摘要

Atmospheric Rivers (ARs) are narrow and elongated water vapor belts in troposphere with meridional transport across the mid-latitudes towards high-latitudes. Compared with ARs occurred over the northeastern Pacific, the western coast of North America and Europe, the ARs over the East Asia have received less attention. In this paper, the characteristics of ARs which af-fected China in the area 20?–60?N, 95?–165?E in the middle summer season from 2001 to 2016 were investigated by using Euro-pean Center for Medium-Range Weather Forecasts (ECMWF) ERA-Interim reanalysis data and Multi-functional Transport Satel-lites-1R (MTSAT-1R) infrared data. Totally, 134 ARs occurred during that period, and averagely 8.4 ARs occurred per year. Statis-tically, 101 ARs were in east-west orientation, and 33 ARs were in north-south orientation, which accounts for about 75％ and 25％, respectively. Herein we report the occurrence number, duration time, intensity, length, width, ratio of length to width, and exten-sion orientation of these ARs, which provide the basic information for those who have interest in ARs over the East Asia.
