A Challenge of the Experiment on Typhoon Intensity Change in Coastal Area

Abstract

ABSTRACT: The Experiment on Typhoon Intensity Change in Coastal Area (EXOTICCA) was proposed by the China Meteorological Administration (CMA) and Hong Kong Observatory (HKO) and endorsed by the ESCAP/WMO Typhoon Committee (TC). The major goals and objectives of the EXOTICCA are: 1) to conduct the field campaigns on the intensity and structural characteristics of the target offshore and landfall tropical cyclones by employing integrated and novel observation techniques, and 2) to conduct demonstration research on the utilization of the synergized field observation data with the aim of deepening the understanding of the mechanism of structure and intensity changes, to improve the relevant capability of operational analysis, numerical weather prediction (NWP) models forecast, reliable storm surge and flooding and associated risk assessment. The Organizational structure and implementation schedule etc. are also introduced in this paper. Keywords: tropical cyclone, intensity, experiment, field campaign, numerical weather prediction (NWP)
