All mid-latitude cyclones eventually weaken and dissipate. This can happen for a combination of the following reasons: loss of access to warm air, loss of access to moisture, occlusion of cooler/drier air around the low. Generally, the cold front moves faster than the warm front. Thus over ...
Accelerated warming in the Arctic, as compared to the rest of the globe, might have profound impacts on mid-latitude weather. Most studies analyzing Arctic links to mid-latitude weather focused on winter, yet recent summers have seen strong reductions in
