Sentences with phrase «influencing circulation trends»

Not exact matches

In fact, Cane et al (1997) argue that the tendency toward increased SST gradient is precisely what is seen if one uses a robust trend analysis to decrease sensitivity of the trend analysis to outliers such as the very large 1982/1983 El Nino event (this event, and the equally large 1997/1998 El Nino event, greatly influence the estimate of a weakening trend of the Walker circulation in Vecchi et al).

The available data are insufficient to say if the changes in O2 are caused by natural variability or are trends that are likely to persist in the future, but they do indicate that large - scale changes in ocean physics influence natural biogeochemical cycles, and thus the cycles of O2 and CO2 are likely to undergo changes if ocean circulation changes persist in the future.

Detection / attribution assessments, using General Circulation Models (GCMs) or Energy Balance Models (EBMs) with geographical distributions of surface temperature trends, suggest that the solar influence on climate is greater than would be anticipated from radiative forcing estimates.
