N, the north of Zhejiang is on 24-25. And is stable for five days or more. After continuous rainy days, there is basically no rain for seven days or more in southern Zhejiang and five days or more in northern Zhejiang (excluding precipitation caused by tropical system in the south and local geothermal thunderstorms). The average daily temperature is stable at 25 degrees. C or 25. Above C.

The daily average temperature and pressure time curve of a single station have increased synchronously. If the subtropical ridge has jumped northward to 25. N, and stable for two hours, during which the continuous rainy weather is still greater than or equal to 0. 1 mm, then all days with daily rainfall greater than or equal to 1.0 mm are selected. 120- 130 after the rainy season.

C, and there is no rain for more than 6 consecutive days.

The average annual flowering date of plum blossoms is July 9. When the ridge line of subtropical high jumps northward to 26.
