Abstract. Heavy rainfall events causing floods and flash are examined in the context of solar wind coupling to magnetosphere–ionosphere–atmosphere system. The superposed epoch (SPE) analyses variables have shown tendency severe weather follow arrivals high-speed streams from coronal holes. Precipitation data sets based on rain gauge satellite sensor measurements used examine relationship betwee...

Flash floods are devastating natural disasters worldwide. Understanding their spatiotemporal distributions and driving factors is essential for identifying high risk areas predicting hydrological conditions. In this study, several methods were used to analyze the changing patterns of flash in Altay region. Results indicate that number each year increased 1980–2015, with two sudden change points...
