摘　　要：2017年春季至夏初,赤道中东太平洋海温将处于中性状态。2017年夏季(6—8月),全国总体降水形势趋于常年,出现大范围洪涝灾害的可能性不大。预计,华南大部、黄淮流域、华北东部、东北南部、东北北部、新疆大部和西藏南部地区降水正常略偏多,其中新疆北部降水偏多2成左右。我国其他大部分地区降水正常略偏少。预计2017年登陆台风数接近正常。The equatorial sea surface temperatures （SSTs） over the central and east-central Pacific are in aneutral state at present and would keep this state through the coming spring and early summer of 2017, according to the real-time prediction result of the ENSO prediction system of Institute of Atmospheric Physics, Chinese Academy of Sciences （lAP, CAS）. According to the seasonal rainfall prediction at IAP, in summer （June to August） of 2017, the overall rainfall situation in China tends to perennial, there is little possibility of a large extent of flooding. A wetter-than-normal condition is predicted for most parts of south China, Huang-Huai basin, eastern part of North China, southern and northern parts of Northeast China, most parts of Xinjiang, and southern part of Tibetan Plateau, whereas the other parts of China will experience a drierthan-normal condition during the boreal summer. In this summer, the number of landing typhoons is predicted to be near normal.
