Interannual variability of the extratropical northern hemisphere and the potential vorticity wave guide

Abstract Interrannual flow variations in the extratropics are reappraised from a potential vorticity (PV) perspective. A statistical study of the patterns of PV variability on a tropopause‐transecting isentropic surface provides a compact description of, and dynamical insight into, the Pacific‐North...

Description
Summary:Abstract Interrannual flow variations in the extratropics are reappraised from a potential vorticity (PV) perspective. A statistical study of the patterns of PV variability on a tropopause‐transecting isentropic surface provides a compact description of, and dynamical insight into, the Pacific‐North American teleconnection and the North Atlantic Oscillation.
