Abstract: Based on observations in China during last 30 year s(1954-1983) it was found that seasonal anomalous patterns of soil temperature at a depth of 80cm look similar to the pattens of precipitation of the subsequent season. The mean distance of the maximum axes between the above two elements were less than 2 Lat. with a percent of 76 00.To predict the subsequent season will be a wet(dry) season at east half China, a clear signal is that a cold trough(warm ridge) of 80cm soil temperature have been located in the east edge of Tibet Plateau (100°-105°E) during this season.
