New insights into Land–Atmosphere Interactions and Hydrometeorological and Hydroclimatological Extremes (Invited Presentation)

In recent decades, the role of terrestrial-atmosphere interactions on weather and climate processes has become better understood due to key advancements in observational capabilities and analytical tools. However, many questions remain concerning the strength and magnitude of land-atmosphere interactions across varying scales (e.g., local to global), directionality (one-way versus fully coupled), and critical environmental processes. In particular, in a changing climate system in which the hydrological cycle is accelerating, what are the key linkages between surface conditions over terrestrial regions and critical features such as precipitation enhancement, precipitation recycling, (flash) drought development and intensification, and migrating transition zones associated with local features such as urban encroachment versus regional to continental processes such aridity gradients? This study will examine how recent results are addressing such topics as specifically related to hydrometeorological and hydroclimatological extremes across spatial and temporal scales.
