Airborne measurements of a polar low over the Norwegian Sea

Airborne measurements of a polar low over the Norwegian Sea

We will report an airborne measurement of a polar low over the Norwegian Sea on 9 March 1998 during the Arctic Airborne Measurement Program 1998 (AAMP 98). Global objective analysis suggests that the low formed due to an interaction between an upper level potential vorticity anomaly and a low-level...
