Study on Gale Distribution Characteristics and Risk Regionalization in Jiamusi Area
The regular meteorological data from 2017 to 2021 are used to analyze the spatiotemporal variation characteristics and early warning characteristics of gales in Jiamusi region,according to the natural disaster risk theory,the gale disaster risk assessment index system in Jiamusi area is constructed to carry out the gale risk zoning.The research shows that the annual average number of gale days in Jiamusi area is 15.6 days,and Huanan County has the most,reaching 36.8 days;strong winds mostly occur in spring and autumn,with peaks from March to May and September to November respectively;the number of maximum wind speed exceeding the blue warning threshold is much more than the average wind speed exceeding the threshold.When the average wind speed reaches the warning standard,the maximum wind speed will also reach the warning standard;Huanan County has the highest risk;The high-sensitivity area of the disaster-pregnant environment is located in the southern part of the Jiamusi region.Due to factors such as population and economy,Fujin City has the highest vulnerability risk of disaster-bearing bodies.
