General information and objectives

To work with other WCRP initiatives to demonstrate skill in predicting changes in water resources and soil moisture on time scales up to seasonal and annual as an integral part of the climate system.




Specialized Research Task:


The GHP will be responsible for assisting GEWEX to demonstrate skill in predicting variabilities in water resources and soil moisture on time scales up to seasonal and annual as an element of WCRP's prediction goals for the climate system.




Premise:


The prediction of regional precipitation and runoff anomalies over periods of several months is a possibility with improved understanding of water cycle processes.



Issues:



  • What is the relative influence of local vs. non-local controls on precipitation over land?
  • How do local controls vary from region-to-region ?
  • What are the feedback mechanisms in the water cycle and to what degree do they affect wet and dry spells?
  • How well can we determine the soil moisture field?
  • What can be done to improve collaboration with water resources agencies on how to better use improved information


Strategy:


Work toward the following scientific milestones with relevance to policy:



  • By the year 2000 quantify evaporation, precipitation and other hydrological processes as required to improve prediction of regional precipitation over periods of one to several months.

  • By the year 2005 predict variabilities in water resources and soil moisture on time scales of seasonal to annual as an element of WCRP's prediction goals for the climate system.




Results:


  • Improve regional flood forecasts and drought

  • Predict climate related anomalies in water resources

  • Improve models of seasonal-to-interannual climate variability





Benefits:


  • water management

  • agriculture

  • power distribution

  • weather prediction

  • transportation

  • environmental assessments
