Application of Microwave Space-Based Environmental Monitoring (SBEM) Data for Operational Tropical Cyclone Intensity Estimation at the Joint Typhoon Warning Center

Abstract The Joint Typhoon Warning Center (JTWC) utilized new space-based environmental monitoring (SBEM) data alongside traditional to adjust JTWC tropical cyclone (TC) intensity and structure estimates during production of the official 2019 Best Track dataset. Intensity from multiple platforms such as Advanced Microwave Scanning Radiometer-2 (AMSR2), Soil Moisture Active Passive (SMAP) Ocean Salinity (SMOS) radiometers, synthetic aperture radar (SAR), along with objective Dvorak satellite consensus algorithms, not only aided poststorm best track (BT) process, but also provided robust that supported real-time analysis forecasting. This summary attempts communicate TC community extent which these affected BT data, how in provide examples influenced forecaster decision-making real time. paper makes no attempt validate accuracy wind speed methods (SAR, SMAP/SMOS, or AMSR2) does outline entirety process for determining intensity, it outline, briefly, impact datasets on final analysis. These methodologies are valuable sources an otherwise data-sparse area responsibility, many cases critical captured by alone, detailed further this summary.
