利用“中国历史气候资料检索系统”，发现了近1000年来的15次大旱。干旱范围广，超过4个省，持续时间长达3年以上，其严重程度相当于或超过中国20世纪30年代的干旱，根据文献记载和资料分析，大多数干旱比近50年的干旱严重。这15次干旱可能发生在温暖或寒冷的气候背景下，其中11次处于寒冷阶段。这表明了中国与北方美洲气候对应的差异，表明了中国的气候状况是寒冷而不是温暖的。这可能与东亚的季风气候有关。
The total 15 severe droughts are discovered with the aid of the 'Retrieval System of Chinese Historical Climate Records' for the last 1000 years. The droughts are extensive to envelope more than 4 provinces and persistent to cover 3 yr or more, and their severity is equivalent to or in excess of that in the 1930s in China.According to the documentary records and restorations it can be inferred that most droughts are more severe than those in the last 50 years. The 15 droughts may either occur warm or in a cold climate background,with 11 of the 15 cases in the cold phase. This indicates the difference in climate correspondence between China and northern America, showing the severity of the events in China to be in a cold instead of a warm climate situation. That is likely to relate to the monsoon climate in eastern Asia.
