Monitoring tropical cyclone evolution with NOAA satellites microwave observations

Abstract

<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"> An attempt has been made in this paper to demonstrate the potential use of observations from Advanced Microwave Sounding Unit (AMSU) onboard NOAA 15, 16, 17 and 18 satellites series for the monitoring of tropical cyclones. Geophysical parameters derived from AMSU measurements like surface pressure, upper tropospheric warm core, gradient winds and cloud liquid water are demonstrated for the monitoring of the intensity of recently formed tropical cyclone in the Bay of Bengal on 28 Nov. 2005. The AMSU soundings, which penetrate high clouds, delineate the development and dissipation of the upper tropospheric warm core associated with a tropical cyclone. Vertical cross-sections reveal the intensification of the upper tropospheric warm core as the storm develops, and the downward propagation of the warm core as the storm dissipates. </smarttagtype>
