Cross-section - frontogenesis and lapse rate
Notes:
This slide shows frontogenesis (contoured) and equivalent potential temperature lapse rate (values less than 1 degree C per km shaded) at 12z on the 2nd and 00z on the 3rd. The front is annotated. Reduced lapse rates (less than 1 degree C per km) can be seen just above the frontal zone at 00z on the 3rd, indicating an increased potential for an enhanced frontal circulation around that time.
