They have <br />-- --- ---- <br />--.--~--.- _~---- .-,i> - <br /> <br />! <br /> <br />classified all storms and portions of these storms according to these definitions. . <br /> <br />A summary of their study is included as Table I. <br /> <br />The two storms for which liquid water and other observations are being <br /> <br />reported are storm 9 (8 Feb 83) and storm 14 (28 Feb 83). The flight period for <br /> <br />storm 9 provided a little over two hours of data during an area-wide PET and a <br /> <br />little over one-half hour during a convective PET. The flight of 28 February 1983 <br /> <br />was during a period for which the PET was not classified by North American <br /> <br />Weather Consultants. The PET would likely have had a North American classifi- <br /> <br />cation of N which indicates no echo and no Tushar precipitation. None of the <br /> <br />precipitation gages reported precipitation during this interval. These <br /> <br />analyses thus provide limited but important opportunity to consider cloud <br /> <br />liquid water for area-wide synoptic scale precipitation events with possible <br /> <br />~ <br /> <br />convective elements and an event with no precipitation but with large <br /> <br />convective type clouds. They do not provide information on the important <br /> <br />orographic cloud and mesoscale cloud bands or cases with precipitation <br /> <br />over the Tushars but no precipitation echos. <br /> <br />The three additional storms <br />---- -- ,---- <br /> <br />with airc~a~t da~~ which have n~~-y~t be~~lyzed present opportunities <br /> <br />to broaden the documented base for area-wide and convective PETS (nearly four <br /> <br />hours of A for 25 January, nearly two hours of C and one hour of A for the <br /> <br />28 January storm, and nearly two hours of A and one hour of C for the 13 February <br /> <br />case). When these are completed 1there will be a reasonable case docmnentation <br /> <br />for area-wide precipitation and convective precipitation, but still no <br /> <br />~ <br /> <br />documentation for the North American Weather Consultants' classification of <br /> <br />~ <br /> <br />orographic precipitation, band precipitation, or precipitation with no observed <br /> <br />radar echos., <br />
