Understanding and predictions of sub-seasonal to seasonal (S2S) land-induced forcing and atmosphere interactions on droughts/floods and heatwaves
Session ID#: 75836
Session Description:
Despite the substantial progress that has been achieved in recent decades, the prediction skill for heat and precipitation anomalies in spring and summer months has remained stubbornly low, which underscores the need to seek explanations beyond the sea surface temperature influence alone. This session welcomes contributions on improving understanding of sub-seasonal to seasonal (S2S) variability and prediction of heatwaves and precipitation, especially droughts and floods, through land-induced forcing/atmosphere interactions. Topics include local and remote effects of land surface/subsurface temperature, snow, snow darkening by light-absorbing particles in snow, vegetation, and soil moisture on S2S prediction, as well as mechanisms of dynamic and physical processes and hydroclimate feedback. Results from global and regional model based-studies and model intercomparison projects, such as the GEWEX/GASS/Impact of initialized land temperature and snowpack on sub-seasonal to seasonal prediction (LS4P), observational validation/analyses with satellite, site measurements (especially for snow cover), and reanalyses are encouraged.
