The Role of Land Surface Feedbacks in Drought Monitoring and Forecasting

Abstract:  

Drought, a hydrometeorological extreme, causes substantial socio-economic losses globally. Mitigation of the losses can be facilitated by a proactive approach based on real-time drought monitoring and forecasting systems.  This seminar will focus on two ongoing efforts to provide real-time drought monitoring and forecasting (i) over CONUS as part of the North American Land Data Assimilation System (NLDAS) and (ii) over Africa and the Middle East and Central Asia through USAID’s Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System (FLDAS).  Primary focus will be on (i) the role of groundwater and dynamic vegetation in representing the feedbacks during drought periods over CONUS (ii) the role of precipitation quality and the ability of FLDAS to simulate water availability during long term (hydrological) droughts over Africa.
