Yesterday (24th), an obvious rainfall zone was formed from Guangxi to the south of Susong. In some areas, rainfall was heavy and heavy rain occurred. According to the monitoring of the Central Meteorological Observatory, from 14:00 on the 23rd to 14:00 on the 24th, heavy rains occurred in the northwestern and western Guangxi, southern Hunan, parts of Jiangxi, central and southern Anhui, southern Jiangsu, and southern Zhejiang. At the same time, there were heavy rains or heavy rains in southwestern Yunnan, and the rainfall in Yunnan Bohai reached 182 mm. The strong invasion of rainfall made the hot weather difficult to emerge. On the 24th, the temperature in the south was basically lower than 35 °C. Only Sichuan and Chongqing had a temperature of 35 °C, and the rest were cooler.
Affected by the subtropical high shear line, from August 14th to 22nd, there were widespread heavy rainfall in Shandong Province, heavy rains in Lubei, Luzhong and Lunan, and parts of the peninsula. Heavy rains occurred in northwestern Shandong, accompanied by local areas. 8 winds. The average rainfall in Guancheng County of Liaocheng City and Taishan District of Tai'an City is over 150 mm. Due to the continuous rainfall, the farmland is saturated with water, heavy rain and strong winds cause large areas of cotton, corn and other crops to be flooded and lodging, and some houses are damaged. The affected area of ​​the crops was 150,000 hectares, of which 22,000 hectares were not harvested.
At present, the spring wheat in the northeastern region has been harvested. The meteorological conditions in the wheat growing season are favorable, and the active and effective technical measures are taken in the selection of wheat varieties, planting density, pest control, etc. Spring wheat in the northeast region has a good harvest year. The growth process of other autumn grain crops is normal, and the growth is better than the same period of the previous year. If there is no major natural disaster in the later period, the grain production in Northeast China will be harvested again.
Since mid-August, the spring wheat in Qinghai agricultural area has generally entered the milk ripening or maturity stage, while in most of Qinghai Province, there are more precipitation processes and more than 30% precipitation. The harvest of mature spring wheat has a relatively large impact. Due to the continuous soaking of rainwater, the harvested spring wheat cannot be dried and stored due to continuous rainy weather, and moldy and long buds appear. However, the spring wheat that has not yet been harvested has a large area of ​​lodging, which makes the harvester unable to harvest, affecting the harvest of wheat, and the moldy long buds of wheat are no longer edible, which has a great impact on wheat yield.

Most of Inner Mongolia and Northwest China are in the stage of filling milk mature to maturity, and some are in heading stage. Since mid-August, most of the central and eastern parts of the northwestern region have been at or near normal temperatures, with more precipitation, which is conducive to soil growth, which has eased most of the drought in the dry areas, and is more favorable for the growth and development of pasture and autumn harvest crops; Harvested spring wheat has an adverse effect.
The Central Meteorological Observatory estimated at 18:00 on the 24th that in the next 24 hours, rainfall in the southern region will be weakened. There are moderate to heavy rains in the eastern part of the Yangtze River, central and eastern South China, and southern Yunnan. The rainfall is generally 10 to 20 mm and the local area is 25 to 35 mm.

Specific forecast for the next three days
From 08:00 on the 25th to 08:00 on the 26th, there were moderate to heavy rains in parts of northeastern Shanxi, northwestern Hebei, central and eastern Jianghuai, eastern Jiangnan, southwestern Guangdong, southeastern Guangxi, southwestern Yunnan, and western Sichuan Basin. The rainfall is generally 10 to 20 mm, with a local area of ​​30 to 40 mm; some of the above areas are accompanied by strong convective weather such as short-term thunderstorms and strong winds.
From 08:00 on the 26th to 08:00 on the 27th, there were moderate to heavy rains in the western Tianshan Mountains of Xinjiang, eastern Shanxi, central and eastern Huanghuai, southeastern Jianghuai, northeastern Jiangnan, southwestern Guangdong, southwestern Sichuan Basin, western Yunnan and southern China. Generally, it has 10 to 20 mm and a part of 30 to 40 mm. The above areas are accompanied by strong convective weather such as short-term thunderstorms and strong winds.
From 08:00 to 28:00 on the 27th, there were moderate to heavy rains in parts of western Tianshan Mountains, central and eastern Huanghuai, central and eastern Jianghuai, northeastern Jiangnan, southwestern Guangdong, and southwestern Yunnan. Among them, southeastern Shandong and northeastern Jiangsu There are heavy rains in the local area, the rainfall is generally 10 to 25 mm, and the local temperature is 40 to 60 mm. The above areas are accompanied by strong convective weather such as short-term thunderstorms and strong winds. There will be 6-8 winds in the east of Taiwan.
Agricultural advice
Jiangnan, Huaihe, Huanghuai and other places should do well in response to local convective weather disasters such as thunderstorms and strong winds, and mitigate disaster losses. Timely opening and draining channels to strengthen field management. The dry area pays attention to catching the opportunity of precipitation to do the water storage work, rational irrigation, and alleviate the adverse effects of drought on crops. The area that has entered the mature harvesting period, pay close attention to the weather changes, grab the favorable opportunity, harvest and grind in time, and strive to return the grain. In areas where spring wheat is not yet fully mature, attention should be paid to strengthening field management to create favorable conditions for increasing the seed setting rate and 1000-grain weight of wheat.
