| Abstract: | Using the hail and monthly average temperature observation data at 142 stations in Hebei Province and NCEP reanalysis data from 1961 to 2007,the spatial and temporal distribution characteristics of hail and variation rule with time and circulation features of more and less hail years are analyzed by the statistical analysis methods of Mann-Kendall test,wavelet analysis,and correlation analysis.The results show that day numbers of hail have obvious interannual variation,an abrupt change of day number of hail... |
