RISAn Application of a Weakly Constrained 4DVAR to Satellite Data Assimilation and Heavy Rainfall Simulation
Publisher: American Meteorological Society
Abstract: In this paper a simple weakly constrained four-dimensional variational data assimilation (4DVAR) technique (W4DVAR) is used in the assimilation of retrieved satellite data for a heavy rainfall simulation. The W4DVAR and ...
