| Abstract: | Based on the 1955—2009 daily minimum temperature data,linear trend method and abnormal frost index are used to analyze the interannual and interdecadal anomalies of frost in Shijiazhuang.The results show that averagely the first frost date in Shijiazhuang is November 7,the final frost date is March 21,and the frost-free period is 230 days.The frequency of extremely early first frost is 5%,the frequency of the earlier first frost is 16%,the frequency of very late frost is 4%,and partially late frost is 15%.Most unusual frost in Shijiazhuang occurred during 1950—1980.After 1990,the first frost date was postponed,the final frost date was advanced,and the frost-free period extended.Linear tendency rates of the first frost date,final frost date and frost-free period were 2.85 days,-4.10 days and 6.95 days per 10 years,respectively. |
