Rainfall extremes have been broken in many parts of northern China, with a marked level of extremity.
According to a report by China News Service, journalists learned from the China Meteorological Administration on Saturday (July 26) that since July 23, many northern regions have been continuously affected by heavy rainfall, with Inner Mongolia, northern Hebei, Beijing, and the area in front of the Taihang Mountains becoming the core zones of heavy precipitation.
On the 25th, heavy rainfall continued in Inner Mongolia and Hebei. In parts of Zhangjiakou and Baoding in Hebei, as well as Hohhot, Ulanqab, Xilingol, Chifeng, and Tongliao in Inner Mongolia, extremely heavy rain occurred. In Kangbao (Zhangjiakou) and Fuping (Baoding), Hebei, extraordinarily heavy rain was recorded (269mm to 375mm). From 9 a.m. on the 24th to 8 a.m. on the 25th, the 24-hour rainfall in Yixian County, Baoding, Hebei reached 362.6 millimeters, resulting in severe waterlogging on some roads in the county seat.
According to China Central Television (CCTV) News, from July 25 to 26, Fuping County in Baoding City, Hebei province, experienced heavy rainfall. According to the Fuping County Flood Control and Drought Relief Headquarters, as of 6:00 p.m. on July 26, 46,235 people in six townships had been affected by the rainstorm, with 2 deaths, 2 missing, and 1,289 households (4,655 people) relocated for safety.
The Baoding Meteorological Bureau reported that the extraordinarily heavy rain experienced in Fuping County surpassed the historical daily rainfall record.
Zhang Tao, chief forecaster at the National Meteorological Center, said that during this rainfall event, 19 national meteorological stations in the north broke the historical monthly rainfall record for the same period, and 13 of these even set all-time records. During this round of rain, cumulative precipitation in northern Shaanxi, Inner Mongolia, northern Hebei, and Beijing generally exceeded 100 millimeters, with northern Shijiazhuang, western Baoding, and other areas exceeding 400 millimeters, fully reflecting the extremity of this weather event.
Zhang Tao explained that the causes of this heavy rain in North China are complex and varied. First, abundant moisture transport by the summer monsoon provided the necessary water vapor conditions for rainfall. Meanwhile, on the northwest side of the subtropical high, there was ample heat, conducive to the formation of unstable atmospheric stratification, which in turn triggers strong convective storms. This area is also where westerly weather systems can exert influence; under the impact of cold air from the westerlies, the convergence of warm and cold air masses, together with convection in warmer regions, further intensified the rainfall and expanded its scope. In addition, orographic lifting by mountain ranges such as the Taihang Mountains increased the efficiency of water vapor rising and condensing into rain, and even triggered strong convective cumulonimbus clouds, exacerbating the local extremity of the rainfall.
Zhang Tao suggested that, as this is currently the peak season for summer tourism, travelers should pay close attention to the weather conditions at their destinations and exercise increased caution when traveling to mountainous areas during periods of heavy rainfall.
