East 1 sector longitudes (yellow shading). 200-hPa streamfunction anomaly composites in 106 m2/s for (a) analog, (b) AR, and (c) top AR timesteps averaged over the four-day period prior to AR landfall (dark blue contours). Statistically significant differences in the percentage of timesteps with outgoing longwave radiation below 220 W/m2 from 20°S to 20°N between (b) AR and Analog timesteps, (c) top AR and AR timesteps (purple and pink shading) four days prior to AR landfall.
