### Wind-induced ocean mixing ### Wind-induced ocean mixing
We evaluate the sensitivity of tropical Pacific SST response to 4xCO2 forcing based on differing wind-induced ocean mixing (cwt/cwa=0.5e-3 as default). We evaluate the sensitivity of tropical Pacific SST response to 4xCO2 forcing based on differing wind-induced ocean mixing (cwt/cwa). The default cwt/cwa is 0.5e-3 and we tested with a doubling, quadrupling and halving the default value.
Control experiments with 4 different cwt/cwa choices. * Control experiments with 4 different cwt/cwa choices

For each wind-induced ocean mixing param (cwt/cwa) setting, we branch off multiple 4xCO2 runs. Additionally, we take into consideration the equatorial Pacific state (El Niño, La Niña, neutral) during initialisation. Since we are interested in fast reponse, each ensemble member is only integrated for 20 years. For each wind-induced ocean mixing param (cwt/cwa) setting, we branch off multiple 4xCO2 runs.

Restart files from control run were only saved once a year, on the last day of the year, i.e. yyyy-12-31. Hence, we can only branch from that date. Restart files from control run were only saved once a year, on the last day of the year, i.e. yyyy-12-31. Hence, we can only branch from that date.
