Sentences with phrase «average sea surface temperature departure»
The Oceanic Niño Index, the three - month - average sea surface temperature departure from the long - term normal in one region of the Pacific Ocean, is the primary number we use to measure the ocean part of El Niño, and that value for November — January is 2.3 °C, tied with the same period in 1997 - 98.

El Niño: A phenomenon in the equatorial Pacific Ocean characterized by a positive sea surface temperature departure from normal (for the 1971 - 2000 base period) in the Niño 3.4 region greater than or equal in magnitude to 0.5 degrees C (0.9 degrees Fahrenheit), averaged over three consecutive months.
This February's sea surface temperatures were 1.46 degrees above average, which means the past nine months have been the nine highest monthly global ocean temperature departures on record.
The «Temperature Departure From Average» map below further reveals the areas of concentration for climate engineering orchestrated chemical cool - downs and sea surface chemical ice nucleation (also fueling extreme hail events).
This was warm enough to set another milestone that had already been set two previous times this year; the average global sea surface temperature was so warm in September that it broke the all - time record for the highest departure from average for any month since 1880, at 1.19 degrees Fahrenheit above average.
However, for changes over time, only anomalies, as departures from a climatology, are used, most commonly based on the area - weighted global average of the sea surface temperature anomaly and land surface air temperature anomaly.
La Niña events are operationally defined using the Oceanic Niño Index (ONI), which is the three - month running - mean values of sea surface temperature departures from average in the Niño 3.4 region of the central Pacific (bounded by 5N - 5S, 120 - 170W).
