| Abstract: | Based on the data of temperature and precipitation from 1951 to 1995 in North of China, indices for the first soaking rain in spring and its distribution, mainly depended on precipitation and temperature, were determined in Northeastern China, Northern China and the eastern parts of Northwestern China. The characteristics and probabilities of the first soaking rain in spring at each region were discussed and analyzed. It showed that the results would provide good instructions for monitoring and predicting to occurring of the spring drought. |
