Cold air surge at the surface: 2 November 2011
From CSU-CHILL
Overview
Positive (outbound) radial velocities of ~15 mps are associated with enhanced northerly low-level flow following a cold frontal passage. (The arrow is located just above the leading edge of this stronger flow.) Time lapse loops of the progress of this cold air surge have been prepared.
