Characteristics and Predictability of Arctic Cyclones
Abstract
Funds are provided to conduct research to understand the structure, dynamics, and predictability of major Arctic cyclones that are thought to play a major role in the evolution of the Arctic sea ice cover. Two aspects are proposed to address these issues. First, the development, evolution, and decay along with the attendant dynamics of strong Arctic cyclones and intense polar lows will investigated using newly available state-of-the-art reanalyses that have high horizontal and vertical resolution and are expected to resolve these events much more accurately than previously. Second, forecasting experiments on intense (and representative) Arctic cyclones and polar lows will be conducted to determine how well these events can be predicted for a few days into the future. Simulations will feature high horizontal and vertical resolution, realistic but specified ocean and sea ice conditions, and advanced assimilation of a wide array of observations to provide accurate and detailed initial conditions for the model forecasts. This work will be performed in close cooperation with the Mesoscale Modeling Section of the Marine Meteorology Division at the Naval Research Laboratory. The goal is to improve understanding of processes that will advance the physics and predictive skill of the Navy???s Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS).
