An observational and numerical investigation of energy exchange between a tropical cyclone and its environment at the outflow level
Abstract
This proposal follows on the successful TCI field studies accomplished in 2014-2015, that obtained unprecedented high-resolution (1.""5 km) dropsonde observations of hurricanes Patricia, Joaquin and Marty. This project will enable the PI~s up to 7 journal papers ba""sed on TCI observations and supporting model simulations and begin extending their research toward developing a new hypothesis, insp""ired from observations of hurricanes Patricia and Matthew, combined with the surprising the skill of long range global forecasts of"" these events. The hypothesis is that TC genesis may be responding to direct dynamic forcing from extra-storm-scale disturbances, pi""cked up by the global models, and communicated to the storm scale by outflow level divergence forcing. This research will be pursued"" by further investigating evidence collected from TCI, that deep convective activity spawned outside the eye wall, is tied to the re"lease of gravity waves trapped by the diurnal varying stability of the mid-upper troposphere in the outflow layer.
