Why is it important?

This was for the special issue in Atmosphere, entitled “Water Vapor in the Atmosphere”. The study presents a comparison study at three basins in the midlatitudes at different continents to verify the theory that extreme precipitation and floods are highly associated with enhanced moisture transport, which is guided by large scale atmospheric circulation. The three basins present the most flooded region in the North Hemisphere. The results are of great values for future flood risk management in these regions. The study proved that the underlying dynamical drivers interact in the same causal structure for triggering extremes. This offers the foundation for future research pursuit by the entire community to enable reliable prediction of extremes and forecasts of flooding in the temporal and spatial scales that offer the most decision making support.
