Figure 8: Air temperature (K) at 925 hPa in JJA for: (a) anomaly for weak HC cases, (b) anomaly for strong HC cases. Correlation between austral winter HCI and: (c) air temperature (K) at 925 hPa, (d) stationary wave geopotential height at 500 hPa. The contour interval is 0.2 K in (a) and (b) and the statistically significant values at the 90%, 95%, and 99% levels according to a two-tailed Student’s -test are shaded in grey scale (see vertical bar). The contour interval is 0.2 in (c) and (d), and regions exceeding 95% significance level (> ) are shaded.
