Abstract Torrential Meiyu-Baiu rainfall events have become more frequent in East Asia this
decade. The moisture source and isotopic composition of precipitation are crucial for …

Mesoscale convective systems (MCSs) that occur in the Baiu frontal zone (BFZ) can cause
devastating flash floods during early summer in Japan; however, the environmental …

Persistent and organized convective cloud systems that arise in convergence zones can
lead to the formation of synoptic cloud bands extending from the tropics to the extratropics …

The motivation of our study is to provide forecasters and users complementary guidance and
tools to identify and predict atmospheric conditions that could lead to life-threatening flash …

The precipitation system and environment that caused the heavy rainfall event in July 2020
over Kyushu Island, Japan, were analyzed, with a focus on a hierarchical structure. The …

Abstract In 2020, the Yangtze–Huai river valley (YHRV) experienced the highest record‐
breaking Meiyu season since 1961, which was mainly characterized by the longest duration …

Our recent study suggested that moisture from the subtropical Western Pacific (WP)
contributed the most to an atmospheric river (AR) event and the related heavy rainfall during …

We conducted an observational survey using a ground-based water vapor Raman lidar (RL)
during the warm season in Japan to investigate the water vapor structure of low-level inflows …

As a complement work to the authors' previous studies, we examined the pre-typhoon
rainfalls (PRE) ahead of typhoon T0918 (Melor) in October 2009. The influence of …

Using mesoscale gridded analysis data and radar/raingauge-analyzed precipitation 12
products, this study investigated the environmental conditions for the occurrence of 13 …
