| 摘 要： | 利用广州市1951-2006年实测日降水量资料,通过统计方法对使用降水量和无雨日数判别广州季节性干旱情况作对比分析。结果发现,各季降水量和无雨日数序列之间都存在显著的反相变化关系,以冬季最显著、夏季最差;对日雨量较大的季节如春、夏季,用无雨日数判别季节干旱现象要比降水量更合适些,而对其它季节则2种指标无明显差别。 |

| Abstract: | Based on the observed daily rainfall data from 1951 to 2006 in Guangzhou, the seasonal drought events are analyzed comparatively with rainfall amount and the non - rainy days. The results show that there exists significant out - phase correlation between rainfall and non- rainy days in all seasons. The correlation is the most significant in winter and the least in summer. For the seasons such as spring and summer when there are abundant rainfall, the non - rainy days is better to discriminate the seasonal drought events than the rainfall amount, while for other seasons there is no remarkable difference between the results by the two indices. |
