Tropical cyclones constitute one of the greatest potential threats to life and property in many eastern and western hemisphere counties. In order to mitigate the considerable human, economic, and environmental impacts of storm events, it is critical that coastal emergency managers, state officials and the general public receive advance and accurate Tropical Cyclone (TC) forecasts and warnings. Since the advent of numerical weather prediction, models have demonstrably improved the forecasts of TC track over the past several decades. While TC motion is largely determined by the large-scale atmospheric environment, changes in storm intensity is a more complicated process that is typically influenced by processes on various scales, including difficult to observe ocean-atmosphere interactions. While the broad factors that control TC intensity change are relatively well understood, accurately assessing the relative roles and non-linear interactions of these multiple processes has proven difficult and has led to the limited reliability of forecasts that predict TC intensity change and structural evolution. In recent years, observations and simulations of TC air-sea interaction and boundary layer processes have been encouraging.
While a specific focus of this workshop will be to further study and investigate these promising advances, the overarching goal is to bring together global TC researchers, forecasters and decision makers to exchange knowledge, skills and propose realistic paths forwards to improve future observations, modelling capabilities and forecasting accuracy within in the Northwest Pacific and Atlantic Ocean basins.
