Tornadoes and downbursts are the most violent winds in all of them though their scales are relatively small. It is difficult for ordinary meteorological observation systems, e.g., Doppler radar and so on, to catch these hazard winds in detail. Then, we need experimental simulations of these hazard winds to clear their structure and generation mechanism of them. Some recent results of our experiments on tornadoes and downbursts are shown in the present paper., 形態: カラー図版あり, 資料番号: AA0064237020, レポート番号: JAXA-SP-08-006}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {大気の組織構造: 竜巻とダウンバースト}, volume = {JAXA-SP-08-006}, year = {2009} }
