| Today's discussion concerns itself with manually tracked visible winds located above hurricane Luis (1995). These observations likely are representative of the mean wind conditions in the top 150 mb (three to four km) of the storm and are indicative of the outflow layer of the storm. The wind vectors shown in Fig. 1 are the storm relative composite of six individual hours of winds which have been moved to a center relative location at 18Z on 6 September (20.1 N, 64.9 W). Storm motion (~310/10) has also been removed from the wind vectors. The combination of six hours of winds has resulted in a composite average pattern. In general the outflow is cyclonic and divergent with many clear asymmetries. Points of interest include the relative wake to the right of the center, very strong inner-core outflow to the south of the center, and that circular motion is maintained only in the inner most region. It is hoped that these upper level synoptic hour snap shots can be 1) compared to similar averages from other storms with varying intensities and motions, and 2) combined with Air Force reconnaissance data (10,000 ft) placed in the same synoptic hour relative format yielding a 6 hour semi-three-dimensional look at the inner structure of a hurricane. | |
