Meteorological field objective analysis device and meteorological field objective analysis method

摘要

PROBLEM TO BE SOLVED: To provide an objective analysis device of a meteorological field and an objective analysis method of a meteorological field, which can perform an objective analysis of a meteorological field with high resolution, high frequency, and high accuracy in real time.SOLUTION: An objective analysis device 10 of a meteorological field includes: an observation data acquisition part 11 for acquiring observation data of a meteorological field; an initial value creation part 12 for creating an initial value at an initial time; a forecast value creation part 13 for continuously creating a forecast value of the meteorological field from the initial value in each prescribed time; a restart file creation part 14 for creating a restart file including information for creating a restart forecast value and subsequent data; an estimate creation part 15 for creating a forecast value of an analysis time when new observation data is inputted, as an estimate; a temporary analysis part 16 for calculating an analysis increment from the new observation data acquired by the observation data acquisition part 11 and the estimate created by the estimate creation part 13; and an actual analysis part 17 for outputting an actual analysis value.SELECTED DRAWING: Figure 1
