Abstract: In order to study the precipitation and its characteristics at all seasons of Anqing in nearly 60 years, and predict the precipitation trend of Anqing in short term, to provide scientific basis and guidance for the agricultural production in the area, and guidance for flood control and drought relief. The author used Morlet wavelet to analyze the precipitation data of Anqing city in nearly 60 years. The results showed that: the precipitation concentrated in spring and summer and annual precipitation was increasing slightly. After experiencing 6 cycles, it would enter a new wet season after 2010. The variation trend of precipitation was different in four seasons. It was on a declining curve in spring and autumn, but on the rise in summer and winter. Anqing city’s smaller scale cycle shocked significantly in nearly 60 years, and it had a strong periodicity. The inter-annual rainfall changed greatly and alternate frequently. Floods and drought were easy to appear, but severe drought was hard to appear. In spring and summer, Anqing was influenced by monsoon circulation. Atmospheric circulation changed frequently and inter-annual precipitation varied greatly. Wet and dry alternated frequently. Small scale cycle shocked significantly. The inter-annual rainfall changed greatly and droughts and floods appeared frequently. While it was affected by the westerlies in autumn and winter, north air flow was prevailed. Air was relatively drier than it in spring and summer. Precipitation varied smaller. The inter-annual rainfall changed smaller relatively too. Drought and flood alternated slower than it did in spring and summer. Small scale cycle shocked not significantly.
