Advanced Satellite-Derived Wind Observations, Assimilation, and Targeting Strategies During TCS-08 for Developing Improved Operational Analysis and Prediction of Western Pacific Tropical Cyclones
Abstract
Forecasts of tropical cyclone (TC) formation and intensity change in the north-western Pacific basin are often lacking in skill, in part due to the paucity of conventional oceanic observations that are assimilated into the operational models. This lack of observations has also constrained our understanding of how TC formation is governed by environmental processes. Recently, remotely-sensed observations from satellites have become a routine and important input to the global data assimilation systems. To our knowledge, this project represents the first time anyone has tried to evaluate the impact of targeted satellite data on TC forecasts using an automated dynamic targeted observing strategy. TCS-08 will afford us the opportunity to employ specially-processed satellite data along with observations collected in situ by the NAVY P-3, and other platforms, to investigate these objectives as they apply in the western north Pacific TC basin. The development of successful real-time strategies to optimally assimilate wind data from satellites will ultimately lead to the provision of improved initial and boundary conditions for the Navy's envisioned mesoscale coupled ocean-wave-atmosphere forecast model.
