Heavy rain, high temperatures, typhoons ......Since the beginning of the flood season in 2023, China's weather and climate have been complex, the intensity of typhoons has been strong and the impact has been heavy, the northward circulation of "Dusuri" has caused more than 10 provinces to encounter extremely heavy rainfall, and "Kanu" has brought strong wind and rain to the Northeast to cause disaster superposition effects, many rivers in the main and tributaries of the Songhua River basin have exceeded the alert water level, and farmland waterlogging ...... have occurred in many places in Northeast China
In 2023, extreme weather during the flood season will occur frequently, and there will be 35 large-scale rainstorm weather processes in China, of which 20 are strong, 13 are strong, and 2 are extremely strong, which is slightly less than last year, but the intensity of the rainstorm is high and extreme. The national average precipitation is 5323 mm. This year's rainfall is also characterized by extreme characteristics. Since the beginning of the flood season, a total of 72 national stations have exceeded the historical extreme daily precipitation and 346 national stations have exceeded the monthly extreme value, with the maximum cumulative precipitation reaching 3078 mm.
It is extremely necessary to carry out the work of "looking back" during the flood season. Comprehensively summarize the flood prevention problems and hidden dangers exposed under extreme weather and heavy precipitation in the flood season, analyze and judge them in a timely manner, solve various problems in a targeted and accurate manner, and add intelligent flood control monitoring equipment to effectively improve the city's flood control capacity. Only by re-investigating risks and hidden dangers, upgrading flood prevention measures, re-consolidating risk elimination and rectification, and taking careful measures can we ensure the safety of the flood season.
