Who knows the weather in Kunming, Yunnan all year round?

Kunming is located in the middle of Yunnan-Guizhou Plateau, with a geographical location of120 45 ′ east longitude and 25 2 ′ north latitude. Altitude of downtown 1, 89 1 m. Dianchi Lake is in the south and surrounded by mountains on three sides. "The city is surrounded by mountains and lakes, and the landscape is comparable to painting." It belongs to the monsoon climate of low latitude plateau and mountainous area. Affected by the warm and humid airflow in the southwest of the Indian Ocean, the sunshine is long, the frost period is short, and the annual average temperature is 15 degrees. The climate is mild, with no heat in summer, no severe cold in winter, four seasons like spring and pleasant climate. "The weather is often like February and March, and flowers are always in spring." This is a very famous "Spring City".

"Colorful flowers don't thank, warm in winter and cool in summer." Kunming has a humid climate, with full of green all the year round, and the flowers are constantly blooming, and the seasons are like spring. The favorable climatic conditions make more than 400 kinds of flowers open in Kunming, covering an area of 15000 square kilometers, among which camellia, orchid, rhododendron and primrose are well-known at home and abroad. Kunming Botanical Garden is a gathering place for plants and flowers, with nearly 4,000 species of tropical and subtropical plants, among which camellia is the most famous. Local products include coffee, coconut sugar, crushed coconut, natural coconut juice, coconut sauce, bananas, pineapples and jackfruit. Climate: Kunming is located in the low-latitude plateau, with complex and diverse landforms, great topographic differences and obvious vertical and horizontal differences in climate. In the mountainous area, there are scenes of "flowers bloom under the mountain and snow falls on the mountain" and "Yongshan is divided into four seasons, and ten miles are different from the sky". According to the statistics of meteorological data since the founding of the People's Republic of China, the annual average temperature in Kunming is 14.5℃, the average temperature in the hottest month (July) is 19.7℃, and the average temperature in Leng Yue (65438+1October) is 7.5℃, and the annual temperature difference is12 ~/kloc. The annual precipitation is about 103l mm, and the relative humidity is 74%, with little humidity. In recent years, the frost-free period has been more than 240 days. There are many sunny days throughout the year, with annual sunshine hours of 2445.6 hours and sunshine rate of 56%. The annual projection angle of the sun is large, and the annual average total radiation is 129.78 kcal/cm2, of which 62.78 kcal/cm2 in rainy season and 67 kcal/cm2 in dry season, with little change in two seasons. Therefore, the poet Yang Shengan praised Kunming for "the weather is often like February and March, and flowers are always in spring". Climate characteristics: Kunming is located in the subtropical zone of north latitude. However, most areas in China have typical temperate climate characteristics and are known as "Spring City" at home and abroad. The main features of the climate in Kunming are as follows. 1. Spring is warm, dry and rainy, with strong wind and strong evaporation, and the daily temperature changes greatly. In spring, the airflow comes from the tropical continent, with plenty of sunshine, and the average monthly temperature is mostly below 20℃. But the temperature difference between day and night is large, which has the characteristics of "spring in the morning, summer in the afternoon, autumn in the evening and winter in the middle of the night". There is little precipitation in spring, low air humidity, large evaporation and rapid temperature rise, which makes agricultural production vulnerable to drought, which is not conducive to the growth and sowing of crops in spring. 2. There is no intense heat in summer, the rainfall is concentrated in summer, the airflow comes from the tropical ocean, it is rainy and cloudy, the water is sufficient, the soil is moist, and the solar radiation absorbed by the ground is reduced, so the radiation heat is used for water evaporation. Therefore, in midsummer, except for areas below 1600 meters above sea level, the average temperature can reach the summer standard of 22℃ in about two months, and most other areas belong to the spring climate below 2 1℃, so there is no hot summer period. Summer rainfall is concentrated, with heavy rain and heavy rain, and precipitation accounting for more than 60% of the whole year, which is prone to floods. 3. The air is crisp in autumn, the weather is crisp, the rain is reduced, and the temperature drops rapidly in autumn during the frost period, and the weather is dry. The temperature in most areas 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. Generally, the rainy season ends in the first half of June 65438+1October, and the first frost period begins in the first half of June165438+1October. There is no severe cold in winter, and there is plenty of sunshine. It is sunny and rainy. In winter, the average sunny day is about 20 days, sunshine is about 230 hours, and rainy day is about 4 days. The precipitation in the whole season only accounts for 3% ~ 5% of the whole year. Except for the valley area below 65,438+0,5500m m, the winter lasts for more than two months in most areas of the city (the five-day average temperature is lower than 65,438+00℃), and sometimes there will be cold weather, frost or snowfall, which may cause crops to suffer in early spring. 5. The dry season and the rainy season are completely different. In terms of time distribution, the annual precipitation is obviously divided into dry season and rainy season. 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. In April and May, the precipitation 10 and 1 1 changed greatly. The precipitation in May is two or three times more than that in April, and 1 1 monthly precipitation is more than that in June 1 times.
