(1999), have been launched in several tropical cyclones (TCs) from aircraft by the Hurricane Research Division (HRD) of NOAA since 1996. During TC landfall missions conducted by HRD, some of these GPS-sondes were intentionally dropped in the vicinity of National Data Buoy Center (NDBC) platforms that have reliable and very accurate measurements of surface atmospheric conditions. These data include air temperature, surface pressure and wind speed and direction. In addition, many of these NDBC platforms recorded surface oceanic parameters, such as sea surface temperature and ocean wave and swell characteristics. The NDBC platforms have historically performed very well under the extreme conditions that occur in severe oceanic storms, including TCs. The NDBC observations of atm ospher ic condit ions were available for comparison with high-resolution vertical profiles of winds, temperature and pressure that were made by the GPS-sondes dropped nearby. The previous study by Houston et al. (2000) that provided comparisons between GPS-sondes and NDBC platforms using 1998-99 TCs was based on only 26 cases. Despite this rather sm all sam ple number, the comparisons of GPS-sonde near surface temperatures and pressures were very close (within 1 OC and 1 mb, respectively) with a re latively sm all variance. However, the wind speed measurem ents showed a great deal of variability. This paper will present an update of new statistics using the additional GPS-sonde measurem ents that have been m ade in TCs near NDBC platforms during the 2000-03 Atlantic hurricane seasons. In addition, several "GPS-sondes of opportunity " were launched by the U.S. Air Force Reserves reconnaissance aircraft in the vicinity of NDBC platforms. These cases were a lso added to the |
