Outline of Final Research Achievements

The present study constructed a data assimilation system which produced realistic initial fields of environmental variables and meso convective systems from satellite microwave imager (MWI) brightness temperatures (TBs). For this purpose, we developed ensemble-based assimilation methods to incorporate MWI TBs into cloud-resolving models (CRMs). The main development items were 1) a sampling error reduction method for precipitation-related variables; 2) a displacement error correction method for precipitation areas.
Then, the present study employed this assimilation system to incorporate MWI TBs for the case of T1306. The results showed that the humid environment around the easterly wave disturbance was most important for the genesis of the tropical cyclone in this case.

Academic Significance and Societal Importance of the Research Achievements

台風発生過程に関しては、様々な仮説が提案されている。これらが現実的な台風の発生に対してどれくらい寄与しているかを考える上では、現実大気に出来るだけ近い、環境場(気温・水蒸気等)と降水を与えたCRMのシミュレーションが不可欠である。本研究の特徴は、衛星搭載マイクロ波放射計などのリモートセンシングデータを精巧な雲物理過程スキームを持つCRMに同化することで、現実的な環境場と降水分布の初期値を得ることである。発生期の台風の通常の観測は非常に少ないが、このリモートセンシングデータを使うと、すべての海域、季節において、台風となっていく渦の組織化がどのように進行していくのかを調べることができる。
