From late March to early April, moderate to severe drought occurred in most wheat areas in central and southern China, which inhibited the growth of winter wheat. Since June, high temperature, little rain and uneven distribution in most parts of the province have hindered the growth of corn, millet, sorghum and other crops, and the fruit setting rate of apple, pear and other fruit trees is low, and the drought continues to develop. Up to now, the drought has affected 29 counties in Linfen, Changzhi, Lvliang, Yuncheng, Taiyuan, Xinzhou and Jinzhong1465,000 people,154,000 people need life assistance due to drought, among which142,000 people need assistance due to drinking water difficulties; The affected area of crops is about 307.3 thousand hectares, of which 26.6 thousand hectares will not be harvested; There are about193,000 large livestock with difficulty in drinking water; The direct economic loss reached 1.2 1 100 million yuan.

Only a few months in summer can be affected by the warm and humid air currents in the ocean, and there is only one rainy season in a year, which is short. At other times, it is mostly controlled by the dry continental air mass, and the drought period is particularly long and the precipitation is very scarce. Therefore, from the overall situation of the whole year, some areas of Shanxi Province may be relatively dry, especially in the northern part of Shanxi Province. From spring to early summer, it is in a dry period, and the precipitation increases very little. The average rainfall in ten days before mid-May is below 10 mm, and from late May to late June, the rainfall in each ten days is only 10? 20 mm.
