Strategies for coupling global and limited-area ensemble Kalman filter assimilation

This paper compares the forecast performance of four strategies for coupling global and limited area data assimilation: three strategies propagate information from the global to the limited area process, while the fourth strategy feeds back information from the limited area to the global process. Al...
