I can't help but notice that the St. Vincents Gulf temperature now is 22 C, including something like a 3 C positive anomaly, whereas the normal winter air temperature in Adelaide may be something like 12 C. Using «cooling tower» calculations, I think it should be possible to heat up the air by contacting it with 22 C sea water raining through it to a temperature of at least 18 C.
My understanding is that an Anomaly is the average temperature variation over a period relative to a baseline, if the temperature is greater it results in a positive anomaly, if it is equal to the baseline then there is zero anomaly and if it is less than the base line it is a negative anomaly.
Positive Anomaly over one period doesn't mean increasing temperature, periods of positive anomaly do, as the ongoing average increases.
Because the water holding capacity of the atmosphere increases exponentially with temperature (e.g., Trenberth et al. 2003), a positive anomaly on top of already high SSTs has much greater effect than if located elsewhere.
