Abstract : The effect of resolution on the depiction of central sea-level pressure for an intense oceanic extratropical cyclone is examined through a one-dimensional Fourier analysis. Profiles of sea-level pressure were manually interpolated along the latitude passing through the storm center from two subjective analyses and the 00, 24, and 48 h Nested Grid Model (NGM) forecasts, all valid at 0000 UTC 5 January 1989. At this time, the Experiment on Rapidly Intensifying Cyclones over the Atlantic (ERICA) Intensive Observing Period 4 (IOP-4) cyclone attained its maximum intensity, with a central pressure of 936 mb at 41 deg N 58 deg W in an analysis prepared by Prof. Frederick Sanders.
