Figure 4: The mechanism of the IPO remote influence on Indian Ocean decadal variability.
From: The Footprint of the Inter-decadal Pacific Oscillation in Indian Ocean Sea Surface Temperatures
Decadal difference patterns between the IPO warm phase from 1977–1998 and the IPO cold phase from 1951–1976 (i.e., 1977–1998 minus 1951–1976) for (a) sea level pressure (hPa) from HadSLP2 and surface zonal wind vectors (m/s) from JRA-55 reanalysis, (b) same as (a) but from one piControl + TEP SST run, (c) sea surface height (cm) and zonal wind stress vectors (dyne/cm2) from the piControl + TEP SST run, and (d) ocean potential temperature (°C) averaged over 15°N–15°S from the piControl + TEP SST run. Note that the SLP in (a) is 1977–1998 minus 1958–1976 due to the time limitation of the HadSLP2 dataset. The dotted areas are statistically significant at the 5% level based on a Student’s t-test. This plot was created by NCAR Command Language43.
