Abstract
This study investigates the hazard of East Asian Atmospheric Rivers (ARs) by applying the AR scale to AR catalog. When AR scale is categorized into five ranks from Category 1 (Cat1) to Category 5 (Cat5) by considering the duration and intensity of each AR event, with Cat5 having the most hazardous hydrological impact, Cat5 ARs are most frequently found in East Asian summer, along the northwestern boundary of the western North Pacific subtropical high. More frequent Cat5 ARs than Cat1 to Cat4 ARs are robustly found in eastern China, Korea, and western Japan, due to the slowly-varying monsoonal flow during the East Asian summer monsoon, which transports a large amount of moisture to the region. Since Cat5 ARs often lead to large event-total rainfall, it explains a close relationship of East Asian summer ARs to heavy rainfall events. This finding helps to better understand the potential hydrological impacts of ARs in East Asia.
本研究通过将 AR 尺度应用于 AR 目录，对东亚大气河流 (AR) 的危害进行了研究。根据每一次 AR 事件的持续时间和强度，将 AR 尺度分为从 1 类（Cat1）到 5 类（Cat5）的五个等级，其中 Cat5 对水文的影响最为严重。由于东亚夏季季风期间的季风气流变化缓慢，为该地区输送了大量水汽，因此在中国东部、韩国和日本西部，Cat5 AR 的发生频率高于 Cat1 至 Cat4 AR。由于 Cat5 季风常常导致大的事件总降雨量，这解释了东亚夏季季风与强降雨事件之间的密切关系。这一发现有助于更好地理解东亚夏季季候风对水文的潜在影响。
