摘要
According to one embodiment, there is provided a climate analysis apparatus for diagnosing Madden-Julian oscillation (MJO) simulation performance of a climate prediction model, comprising: an acquisition unit configured to acquire weather information; a processing unit for diagnosing simulation performance of the climate prediction model based on the weather information; And an output unit for outputting the simulation performance, wherein the processing unit, through the acquisition unit, the weather prediction information and climate observation equipment predicted by the climate prediction model in a first region in a first period in the first region Obtaining the weather observation information observed in the first period, on the basis of the MJO index, obtaining the predicted MJO information corresponding to the predetermined phase from the weather forecast information, and on the basis of the MJO index, from the weather observation information Obtaining the observed MJO information corresponding to a predetermined phase, and analyzing the MJO information including the observed MJO information and the predicted MJO information and/or at least one or more determination indicators derived from the MJO information according to a comparison criterion to analyze the climate Diagnose the simulation performance of the prediction model, but the MJO information includes weather information corresponding to Outgoing Longwave Radiation (OLR), upper wind field (U200) and lower wind field (U850), and the MJO index is in the MJO information. It is obtained according to an EOF (Empirical Orthogonal Function) analysis method based on the included weather information.
