[目的] 揭示中国东南沿海地区降水集中度(PCD)和集中期(PCP)时空变化特征
为科学应对旱涝灾害和水资源利用等提供依据。[方法] 基于东南沿海地区46个气象台站的逐日降水量资料
采用Morlet小波分析、EOF等气候分析方法对1960-2013年东南沿海降水集中度和集中期时空变化特征进行分析。[结果] 在时间变化上
PCD波动幅度介于0.10~0.25
存在13~16 a
19~23 a和33~35 a的周期变化;PCP波动幅度介于139.5~208.2
存在13~16 a和25~30 a的周期变化。在空间变化上
PCD具有明显的地域分异特征
PCP空间差异性大。[结论] 1960-2013年中国东南沿海地区降水集中度在增强
且沿海地区值大于内陆地区;降水集中期稳定波动
空间上变化具有一致性。
[Objective] The spatial-temporal variation characteristics of precipitation concentration degree(PCD) and precipitation concentration period(PCP) on the southeast coast of China were studied to provide bases for dealing with drought and flood disasters as well as water resources utilization scientifically. [Methods] Based on daily precipitation data from 46 meteorological stations during 1960-2013 on the southeast coast of China
the authors investigated the characteristics of PCD and PCP using wavelet analysis and Empirical Orthogonal Function(EOF) methods. [Results] Fluctuating range of PCD was between 0.10 and 0.25; PCD had three cycles: 13~16 a
19~23 a and 33~35 a. PCP ranged between 139.5 and 208.2 and it had two cycles: 13~16 a and 25~30 a. An obvious characteristic of PCD was regional differentiation. Spatial variation of PCP was notable. [Conclusion] During 1960-2013 in the southeast coast area of China
PCD increased
and the values of PCD of coastal areas were higher than those of inland areas. PCP fluctuated steadily.
