Session ID#: 17444

Session Description:
How understanding / quantifying the effects of water and energy exchanges in the current and changing climate can be improved and how the uncertainties can be conveyed to society has been identified as key science questions by both the WCRP Global Energy and Water Cycle Exchanges Project  (GEWEX) and the NASA Energy and Water Study (NEWS). New approaches are being developed to investigate water cycle behavior across various spatial scales (e.g., atmospheric rivers and water isotopes). These new methods have the potential to provide new insight into the complex hydrological cycle.  We encourage contributions that utilize these novel techniques in both observations and process modeling. This session will address uncertainty in current data sets, consistency among water and energy budget components, and how these factors relate to our understanding of recent climate variability. Extremes, especially the water and energy cycle dynamics behind those extremes are of particular interest.
