The reason why the climate in Kunming is like spring all the year round

Lead: Kunming is also called Spring City, which means that the climate in Kunming in Ming Dynasty is like spring all the year round, so it is very livable. Do you know the reason why Kunming is like spring all the year round? What is the reason why the climate in Kunming is like spring all year round? The following is what I have carefully prepared, hoping to help everyone!

The reason why Kunming has four seasons like spring.

Kunming is located in Yunnan-Guizhou Plateau. Due to the high altitude, the temperature in summer and autumn is lower than that in most parts of the country, especially in the morning and evening, which gives people the feeling of spring.

In winter and spring, the warm air mass in the south and the cold air mass in the north meet between Guiyang and Kunming in Yunnan-Guizhou Plateau, forming a "quasi-static front in Kunming". Guiyang, under the control of the cold air mass of the quasi-static front, has formed a rainy and continuous weather with "no sunny days", while Kunming, under the control of the warm air mass of the quasi-static front, is sunny and warm as spring.

Kunming enjoys the reputation of "Spring City", and China is a gateway city open to Southeast Asia and South Asia, and a national historical and cultural city. It is an important tourist and commercial city in China and one of the important central cities in the western region.

Kunming is a mountainous landform, generally high in the north and low in the south. There are many caves and karst landforms, and there are Shilinbazi in karst basin. It belongs to the mountain monsoon climate of the northern subtropical low latitude plateau. The annual average temperature 16.5℃, the annual average rainfall 1450 mm, the frost-free period of 278 days, and the climate is pleasant.

Kunming is surrounded by mountains on three sides and Dianchi Lake on the south. Dianchi Lake is the largest plateau lake in Yunnan Province and the sixth largest freshwater lake in China, with beautiful scenery on both sides. Because it is located in the low-latitude plateau, it has a climate of "four seasons like spring". In particular, Dianchi Lake, a plateau lake, is adjusting its temperature and humidity, making the air here fresh, the sky is high and the clouds are light, the sun is shining, and flowers are always blooming.

There is also a saying in Kunming that "a rain turns into winter", which means that in the cold season, as long as it rains, Kunming will immediately have a strong sense of winter, and the feeling of wet and cold is obvious. The reason for this phenomenon is that Kunming is generally controlled by the heating air mass on sunny days. If the cold air crosses the mountain at the junction of Yunnan and Guizhou and meets the heating mass in Kunming, it will bring rain and cool down.

As a result, the temperature in Kunming fell into a downturn. If the intensity of cold air is high, the temperature in Kunming will drop below freezing point and snowflakes will fly.

Main characteristics of climate in Kunming

1, warm in spring, dry and little rain, vigorous evaporation and large daily temperature difference;

2. There is no intense heat in summer, with concentrated rainfall, heavy rain and storms, and precipitation accounts for more than 60% of the whole year, which is prone to floods;

3. Autumn is cool, the weather is refreshing and the rain is reduced. In autumn, the temperature drops rapidly and the weather is dry. In most areas, the temperature is about 2℃ lower than that in spring. Precipitation is reduced by more than half compared with summer, but it is more than winter and spring, and autumn drought is rare;

There is no cold in winter, with plenty of sunshine, sunny weather and little rain.

5. The dry season and the rainy season are completely different. The annual precipitation is obviously divided into dry season and wet season in time distribution. May ~ 10 is the rainy season, and the precipitation accounts for about 85% of the whole year. The dry season is 1 1 to April of the following year, and the precipitation only accounts for about 15% of the whole year.

The characteristics of Kunming all year round

summer

Kunming is located in Yunnan-Guizhou Plateau, with an altitude of about 2000 meters. When the altitude rises 100 meters, the average temperature drops by 0.6 degrees Celsius, and the water in Dianchi Lake can absorb heat in summer. Moreover, influenced by the Indian Ocean airflow, there is more precipitation, which makes the average summer temperature in Kunming 65,438+06℃-24℃.

winter

Kunming is sunny and surrounded by mountains on three sides. Due to the long distance and the blocking of the terrain, the average temperature in Kunming in winter is 4℃- 16℃, making Kunming a real summer without heat and winter without cold.

In a word, the climate in Kunming is warm and pleasant, because it is like spring all the year round. It has a famous "Spring City" in China.

The earth is divided into four seasons, mainly because of its rotation and its revolution around the sun. The ecliptic plane produced by the revolution of the earth forms an angle with the equatorial plane produced by the rotation of the earth, which is called the ecliptic angle.

The existence of the yellow-red intersection angle makes the direct point of the sun move only between the tropic of cancer. Every year, the vernal equinox and autumnal equinox make the sun shine directly at the equator, and the northern hemisphere divides the day and night equally, while the summer solstice makes the sun shine directly at the Tropic of Cancer, with the longest day in the northern hemisphere and the opposite in the southern hemisphere.

From the vernal equinox to the autumnal equinox, the days in the northern hemisphere are long and the nights are short. From the autumnal equinox to the vernal equinox, the days in the northern hemisphere are short and the nights are long. As the earth revolves around the sun, it moves according to this law every year, so there is a phenomenon that the earth has four distinct seasons.

However, not all parts of the earth have completely different seasons. There is no winter in low latitudes, such as near the equator, and there are only winter and summer in high latitudes, but there is no spring and autumn. Only temperate regions have four different seasons.

What makes us even more proud is that the 24 solar terms, a knowledge system formed by our ancestors in ancient times by observing the annual movement law of the sun, have been recognized as intangible cultural heritage by UNESCO.
