Every year in Shanghai, it is 65438+ 10. Early October to early February is the middle of winter, which is the coldest time of the year. When the strong cold air in the north moves southward in stages, there will be a strong wind from north to northwest and a short-term strong cooling process. The weather will be fine, cold and dry, and the extreme minimum temperature at night will be around -5℃~0℃. However, the medium-intensity cold air in the north frequently supplements southward, and the warm and humid airflow in the southwest is relatively active, which is prone to long-term low-temperature and rainy weather, with very insufficient sunshine, weak winds from the north to the northeast and cold and humid weather. In the middle and late February, the temperature began to rise slowly and the chill subsided slightly. In the middle and late March, Shanghai entered the spring and the temperature fluctuated obviously. By April, the extreme maximum temperature can sometimes reach more than 30℃ (33.5℃ in recent years and 34.3℃ in 2004), but the second-highest period of cold wave in Shanghai is from mid-late February to early April, with large-scale invasion of cold and high pressure in the north. The weather is hot and cold, sunny and rainy, and the weather situation is unstable, which is the most dramatic period of temperature change throughout the year.

In May, Shanghai gradually transitioned to strong convective weather such as summer and thunderstorm. From May to early June, Shanghai is still in the early summer season, mainly sunny and hot weather, but the highest temperature is around 30℃~34℃, so there will be no high temperature disaster. In mid-June, Shanghai gradually entered the rainy season, and the weather was controlled by the cold trough in the northern part of the Meiyu belt in the south of the Yangtze River. In the middle and late period, Shanghai jumped with the Meiyu belt to the north and in the Jianghuai Meiyu belt to the south. The weather in Shanghai is humid and sultry. During the strengthening of subtropical high, there will be obvious thermal and high temperature gaps between heavy precipitation occasionally. The first wave of high temperature often rises at this time of year. In early July, Shanghai bloomed, controlled by the northwest side of the strong subtropical high. From sunny and hot weather with little rain, dry and hot airflow prevailed from south to southwest, and the extreme maximum temperature was around 37℃~39℃.
