Sentences with phrase «circulation anomalies over»

While the ensemble forecast indicates an absence of significant atmospheric circulation anomalies over the western Arctic, high pressure features over the Barents sea appear to be conducive to greater ice extent reductions along the Eurasian side.

Summer atmospheric circulation anomalies over the Arctic Ocean and their influences on September sea ice extent: A cautionary tale.

Atmospheric circulation anomalies over the North Pacific become even stronger in the second winter relative to the first winter.

Not exact matches

LTP / ocean upwelling can generate low - frequency anomalies that look like increasing trends over very short (relative to ocean circulation) time scales.

Analysis showed that the AMV warming drives a modification of the Walker Circulation that creates precipitation anomalies over the whole tropical belt.

Anomalies in the volcanic - aerosol induced global radiative heating distribution can force significant changes in atmospheric circulation, for example, perturbing the equator - to - pole heating gradient (Stenchikov et al., 2002; Ramaswamy et al., 2006a; see Section 9.2) and forcing a positive phase of the Arctic Oscillation that in turn causes a counterintuitive boreal winter warming at middle and high latitudes over Eurasia and North America (Perlwitz and Graf, 2001; Stenchikov et al., 2002, 2004, 2006; Shindell et al., 2003b, 2004; Perlwitz and Harnik, 2003; Rind et al., 2005; Miller et al., 2006).

Over the coastal escarpment, the regression coefficients of temperature anomalies with the SAM are an indication that the SAM is tied with the surface energy balance and modulation of the thermally direct circulation as described by Parish and Bromwich (2007); the katabatic winds mix sensible heat towards the surface to balance longwave cooling (van den Broeke et al. 2006).

This report discusses our current understanding of the mechanisms that link declines in Arctic sea ice cover, loss of high - latitude snow cover, changes in Arctic - region energy fluxes, atmospheric circulation patterns, and the occurrence of extreme weather events; possible implications of more severe loss of summer Arctic sea ice upon weather patterns at lower latitudes; major gaps in our understanding, and observational and / or modeling efforts that are needed to fill those gaps; and current opportunities and limitations for using Arctic sea ice predictions to assess the risk of temperature / precipitation anomalies and extreme weather events over northern continents.

Anomalies in the volcanic - aerosol induced global radiative heating distribution can force signifi cant changes in atmospheric circulation, for example, perturbing the equator - to - pole heating gradient (Stenchikov et al., 2002; Ramaswamy et al., 2006a; see Section 9.2) and forcing a positive phase of the Arctic Oscillation that in turn causes a counterintuitive boreal winter warming at middle and high latitudes over Eurasia and North America (Perlwitz and Graf, 2001; Stenchikov et al., 2002,2004, 2006; Shindell et al., 2003b, 2004; Perlwitz and Harnik, 2003; Rind et al., 2005; Miller et al., 2006).
