Mean state change over the tropical Indian Ocean.
(a) Map showing the multi-model ensemble mean SON change (RCP8.5 minus historical) in SST (colours) and precipitation (contours, negative values are dashed). The green contours mark where the change in precipitation is significant at the 95% confidence level. The change in SST is significant everywhere at the 95% confidence level. (b) As in (a) but for thermocline depth (ZT, colours) and wind stress (vectors). Black vectors are where the zonal or meridional wind stress change is significant at the 95% confidence level. The green contours show where the ZT change is significant at the 95% confidence level. The significance for (a) and (b) is calculated using Student's two tailed t-test. (c) Scatter plot showing the relationship between the change in IODE SST skewness (RCP8.5 minus historical) and the ratio of mean thermocline depth for the RCP8.5 and historical simulations. All maps and plots were generated in NCL.
