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...

Impact-based forecasting in Japan: a review of the Japan meteorological agency’s real-time risk map “Kikikuru”

Abstract Impact‑Based Forecasting (IBF) has attracted international attention as an approach to enhance disaster risk management by linking weather forecast information to concrete societal actions. This review examines the implementation of IBF in Japan, focusing on the Real‑tim...

Impact of a Stratocumulus Scheme on Clouds and Feedbacks in MIROC7

Abstract Marine stratocumulus (Sc) clouds exert a strong cooling effect on climate by reflecting solar radiation, yet many climate models underestimate their amount and cause uncertainty in equilibrium climate sensitivity (ECS). Herein, we show that incorporating a physically bas...
