Observed radar and environmental properties of United States warm season bowing convective systems, 2003-2004
MetadataShow full item record
This study examines radar-indicated structures and environments of bowing convective systems in the United States during the warm seasons of 2003 and 2004 (April-December). The bowing process is defined as local acceleration of a convective cell or cells on the convex leading edge of a convective system to form an "arch" or "bow"-shaped line. This study perused data for each day of the two-year time period and investigated the bowing process using 2-km national radar reflectivity composite data. This procedure yielded 381 bowing convective systems, the majority of which occurred from May to July. ...
