Water plays a major role for our planet not only in its liquid form at the surface.
Global surface

water up from the depths of the
Pacific ocean and released the energy into the atmosphere.
The best way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian
Ocean as a mirror of the
Pacific Ocean sea surface
temperature anomalies [much like the Western Hemisphere Warm Pool creates such a SST mirror with the Atlantic
Ocean too]: during a La Niña episode,
waters in the eastern
Pacific are relatively cool as strong trade winds blow the tropically Sun - warmed
waters far towards the west.
The

Figure 15 - A has shown the global pacing by the El Niños (and their tele - connections) of the

Pacific warm pool, as they move to higher latitudes on the western rim of the
oceans after an El Niño.
Observations suggest that variability in oceanographic conditions in the Arctic is very largely driven by the consequences of the flows through open passages to both Atlantic and
Pacific Oceans, which themselves respond to the different and characteristic variability of the circulation patterns of each
ocean: each inflow is not only variable in volume of
water transported but also in the
temperature of the
water imported.
In any year,

The current bleaching event has affected reefs throughout the tropics — including much of the

He proposes a relationship between the
Pacific Decadal Oscillation (PDO) and clouds by considering a variety of combinations of initial
ocean temperature,
ocean thickness, cloud feedback, and forcing by clouds (neglecting forcing by CO2 and the
water vapor feedback entirely) in a simple energy balance model, and finds a relationship between PDO and clouds using 9 years of satellite data.
There was so much warm
water released by the 1997/98 El Niño that the sea surface
temperatures for the entire East
Pacific Ocean (from pole to pole or the coordinates of 90S - 90N, 180 - 80W) temporarily warmed 0.5 to 0.6 deg C. See Figure 4.
The leftover warm
water (and its counteracting effects on the trailing La Niña) is why the sea surface
temperatures for the Atlantic, Indian and West
Pacific Oceans warmed in a very obvious upward step of about 0.19 deg C, Figure 5, in response to the 1997/98 El Niño.
Reduced equatorial cloud cover during La Nina (due to the cooler sea surface
temperature), combined with the strong upwelling (Ekman suction) in the eastern equatorial
Pacific, does indeed lead to greater warming of the
ocean - because it's bringing cool subsurface
water to the surface, where it can be heated by the sun.
