They found this was true of cyclones that occur nearly all over the world, and they found that this trend of increasing maximum wind speed is correlated
with surface sea temperatures.
They also found that an increase of 1 ° C
in surface sea temperatures corresponds to an increase in the number of strong cyclones by as much as 30 percent per year.
Correlations between indices and the Atlantic multidecadal oscillation (AMO) index suggest that temperature variability and, to a lesser extent, precipitation extremes are related to the AMO signal of the North
Atlantic surface sea temperatures: stronger associations are found in August and September for the temperature indices and in June and October for some of the precipitation indices
How do you analyse the mismatch between modelisation of the pliocene climatic optimum with constraints on
the surface sea temperature derived from proxies and the proxies about temperatures and precipitations the pliocene climatic optimum?
The Surface Sea Temperature varies with make of probe.
And yes,
it surface sea temperature.
