Comparison of climate in Jingdezhen, Jiangxi, Yibin, Sichuan and Zunyi, Guizhou all year round!

Zunyi city is particularly affected by monsoon. Winter and spring seasons are mostly affected by cold waves or cold air in the northern hemisphere, and winter winds are generally northeast or easterly. When Zunyi is affected by the northeast monsoon, the clouds are thick and low, and the radiation of the cloud top cools down at night, which often produces night rain. If the southerly airflow meets the northerly airflow between Sichuan and Guizhou, it will often form a Yangtze River shear line at an altitude of 3300 meters, or a quasi-static front in the surface layer, and the rainy weather will be longer. In mid-April, the southwest monsoon moved northward, cloudy weather decreased, cloudy days increased, and the temperature increased significantly. Due to the low latitude and strong sunshine in Zunyi, the temperature may rise above 30℃ for three consecutive days.

Due to the northward summer monsoon (southwest airflow), the water vapor swept from the Bay of Bengal and the Indian Ocean increased greatly, and Zunyi entered the rainy season around April 16, with frequent moderate to heavy rains. From May to June, the summer monsoon moved to the Yangtze River basin and met with the northerly airflow, resulting in rainy weather in the Yangtze River basin. Zunyi City is located in the upper reaches of the Yangtze River, which also produces heavy rainfall and frequent rainy weather. The summer monsoon continues to strengthen, and the southwest airflow continues to push north. Zunyi city is controlled by the pure southwest monsoon, and the rainy weather begins to end, and it enters sunny, high temperature and dry weather with little rain. In mid-September, the summer monsoon gradually weakened and retreated southward, and the winter monsoon gradually strengthened southward, and Zunyi began to experience continuous autumn rain. In the future, when the winter wind basically controls Zunyi, it turns cloudy and gloomy.

Zunyi City is located in the low latitude, and the cold air from Siberia greatly weakens its degeneration, so the extreme minimum temperature in the coldest winter period of 65438+1October is only-7.1℃ (197765438+1October 30th), which is 0.2 higher than that in Zhijiang at the same latitude. Summer is often influenced by the southwest monsoon, and the extreme maximum temperature in the hottest period over the years is only 38.7℃ (1953 August 18), which is lower than the neighboring Chongqing's 40.4℃ 1.7℃. The annual average temperature in Zunyi 15. 1℃ is 0.6℃ higher than that in Kunming. Therefore, Zunyi City has no severe cold in winter, no intense heat in summer, abundant rainfall and pleasant climate.

Spring (March-May): It is warm and windy in spring, but sometimes it is cold; The seasonal average temperature is about 15.3℃, and the total precipitation is close to 300mm. In spring, the temperature warms up early and sunny days increase. Generally, it passes through the first day of ≥ 10℃ in early April, but the climate is extremely unstable, and there is often late spring cold from late March to early April. Due to the frequent intersection of cold and warm air, hail occurs in April and May, which will bring serious disasters in some years. The rainy season usually begins in the middle and late April.

Summer (June-August): rainy in early summer, dry in midsummer, hot but not cold; The seasonal average temperature is about 24.65438 0℃, and the total precipitation is 400~500mm. The extreme maximum temperature appeared in late July, reaching 37.4℃, but the high temperature weather of ≥35℃ was only 1 ~ 5 days. Summer is the season with the most rainfall in the whole year, especially in early summer and June, which is the time with the most rainfall in a year. Heavy precipitation weather occurred, and severe floods occurred in some years. From July to August in midsummer, it is often controlled by the western Pacific subtropical high, and there is often a summer drought.

Autumn (September ~165438+1October): the temperature drops suddenly in autumn, and the autumn wind drizzles; The seasonal average temperature is about 16. 1℃, and the total precipitation is 240 ~ 280 mm In autumn, due to the sharp weakening of summer monsoon and the south wind in winter, the rainfall is obviously reduced, the temperature is obviously reduced, and the number of rainy days is gradually increasing. Autumn wind appeared in early September, and from mid-September to mid-June of 10, rainy weather appeared in more than half of the years, and rainy years also affected the production of Sanqiu. The rainy season usually ends in the middle and late June of 10.

Winter (12 ~ February): There is no severe cold, little rain and occasional freezing in winter. The seasonal average temperature is about 5.5℃, the total precipitation is 60 ~ 70 mm, and the extreme minimum temperature appears in late June of 1, reaching -7. 1℃. In winter, due to the frequent cold air activities, the static front of Yunnan and Guizhou often forms, resulting in more rain and less sunshine in our city, which is the season with the least radiation throughout the year. The coldest period often occurs in 65438+ in the middle of winter 10 month, and it is often accompanied by freezing.

Yibin city belongs to subtropical humid monsoon climate, and the low mountains, hills and valleys have the climate attribute of south subtropical zone. It has the characteristics of mild climate, abundant heat, abundant rainfall, suitable illumination, long frost-free period, warm winter and early spring, and distinct four seasons. The annual average temperature is about 18℃, and the annual average precipitation is 1, 050- 1, 618 mm. May to 10 is the rainy season, and the precipitation accounts for 8 1.7% of the whole year. The main flood season is from July to September, and the rainfall is relatively concentrated. The annual average sunshine 1000~ 1 130 hours, and the frost-free period is 334~360 days. The annual average wind speed is only 1.23m/s, mostly northwest wind and northeast wind. The static wind frequency is relatively high, reaching 34-53%, and the wind speed is small.

Jingdezhen belongs to subtropical monsoon climate, with abundant sunshine, moderate and humid rainfall, distinct seasons, overlapping peaks and mountains, dense rivers, mountains surrounded by water and beautiful scenery. According to the latest meteorological data 198 1-20 10, the annual average temperature in Jingdezhen is 17.8℃, the annual average rainfall is 1805 mm, and the extreme maximum temperature since meteorological records. The climate in Jingdezhen is changeable in spring, with cold days and warm days. The rainfall is concentrated in the rainy season before summer, and the rainstorm is disastrous and frequent. The average annual precipitation in May, June and July is 200-350 mm, which is easy to cause floods. After plum blossom, it is mostly controlled by subtropical high. The weather is hot and the humidity is high, which makes people feel sultry. In autumn, the temperature is mild and there is little rain; Winter is often influenced by Siberian (or Mongolian) cold high pressure, prevailing northerly winds, and the weather is cold and gloomy.

Winter smog heating in the south, Yibin is recommended, which is relatively better.
