Characteristics of quasi‐stationary band‐shaped precipitation systems in Japan between 1989 and 2022

Abstract Quasi‐stationary band‐shaped precipitation systems (QBPSs) are the major cause of localized heavy‐rainfall events (HREs) in Japan. Using hourly radar/raingauge‐analysed precipitation amounts from 1989 to 2022, we statistically examined the occurrence characteristics of Q...

Environments of quasi-stationary linear precipitation system associated with Baiu frontal depressions

Abstract Heavy rainfall in Japan is often caused by quasi-stationary linear precipitation systems (QSLPSs), which frequently occur in association with Baiu frontal depressions (BFDs). While the importance of the roles of BFDs in QSLPS occurrence has been suggested by previous cas...

Characteristics of Quasi-stationary Band-shaped Precipitation in the Tohoku Region Detected under Varying Rainfall Thresholds

Abstract Quasi-stationary band-shaped precipitation systems sometimes cause severe rainfall disasters in the Tohoku region of northeastern Japan, but the uniform rainfall thresholds used in existing objective detection methods may be too high for this region. This study examines...
