摘要： To determine a gas status (wind direction, wind speed), which is detailed in terms of space and time, from meteorological observation data, such as meteorological GPV, which are rough in terms of space and time, initial conditions and boundary conditions set based on the meteorological observation data are incorporated into differential equations for analysis of atmospheric phenomena, and computations are performed by a parallel computer 11. For the computations, a computation period is divided, for example, into four parts. Computations for the respective divisional computation periods are allocated to four processing units CPU's #1˜#4 and performed simultaneously and parallelly. The results of the computations by the processing units CPU's #1˜#4 are combined, whereby the gas status (wind direction, wind speed) detailed in terms of space and time during the entire computation period can be determined. In this case, the period is divided and parallel computations are performed, so that the computation period is shortened according to divisions.
