Initialization of Tropical Cyclone Structure for Operational Application
The long-term goal of this project is to improve the prediction of tropical cyclone (TC) genesis, structure and intensity changes through improved representation of 3-dimensional TC structure at the initial time. The accurate prediction of TC genesis, structure and intensity changes is critical to Navy missions and civilian activities in coastal areas. Significant gains have been made in the TC...
متن کاملSystematic Approach to Tropical Cyclone Track Forecasting
The long-term goals of this project, which is being pursued in collaboration with R. L. Elsberry and M. A. Boothe, are to improve not only the quantitative accuracy of official tropical cyclone (TC) track forecasts, but also the qualitative meteorological utility of those forecasts. Needed improvements in the accuracy of official TC track forecasts include: (i) reducing the severity and frequen...
متن کاملTropical cyclone track forecasting techniques: A review
Delivering accurate cyclone forecasts in time is of key importance when it comes to saving human lives and reducing economic loss. Difficulties arise because the geographical and climatological characteristics of the various cyclone formation basins are not similar, which entails that a single forecasting technique cannot yield reliable performance in all ocean basins. For this reason, global f...
متن کاملIdealized tropical cyclone simulations of intermediate complexity: A test case for AGCMs
[1] The paper introduces a moist, deterministic test case of intermediate complexity for Atmospheric General Circulation Models (AGCMs). We suggest pairing an AGCM dynamical core with simple physical parameterizations to test the evolution of a single, idealized, initially weak vortex into a tropical cyclone. The initial conditions are based on an initial vortex seed that is in gradient-wind an...
متن کاملEvaluating the Impact of the GCM Dynamical Core in Idealized Tropical Cyclone Simulations
Using General Circulation Models (GCMs) for tropical cyclone studies is difficult due to the relatively small size of the storms, the intense convection and multitudes of large-scale small-scale interactions. These are mostly unresolved at typical GCM resolutions of about 50-100 km, and still challenged at high resolutions between 12-30 km. Nevertheless, high-resolution GCMs are becoming a tool...
