• The time scale of tropical cyclone track and intensity changes is on the order of 12 hours, which makes JPSS instruments well suited for the forecasting of tropical cyclone tracks and intensities. During the annual report period, we began with the development of two tropical cyclone applications of JPSS data. The first uses the imager and sounder data for improving the center location of tropical cyclones, which is the starting point for tropical cyclone forecasts. We began working on methods to use multi-spectral imagery from VIIRS, including the low-light imager, in combination with sounder data for this purpose. The second is to use temperature and moisture retrievals from ATMS and CrIS in the near storm environment to improve intensity forecasting. The objective is to incorporate this new information into an existing operational statistical-dynamical intensity forecast model to improve its performance. Once completed, these new products will be made available in the Satellite Proving Ground to operational forecasters at the National Hurricane Center (NHC) and Joint Typhoon Warning Center (JTWC) for evaluation and feedback. If the evaluation is positive, or points toward issues that can be adequately addressed via operational/developer interactions, the products can be transitioned to NHC and JTWC operations.
