Sentences with phrase «timescale fluctuations in temperature»

If the validation period does not have as strong a trend and the proxies are not skillful at predicting shorter timescale fluctuations in temperature, then the CE can be substantially lower.

Not exact matches

It is a big enough perturbation on timescales of multiple decades or longer to dominate the temperature pattern on a global scale, despite the existence of chaotic elements responsible for fluctuations in the temperature trend globally that average out, and despite significant unpredictability regionally.

In conclusion, our analysis suggests that strong interannual and decadal variations observed in the average land surface temperature records represent a true climate phenomenon, not only during the years when fluctuations on the timescale of 2 - 15 years had been previously identified with El Nino eventIn conclusion, our analysis suggests that strong interannual and decadal variations observed in the average land surface temperature records represent a true climate phenomenon, not only during the years when fluctuations on the timescale of 2 - 15 years had been previously identified with El Nino eventin the average land surface temperature records represent a true climate phenomenon, not only during the years when fluctuations on the timescale of 2 - 15 years had been previously identified with El Nino events.

«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»

And, in fact, when one looks at temperature fluctuations that occur on the timescales of months to a few years, you do in fact see this amplification.

The research appears to indicate that the short - term fluctuations in solar activity, though they discernibly cause the short - term cycles global temperatures in a manner that the monotonic increase in CO2 manifestly does not, are absolutely predictive of global temperature change on all timescales provided that the time - integral of the solar - activity change is taken.
