HAMSR has achieved two particularly notable results during the campaigns it has participated in. As described in Brown, et al, HAMSR has been able to view the warm core structure of a hurricane, as well as its precipitation structure. This is especially important, because it could help to increase our understanding of how hurricanes form and how intense an individual storm might become. Also available is a summary of HAMSR science goals and timelines (PDF, 8.62 MB).
Warm Core Structure
During CAMEX-4 and TCSP, HAMSR was mounted on the ER-2 aircraft and was able to observe Hurricanes Emily (7/25/2005) and Erin (9/10/2001). The magnitude of the warm anomaly in the eye of the storm has been shown to be an indicator of hurricane intensity. The maximum magnitude of the warm anomaly is similar for both hurricanes, peaking at 11-12° C. The warmest temperatures for Hurricane Erin are at 400-600 mb, whereas for Hurricane Emily, they are between 150-250 mb.
HAMSR can measure brightness temperatures to derive the convective intensity of the storm. The precipitation structure of Hurricane Emily was measured on 7/17/2005 by differencing the channels in the 60 and 118 GHz range. This gives an indication of both the height and intensity of the storm. For Hurricane Emily, this method gives an indication of ice content above 10 km.
