Figure 3: Model forecast total air-sea enthalpy fluxes (W/m2, shading), together with snapshots of instantaneous 17.5 ms-1 surface wind field (blue contours) and wind direction (black arrows), 150 m isobath (black dashed line), and forecast TC track (brown lines and triangles), for: (a) Sally, (b) Hanna, and (c) Eta. Insets show vertical wind shear between 850 and 200 mbar, maximum 10 m wind speed [ms-1], and minimum sea-level pressure [hPa] at that forecast hour.
