Some geoscientists think the first ocean was extremely hot (at least 70 degrees Celsius), while others believe it was closer to today's levels, around 15 degrees. Both sides rely on changes in the oxygen isotope composition of minerals precipitated out of seawater (for example, found in the ...
One manifestation of such weather-affecting interactions between the ocean and the atmosphere is what scientists call the El Niño/Southern Oscillation (ENSO). It is believed that ENSO is responsible not only for unusual weather events in the equatorial Pacific region (e.g., the exceedingly ...
The picture worsens with each round of El Nino, the unusually warm currents in the Pacific Ocean that drive uptemperaturesand invariably presage (预示) droughts and fires in the rain forest. 出自-2013年6月阅读原文 It was a method of refrigeration which rolls from his work in lowtemperaturephys...
Daytoday variations in SST show weak periodicity over an 816 day range. Air temperatures are generally cooler and shortterm fluctuations have 34 times the standard deviation of the SSTs. Seasonal SST variations are described and coastal SSTs are compared with offshore SST data. At Farewell Spit ...

Also of importance is the time when observations are made each day. Even today there is no accepted standard, countries being allowed to choose whatever times suit them. English-speaking countries have tended to use the average of the daily maximum and minimum readings each day to measure daily...
El Niño, a broad-scale weather pattern now developing, begins with a warming of waters in the eastern tropical Pacific Ocean. That, historically, has been linked to split-flow jet stream patterns like the one driving wild weather across parts of the Lower 48. ...
El Niño describes the warming of the Pacific Ocean due to a lack of wind, which alters the depth of the thermocline. This warming in turn affects weather and temperature patterns across the globe 35. La Niña is the opposite condition of the ocean, where temperatures are cooler than ...
