A Survey on the Relationship between Ocean Subsurface Temperature and Tropical Cyclone over the Western North Pacific

Figure 8

Composite anomalies of (a) absolute vorticity (units: ), (d) relative humidity (units: %), and (g) vertical wind shear (units) in JASON season for the subsurface cold years; (b), (e), and (h) as in (a), (d), and (g), but for the subsurface warm years; (c), (f), and (i) for the difference of composite anomalies between subsurface cold and warm years (cold-warm). Dashed rectangle indicates the main TC genesis area of southeastern quadrant mentioned in Section 4.2. The cross signs indicate that the values are statistically significant at the 95% confidence level.
