Sentences with phrase «sea level pressure field»

Figure 1 (below) is the sea level pressure field for June and July 2009, showing the Dipole / negative Arctic Oscillation pattern with high pressure on the North American side of the Arctic.

The Northwest Pacific basin has a lower background sea level pressure field.

The figure below (Figure 5 a-c) provided by Cecilia Bitz, and similar plots provided by Oleg M. Pokrovsky and the NIC Group, shows the sea level pressure field centered over the Northern Hemisphere for July 2008, July 2007, and for July average conditions (climatology).

Unlike the sea level pressure field from the last six years with the Arctic Dipole (AD), which has low pressure on the Siberian side of the Arctic and higher pressure on the North American side, May 2013 had a low pressure over the central Arctic.

Predictor variables: C = circulation based (e.g.: sea level pressure fields and geopotential height fields).

I'm using sea level pressure fields from ERA - interim reanalysis and from the 20th century reanalysis.

For stratospheric circulation (which impacts strat - trop exchange, high latitude sea level pressure fields), we tune the GW drag.

Not exact matches

This approach may not be useful for quantitative reconstructions of past spatial patterns of climate fields, e.g. surface temperature, sea level pressure, drought, etc..

Patterns of anomalously high sea levels are attributed to El Niño — related changes to atmospheric pressure over the Gulf of Mexico and eastern Canada and to the wind field over the Northeast U.S. continental shelf.

The change in May is explained by the sea level pressure (SLP) and air temperature anomaly field for May (Figure 8, top).

The normal sea level pressure climatology for the summer Arctic has been a flat field or a weak monthly mean low pressure center over the Arctic.

This is particularly found in changes to the surface air temperature, sea level pressure (Fig. 3), and 500 - hPa geopotential height fields.

The quasi-global sea - surface temperature and quasi-global sea - level pressure fields are found to be the most useful predictors.

These metrics emphasise fields between 30S and 30N including 2 m air temperature (Willmott and Matsuura 2000), vertically averaged air temperature (ERA40, Uppala et al. 2005), latent heat fluxes of the ocean (Yu et al. 2008), zonal winds at 300 mb (ERA40, Uppala et al. 2005), longwave and shortwave cloud forcing (CERES2, Loeb et al. 2009), precipitation over land and ocean (GPCP, Adler et al. 2003), sea level pressure (ERA40, Uppala et al. 2005), vertically averaged relative humidity (ERA40, Uppala et al. 2005).

As there are numerous techniques for determining sea level pressures from atmospheric observations, all having limitations, we also compared the SLP fields generated in the above way for general consistency with those generated using an independent method.

Lukovich et al. (Centre for Earth Observation Science, U. of Manitoba); 4.4 to 4.5; Heuristic - Dynamics The absence of a strong and persistent sea level pressure high over the Beaufort in July together with the absence of spatial homogeneity in the springtime sea ice drift fields suggest that continued sea ice decline will be an artifact of increased temperatures and thermodynamic forcing rather than the considerable dynamical contributions seen in summer of 2007.

I've also never seen a paper (haven't looked for one, truth be told) about the relationship between the magnetic field and sea level pressure.
