| Abstract: | Climatological characteristics about temporal and spatial variations of anomalies of 31 stations' soil temperature at depth 1.6m in China from 1974 to 1976 have been analysed. The results show that there is strong persistence in anomaly field of soil temperature. The more range of soil temperature anomaly changes large, the more the anomaly persists long. Meanwhile, it has been found that there is obvious quasi-semiannual rhythm in the seasonal transition of the anomaly field of soil temperature from winter to summer. Otherwise, accumulative absolute value of the anomalies of month's soil temperature in winter-half-year is large (or small), then the rainfall variability is high (or low) next year (and its flood season). |
