21.   Moreover, with the sun lowering in the sky, surface temperatures decrease.

22.   Nonetheless, if surface temperatures and humidities soar, isolated severe thunderstorms could develop by evening, with large hail posing the greatest risk.

23.   Normally, Patzert said, the surface temperature of the tropical Pacific varies only a few degrees Fahrenheit through the course of a year.

24.   On the swordfishing boat, she had a color sounder, Doppler current indicator and surface temperature gauges.

25.   Rodwell showed that a large, positive winter index was tied to changes in sea surface temperatures off the U.S. coast the previous September.

26.   Smith and Kaufmann said the decline in the food supply might be related to an increase in surface temperatures during the same period.

27.   Surface temperature and sea levels are projected to increase for hundreds of years after stabilization of greenhouse gas concentrations.

28.   The British figures are one of two long-term data sets by which surface temperature trends are being tracked.

29.   The new observations of interaction between the cold South Equatorial Current and the warm North Equatorial Countercurrent included measurements of sea surface temperature.

30.   The preliminary Goddard figures differ from the British ones because they are based on a somewhat different combination of surface temperature observations around the world.
