It's also an area where there is less seasonal variability — it more or less feels like summer all year. (sciencedaily.com)
However, it appears that the constrained best - estimate for ECS that Zhai et al. derive is simply the unweighted mean and standard deviation of ECS values for the seven models having seasonal variability derived relationships of low cloud extent with SST that are consistent with their observational estimate.
