuxian Lake and Yangzonghai near Kunming. A variety of reasons have formed the climate of Kunming, which is warm in winter and cool in summer, with four seasons like spring.

Why is the weather in Kunming like spring all year round?

Colorful flowers do not fade, warm in winter and cool in summer. "

The climate of Kunming enjoys the reputation of "Spring City". There is no severe cold in winter, no intense heat in summer, and the four seasons are like spring. July is the midsummer season in most parts of the country, but Kunming still seems to be full of spring. The average temperature here in July is only about 20℃, which is 8℃ lower than that in Guilin at the same latitude. June 5438+ 10, most of the country is in the middle of winter, but Kunming has a hint of spring, and the average temperature is close to 10℃. It is rare that it snows there. The annual average temperature in Kunming is about 65438 05℃. Due to the mild climate, abundant rainfall and lush plants, flowers bloom all year round. There is a saying that "Spring City is full of flowers". Therefore, the title of "four seasons like spring" is really worthy of the name for Kunming.

Why are the seasons like spring in Kunming?

We know that the higher the terrain, the lower the temperature. Kunming is located in Yunnan-Guizhou Plateau, with an altitude of nearly 2000 meters. Although it is close to the tropics, its height offsets its low latitude, which is the main reason why it is cooler in summer.

Another reason is that Kunming is in the southwest of China. In summer, there is a southwest monsoon from the Indian Ocean, which brings a lot of steam and often rains. Clouds and rain weaken the solar radiation, and the evaporation of rain also takes away a lot of heat, so the ground temperature is not high.

In winter, due to Kunming's low latitude (25 degrees north latitude), the solar radiation is relatively strong, and there is a southwest warm current from the southwest of the Asian continent to send heating to Kunming. Under the influence of the dry southwest warm current, the dry season is formed, with clear weather and little rain, so there is plenty of sunshine and mild climate.

In addition, Kunming is located in the plateau, and there are Wangliangshan and Wumeng Mountain in the north to block the invasion of cold air from north to south, so there are few cold days in winter.

Kunming has four seasons like spring and a pleasant climate, which is conducive to agricultural and animal husbandry production. Crops are harvested twice a year, and warm crops such as rice, tea and cotton can be planted. Because the temperature there does not change much, it is especially suitable for the production of precision machines and instruments. In recent years, the machine tools and optical instruments produced in Kunming have become famous all over the country.

Kunming is located in Yunnan-Guizhou Plateau, with an altitude of nearly 2000 meters. Although it is close to the tropics, the altitude offsets the influence of low latitude. This is also one of the reasons why it is cooler in summer; Kunming is in the southwest of China. In summer, there is a southwest monsoon from the Indian Ocean, which brings a lot of water vapor and often rains. Clouds and rain weaken the solar radiation, and the evaporation of rain also takes away a lot of heat, so the ground temperature is not high. In winter, due to the low latitude (25 degrees north latitude) in Kunming, the solar radiation is relatively strong, and there is a southwest warm current from the southwest of the Asian continent to send heating to Kunming. Under the influence of the dry southwest warm current, there is plenty of sunshine and little rain, so there is plenty of sunshine and a mild climate. There are Wangliangshan Mountain and Wumeng Mountain in the north of Kunming, which block the invasion of cold air from north to south, so there are few cold days in winter.

Why is the climate in Kunming like spring all the year round?

The climate in Kunming has no obvious four seasons, and it is basically warm, so the weather is called four seasons like spring.

The reason why Kunming has four seasons like spring.

This is determined by the geographical location and topographical features of Kunming. Kunming, located south of 30 degrees north latitude, receives more and more sunlight and heat from the sun all year round. In summer, due to the influence of warm and humid air currents in the southwest and southeast winds of the Indian Ocean, it rains continuously, clouds and rains weaken the solar radiation, the sunshine is less, the ground humidity is not easy to rise, and the evaporation of rain also takes away a lot of heat. Coupled with the Yunnan-Guizhou Plateau, which is located at an altitude of 1000 meters above sea level, the temperature decreases with height, so the temperature will not be very high in summer. West winds prevail in Kunming and other places in winter. The airflow here guides the dry and warm air from the nearby Indian Peninsula. In addition, Kunming is located in the east of Yunnan, and the mountains in the north and east of Yunnan, such as Wangliangshan and Wumeng Mountain, can block the cold air from the north from going south, so there are many sunny days, dry air, abundant sunshine and high temperature.

It is not hot in summer, not cold in winter, and the temperature in the four seasons is relatively uniform.

Read the passage and answer the questions. Why are the seasons like spring in Kunming? This is determined by the geographical location and topographical features of Kunming. Kunming is in the north.

1.C 2。 D 3。 One reason why the temperature will not be very high in summer. Kunming is located in the east of Yunnan, and the mountains in the north and east of Yunnan can block the cold air from the north from going south.

People often say "Kunming" and "four seasons are like spring". What does this mean?

Explain that the climate in Kunming is good, and the seasons are like spring!

Is it true that Kunming has four seasons like spring?

Why is it not cold in winter only in Yunnan? Let's look at an example first.

Kunming, the capital of ancient Yunnan Province, was known as "an unbeaten city in spring, warm in winter and cool in summer". Kunming and Guilin in Guangxi are at the same latitude. The average temperature in January in the two places is basically the same, both around 7.8℃, but the altitude of Kunming is1892m, which is higher than that of Guilin1720m! If the vertical gradient of winter average temperature in Yunnan drops by 0.45℃ for every rise 100 m, and Guilin is corrected to the same altitude as Kunming, the average temperature in Kunming 1 month will be only 0℃. Conversely, if the temperature in Kunming is corrected to the height of Guilin, Kunming is also 7.8℃ higher than Guilin, that is, 15.6℃.

Why is Yunnan cold? Why is Yunnan particularly warm in winter?

Yunnan is warm in winter for a reason, such as the land and the sky. First of all, there are tall mountains in eastern Yunnan, such as Wumeng Mountain, which block the cold air from Siberia from north to south and then to west. But even this would not be enough In winter, the dry and warm westerly airflow from southwest Asia prevails over Yunnan. The higher the airflow, the stronger it is (westerly jet at high altitude). So the mountain was blocked, the westerly airflow was blocked, and the heavens and the earth joined forces to finally block the cold air in the east of Yunnan Plateau. Yunnan is often bathed in warm westerly airflow in winter, which is naturally warm as spring. The eastern part of China, such as Guilin, is naturally colder because it is often "soaked" by the cold air sea going south frequently. This is why the eastern part of China at the same latitude has a subtropical climate, while the Yunnan Valley has a tropical climate. When winter came to Yunnan, the north wind in the eastern region roared south, and the temperature plummeted in a large area. Yunnan was still sunny, just like living in another world and having a paradise.

Yunnan is not only rich in animal and plant resources, but also a province with strong local climate characteristics in China.

Xishuangbanna in southern Yunnan is very warm in winter, and the temperature difference between winter and summer is greatly reduced, but the rainy season and dry season are very clear. So, like Indochina Peninsula in the south, the whole year is divided into dry season (11-March), hot season (April-May) and rainy season (June-September), that is, three seasons a year.

Plants are flourishing in most parts of Yunnan, but the hunger is the highest in the northern part of Hengduan Mountain. The foehn effect caused by mountainous areas makes regional dry valleys appear in Jinsha River. For example, the annual rainfall of Benzilan in Deqin County is only 336 mm (the annual rainfall of Gongshan, which is only 85 kilometers southwest, is 1667 mm).
