Title: Regional Characteristics of Summer Precipitation over the Mid-Lower Reaches of Yangtze River during Last 45 Years
Abstract: The spatial and temporal features of summer(June—August) precipitation over the mid-lower reaches of the Yangtze River are studied by using the precipitation data of 78 stations from 1960 to 2004.Five climatic subareas of summer precipitation in the mid-lower reaches of the Yangtze River are divided by using Rotated Empirical Orthogonal Function(REOF) method.Mann-Kendall test shows that only Quzhou and Nantong have abrupt change of precipitation at different times.As for long-term variation,summer precipitation in all subareas shows an increasing trend with a strongly increasing trend in Ⅰ and Ⅴ subareas,an obviously increasing trend in Ⅲ subarea,a weak increasing trend in Ⅱand Ⅳ subareas.The oscillation periods of summer precipitation for 5 subareas are also not consistent in the recent 45 years.
