Which monsoon belt does Weihai belong to?

Shihai belongs to the continental climate of north temperate monsoon, with obvious seasonal changes and monsoon advance and retreat. Compared with inland areas at the same latitude, it has the characteristics of abundant rainfall, moderate annual temperature and mild climate. The continental degree of Weihai is 54. 1%. Being close to the Yellow Sea and regulated by the ocean, Weihai has the characteristics of maritime climate, such as cool in Leng Xia in spring, warm in autumn and warm in winter, small temperature difference between day and night, long frost-free period, strong wind and high humidity.

spring

From March to May, warm air began to be active, but cold air still had considerable influence, which led to frequent movement and alternation of high and low pressure systems and changeable climate. From April to May, strong winds alternate from north to south, which is a windy month all year round. The temperature is low, rising slowly, 2-3℃ lower than that in the inland areas of the same latitude, and the season is delayed by about half a month. Because warm and humid air cannot be transported in large quantities, the precipitation is still very small, accounting for only 14% of the total precipitation in the whole year. Because of the strong wind, less precipitation and large evaporation, spring drought often occurs.

summer

(June-August) Due to the adjustment of the ocean, the temperature is low. June-July is 3-4℃ lower than inland latitude, and August is 65438 0℃ lower. The cool and pleasant climate makes Weihai a famous summer resort. The highest temperature is in August, and the extreme highest temperature in the whole year appears in July and August. With the strengthening of the Pacific high northward, the summer monsoon begins, mostly with the south to southeast wind of grade 3-4, which is beneficial to warm and humid air northward, so there is much precipitation and high humidity, and the precipitation accounts for 59% of the whole year. The flood season begins in late June and early July and ends in early September. Heavy rains are concentrated in July, August and early September, and frequent heavy rains often lead to floods. However, in some years, due to the control of the Pacific high, Shandong Peninsula is stable and inactive, resulting in high temperature, high humidity and sultry weather, resulting in short-term drought. Due to the guidance of atmospheric circulation, typhoons in the Pacific Ocean move northward, often causing heavy rain and windy weather.

autumn

In early autumn (September-165438+1October), the cold air in the north began to be active, but the warm and humid airflow still had some influence, so there was still a lot of rain in early September, and sometimes it rained continuously, which might be hit by a typhoon. The total precipitation in autumn accounts for 23% of the whole year, mostly concentrated in September. From late September to 10, the cold air in the north strengthened and the warm and humid air flow decreased obviously. The temperature is higher in the whole autumn, and it is slightly higher in September than in inland areas of the same latitude, 10-1-2℃. On June 5438+ 10, the weather is clear and the visibility is the best, but autumn drought often occurs. From the middle of 165438+ 10, a strong Mongolian high began to establish and cold air became active. The temperature drops rapidly with a temperature difference of 3℃ every ten days, the number of northerly winds increases, and the winter wind becomes more and more obvious.

winter

(12-February) controlled by the strong Mongolian high pressure, cold air broke out southward continuously, and the climate was dry and cold, mostly northward. Weihai and Yantai are called snow nests. 65438+ 10 is the coldest month in the whole year, and the extreme minimum temperature of the whole year generally appears in 65438+ 10 or early February. The temperature in the whole winter is 2℃ higher than that in the inland areas of the same latitude, and the temperature difference between day and night is small. Seasonal precipitation is the least in the whole year, accounting for 5% of the whole year. From the end of June to May 438+February, due to the influence of the ocean, the local cloudy and snowy weather increased, the amount of rain and snow was more than three times that of inland areas at the same latitude, and the sunshine hours were less.
