今年6月末,由于太平洋副热带高压增强西伸北抬,脊线稳定于北纬23度附近,加之西北冷空气的不断侵入,冷暖空气交汇于淮河流域上空,致使淮河流域连降暴雨。淮河干流及淮北主要支流水位猛涨,内涝严重,部分地区发生了较大的洪涝灾害,初步统计流域内直接经济损失达16亿元左右。 At the end of June this year, due to the enhancement of the western subtropical high in the Pacific Ocean, the ridge line stabilized at a latitude of 23 degrees north latitude. Combined with the intrusion of cold air in the northwest, cold and warm air converged over the Huaihe River Basin, causing continuous heavy rains in the Huaihe River Basin. Huaihe River and the main tributaries of Huaibei water level soared, serious waterlogging, flood disaster occurred in some areas, the preliminary statistics of direct economic losses within the basin reached 1.6 billion yuan.
