During the 2016 tropical cyclone campaign, several storms ranging in strength from tropical storms to Category 4 were observed over the period of several hours. The most significant storm observed was Hurricane Matthew. The Global Hawk made three consecutive flights over the storm as it transitioned from a tropical to extra-tropical cyclone. During the second flight, Matthew had sustained Category 4 status but was weakening. The HAMSR observations show the evolution of the warm core structure over 10 hours as it was weakening.
In this paper we will highlight the observations of the TC structure and evolution derived from the HAMSR thermodynamic measurements for the 7 flights over 4 named storms. We will show an inter-comparison of the HAMSR vertical temperature and moisture profiles with the co-incidence dropsonde measurements and will discuss the down-scaled product that was developed for data assimilation. Finally, we will discuss the real-time data products that are available during the flight in the context of real-time diagnosis of storm intensity, center position and environmental conditions.
