SYSTEM FOR MODIFYING MARINE FORECAST DATA

摘要

PROBLEM TO BE SOLVED: To integrally modify the distribution of marine data while maintaining the time and space continuity of a numerical oceanographic model in the forecast results of the numerical oceanographic model.;SOLUTION: A numerical forecast part 1 forecasts time and space data on marine environment such as water temperature, salinity, and current velocity on the basis of the numerical oceanographic model and outputs forecast lattice data 5 and 8. A numerical modification part 2 displays the marine environments forecasted by the forecast lattice data 5 from the numerical forecast part 1, modifies any time and space data on the marine environment, and outputs modified data 6. An optimum interpolation part 3 interpolates marine environment data manually modified by the modified data 6 from the numerical modification part 2 in such a way that estimation error at each computation lattice point may become minimum and outputs it as modification lattice data 7. A data assimilation part 4 integrates the modification lattice data 7 modified at the numerical modification part 2 and interpolated by the optimum interpolation part 3 with the forecast lattice data 8 from a numerical forecast part 1 through the use of a data assimilation technique and outputs it as assimilation data 9.;COPYRIGHT: (C)2004,JPO
