The sea surface temperature (SST) of the West Pacific northeast of Australia averages around 28–30 °C (82–86 °F). SSTs in the East Pacific off the western coast of South America are closer to 20 °C (68 °F). Strong trade winds near the equator push water away from the East Pacific and towards the West Pacific. [22] This water is slowly ...
Interdecadal temperature variations in China are closely related to those of the NAO and the NPO. The amplitudes of the NAO and NPO increased in the 1960s and interannual variation patterns changed from 3–4 years to 8–15 years. Sea level rise is affected when large areas of water warm and expand, or cool and contract.

The temperature range of the sinking North Pacific Subtropical Mode Waters characteristically falls between 16 °C and 19 °C, however exact temperatures and depths to which these waters sink varies annually depending on the efficiency of water transportation by the extension, which is a function of atmospheric and mesoscale eddy conditions.

In fact, the temperature of the Pacific cold tongue is the defining feature of the ENSO (El Niño-Southern Oscillation). An El Niño condition is officially recognized when the mean sea surface temperature in the Pacific cold tongue is more than 0.5 °C above average for a given time of year, whereas a La Niña condition is recognized when the ...
Map of pressure systems across North America. A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather.The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).
Marine weather forecasts by various weather organizations can be traced back to the sinking of the Royal Charter in 1859 and the RMS Titanic in 1912. The wind is the driving force of weather at sea, as wind generates local wind waves, long ocean swells, and its flow around the subtropical ridge helps maintain warm water currents such as the ...
