Properties of Convective Clouds over the Western Pacific and Their Relationship to the Environment of Tropical Cyclones (No-Cost Extension).

摘要

Using data obtained from the western Pacific region during Tropical Cyclone Structure 2008 (TCS-08), ONR's field program, this study proposes to investigate large-scale environmental conditions, mesoscale phenomena, and small-scale convective bursts, as well as their interactions that are responsible for TC formation and intensity changes. Specific objectives include: (1) characterizing the intensity of convection over the western Pacific using radar, aircraft, and satellite data; (2) deriving an accurate mesoscale environment of convective systems through the assimilation of satellite, radar, lidar, and in-situ data; (3) evaluating the quality of the global forecast system (e.g., Navy Operational Global Atmospheric Prediction System, or NOGAPS) for accurate TC analyses and forecasts; and (4) understanding the environmental factors that determine tropical cyclone formation and rapid intensification.
