[ACG36-P02] GPMデータを活用した閉塞過程を伴う冬季低気圧の３次元構造解析
キーワード：GPM、温帯低気圧、冬季降水
Stagnant wide-range heavy precipitation areas associated with winter extra-tropical cyclones were identified by AMeDAS and GSMaP precipitation data. A case study by GPM/DPR data showed a split front type system with a clear precipitation phase (rain/snow) boundary in the occlusion process over central mountain ranges. Further examinations of meso-scale systems embedded in the organized cyclone are expected by accumulating GPM/DPR products.
