The ASCAT L2B data are provided by EUMETSAT OSI SAF. The CMA best-track data are available at http://tcdata.typhoon.org.cn/ (last accessed on 30 January 2022) The estimation of tropical cyclone (TC) intensity using Ku-band scatterometer data is challenging due to rain perturbation and signal saturation in the radar backscatter measurements. In this paper, an alternative approach to directly taking the maximum scatterometer-derived wind speed is proposed to assess the TC intensity. First, the TC center location is identified based on the unique characteristics of wind stress divergence/curl near the TC core. Then the radial extent of 17-m/s winds (i.e., R17) is calculated using the wind field data from the Haiyang-2B (HY-2B) scatterometer (HSCAT). The feasibility of HSCAT wind radii in determining TC intensity is evaluated using the maximum sustained wind speed (MSW) in the China Meteorological Administration best-track database. It shows that the HSCAT R17 value generally better correlates with the best-track MSW than the HSCAT maximum wind speed, therefore indicating the potential of using the HSCAT data to improve the TC nowcasting capabilities This research was funded by the National Natural Science Foundation of China, grant number 42027805 With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2022-02-25T09:14:56Z 2022-02-25T09:14:56Z 2022-02 artículo http://purl.org/coar/resource_type/c_6501 Remote Sensing 4(4): 1035 (2022) CEX2019-000928-S http://hdl.handle.net/10261/262007 10.3390/rs14041035 2072-4292 http://dx.doi.org/10.13039/501100011033 http://dx.doi.org/10.13039/501100001809 en https://doi.org/10.3390/rs14041035 Sí open Multidisciplinary Digital Publishing Institute |
