Abstract
Impacts of Tibetan Plateau (TP) snow anomalies on the Asian Summer Monsoon have been well examined. My talk instead discusses recent progresses on impacts of TP snow anomalies on the Northern Hemisphere (NH) atmospheric circulations in all seasons. Our observational studies and numerical experiments consistently demonstrate that persistent TP snow anomalies can lead to a hemispheric Pacific-North American teleconnection response in winter, a North Pacific Oscillation teleconnection response in spring, and a distinct hemispheric teleconnection pattern in summer which intensifies NH heat waves. Remote atmospheric responses result mainly from the anomalous horizontal propagation of stationary Rossby wave energy and transient eddy feedback mechanisms.
