Cross-latitude Teleconnection via Rossby Wave Breaking and Its Impacts on Arctic Variability and Prediction
Abstract
Funds are provided to conduct fundamental research to understand the cross-latitude teleconnection between lower latitudes and the Arctic via Rossby wave breaking (RWB) and the impacts of the teleconnection on Arctic temperature and sea ice variability and prediction. A special focus of the project is the link between RWB and Arctic cyclones/polar lows. Given the prominent role of RWB in the tropical-midlatitude interaction, it is conceivable that RWB also plays an important role in the midlatitude-Arctic interaction. The interaction may affect the large-scale dynamics via the eddy-mean interaction and the large-scale thermodynamics (such as temperature and humidity) via the poleward heat and moisture transport. The PI will investigate the link between RWB and Arctic weather and climate anomalies using observational data, and then will evaluate the representation of the identified links and their implications for extended-range prediction in numerical model simulation. The proposed work is expected to advance our understanding of the fundamental processes that control Arctic cyclone and polar low activity and contribute to improvement in extended-range prediction.
