There definitely appears to have be a disturbance in Sea Surface Temperature between May 9th and 19th, Furthermore, the disturbance wasn't just SST, it was
also Sea Surface Height;
Not exact matches
Because water expands as it warms, that heat
also meant that
sea surface heights were record high, measuring about 2.75 inches higher than at the beginning of the satellite altimeter record in 1993.
They
also measure a slightly different vaeiable:
sea surface height (aka geocentric
sea level, ie the
height of the
sea surface relwtive to the planet's center of gravity, rather than
sea level proper, aka relative
sea level, ie
height of the
sea surface relative to the solid Earth).
The second is what is termed as «steric change» — a scientific phrase that both identifies ocean thermal expansion due to warming combined with changes in ocean salinity, which
also impacts
sea surface height.
Another paper, [7] which they
also cite, instead derives an equilibrium air —
sea surface warming differential from a theoretical model based on an assumed relative humidity
height profile, with thermal inertia playing no role.
They
also find that the primary contribution to storm surges in the region are
sea surface height anomalies from the Pacific, with local wind patterns causing small spatial differences in the
sea surface height.
