FIG. 3. Recurvature-relative composite analyses of all recurving WNP TCs (N 5 292) at 36-h intervals for (a)–(g) T 2 72 to T1 144 h. Analyses show 250-hPa meridional wind anomalies (shaded according to the color bar, m s21; enclosed by black contours where significant at the 99% confidence level) and PV (blue, every 1 PVU). The TC symbol denotes the composite TC position, which is plotted for (a)–(f) T 2 72 to T 1 108 h. Solid and dashed black lines denote subjectively identified 250-hPa ridges and troughs, respectively.
