In the United States, an El Niño is declared when the Climate Prediction Center, which monitors the sea surface temperatures in the Niño 3.4 region and the tropical Pacific, forecasts that the sea surface temperature will be .5 °C (0.90 °F) above average or more for the next several seasons. [107]

A wet-bulb temperature at 500 hPa in a tropical atmosphere of −13.2 °C (8.2 °F) is required to initiate convection if the water temperature is 26.5 °C (79.7 °F), and this temperature requirement increases or decreases proportionally by 1 °C in the sea surface temperature for each 1 °C change at 500 hpa.
The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats. It varies depending on depth, geographical location and season. Not only does the temperature differ in seawater, so does the salinity. Warm surface water is generally saltier than the cooler deep or polar waters. [1]
In January 1997, probes gathering information on deep water temperatures discovered an area of unusually warm water, centered around 150 meters depth, across the western half of the Pacific Ocean. About 150 m (490 ft) below the surface, water temperatures were about 3 °C (5.4 °F) above normal, signifying that an El Niño-Southern Oscillation ...
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 ...
The average temperature ranges between 21 and 31 °C (70 and 88 °F), with little seasonal variation. ... Bonechea died on 26 January 1775 in Tahiti and was buried ...
Climatology (from Greek κλίμα, klima, "slope"; and -λογία, -logia) or climate science is the scientific study of Earth's climate, typically defined as weather conditions averaged over a period of at least 30 years. [1]
