Polar Predictability and Dynamics through Multi-scale Atmospheric Vortices
Abstract
Funds are provided to conduct research to expand the knowledge of polar region processes and predictability by evaluating the atmospheric dynamics of tropopause polar vortices (TPVs), and their role in the formation of extreme atmospheric cyclones near the surface and on longer time-scales beyond one week. The proposed research will investigate the core hypothesis that the accurate prediction of TPV intensity is important for predicting the strength of extreme atmospheric cyclones near the surface. Hypothesis testing will apply new knowledge of TPVs to their relationship with the arctic jet stream and expand the conceptual model of the life cycles of extratropical cyclones. This study will apply the following approaches to examine the hypothesis: (1) isolating and identifying important physical processes through controlled, idealized numerical modeling experiments, (2) applying theoretical expectations to diagnose key uncertainties in observed processes and identify specific methods of improving process representation in numerical models.
