Atmospheric and hydrospheric phenomena have a variety of spatio-temporal scales from microscales, regional-scales, to global scales. Such phenomena include tornadoes, heavy rainfalls, typhoons, and planetary-scale anomalous weather. Deep and coherent understanding of the mechanisms of these phenomena and also the processes leading to various consequences thereof are the key to mitigate disaster risks. Our thematic area contributes to global disaster risk reduction by providing united efforts in weather and climate related sciences and engineering.
