Fig. 5: Climatological (1991–2020) Potential Intensity (PI) and Dynamic Potential Intensity (DPI) under given thermodynamic environment of the atmosphere and the upper ocean.
From: The North Equatorial Current and rapid intensification of super typhoons
Spatial distributions of (a) PI, (b) DPI, and (c) sea surface temperature cooling (shading/contours, see Methods) computed from the season-mean (June–November) European Center for Medium-Range Weather Forecasts (ECMWF) reanalyses (the fifth generation ECMWF atmospheric reanalysis (ERA5) and Ocean Reanalysis System 5 (ORAS5)) and DPI from (b). All grid points (0.25° × 0.25°) were forced by the typical CAT5- tropical cyclone (TC) characteristics inspired from Mangkhut: maximum sustained wind speed of 70 m s−1; radius of maximum wind of 35 km; TC translation speed of 5 m s−1. The two black boxes in the western North Pacific represent the Eddy Rich Zone and North Equatorial Current regions, respectively.
