The Impacts of Satellite Remotely Sensed Winds and Total Precipitable Vapour in WRF Tropical Cyclone Track Forecasts

Figure 4

Eliassen-Palm flux and its divergence in isentropic coordinates valid at 8 times for figures (a)–(h) at 6-hr intervals. The horizontal and vertical components of E-P fluxes have units of kg m K⁻¹ s⁻² and kg s⁻², respectively. The shades for the divergence of the E-P flux have 5 × 10³ kg K⁻¹ s⁻², with positive regions shaded with warm colors. The horizontal axis indicates the distance from the storm center. Only values within a 300 km radius of the storm center are shown.
