The linear regression of JJAS mean OHT averaged over 5°S−5°N on zonal mean meridional streamfunction anomalies averaged for (a) SON, (b) DJF, (c) MAM(+1) and (d) JJA(+1) from 1998-2018. The stippling indicates statistically significant regression coefficients at 95% confidence level as revealed by a two-tailed Student’s t-test.
