Surface Cyclolysis in the North Pacific Ocean. Part III: Composite Local Energetics of Tropospheric-Deep Cyclone Decay Associated with Rapid Surface Cyclolysis
Two regional local energetics composites of tropospheric-deep cyclone decay were constructed based upon 49 cyclones in the Gulf of Alaska region and 18 cyclones in the Bering Sea region whose decay was marked by rapid surface cyclolysis. Both composites indicate that surface drag is only a secondary...
