| Abstract: | Using daily meteorological data from eight national observation stations in Shaoguan from 1965 to 2020,this work performs a statistical analysis of the characteristics of air temperature,precipitation and sunshine duration during the Spring Festival travel rushes as well as the climatological characteristics of such destructive weather as chilly temperature,hard rain and fog that are adversary to them.The results are shown as follows.For the 56 years studied,the average air temperature for the Spring Festival travel rushes of Shaoguan tends to increase but the precipitation tends to decrease,both insignificantly though.The variation of sunshine duration is not significant.Chilly temperatures take place frequently in Nanxiong county,with extreme minimum temperatures appearing in Renhua and Shixing counties.The number of hard rain days tends to rise with the maximum in Ruyuan county.Annual fog probability is as high as 95%and shows an insignificantly rising trend. |
