The AER Arctic Oscillation blog, led by Dr. Judah Cohen, represents our daily research, review, and analysis of the Arctic Oscillation (AO) and Polar Vortex (PV). This analysis is intended to provide researchers and practitioners real-time insights on one of North America’s and Europe’s leading drivers for extreme and persistent temperature patterns.
This subscription will provide the following daily depictions of the vertical component of the wave activity flux (WAFz) and the polar cap height (PCH) as a 45-day timeseries (back 30 days, forward 15 days) using the NCEP GFS and GEFS.
