Jerome Namias and Robert Born hypothesized that patterns in the variability of this quantity recur from winter to winter via a so-called “re-emergence” mechanism. This quantity’s namesake Optimum Interpolation dataset is built using data from AMSR and AVHRR. The bulk value for this quantity is derived from its skin value as measured by radiometers on MODIS and other satellites. Changes in this quantity characterize the (*) Indian Ocean Dipole, which is a climate pattern driven by Bjerknes (“b’yehrk-ness”) feedback. The variation of this quantity with an approximate period of 65 to 80 years in the North Atlantic is called the Atlantic Multidecadal Oscillation. Low values of this quantity alongside high chlorophyll a concentrations are a common indicator for upwelling zones. For 10 points, what quantity is abnormally high during the El Niño phase of the ENSO? ■END■
ANSWER: sea surface temperature [or SST or ocean surface temperature; accept bulk sea surface temperature or bulk SST; accept skin sea surface temperature or skin SST; prompt on ocean temperature; prompt on surface temperature]
