I like plotting the east - west (zonal) component like this, with a gray scale — it gives one the feeling of looking at a 3d contour map of sea - level pressure, lighted from the south in the Southern Hemisphere and from the north in the Northern Hemisphere (because the east - west component of the winds is closely related to the north - south gradient of the pressure).

While derived from sea surface temperature data, the PDO index is well correlated with many records of North Pacific and Pacific Northwest climate and ecology, including sea level pressure, winter land — surface temperature and precipitation, and stream flow.

A persistent ridge of higher than normal sea level pressure was present over the Gulf of Alaska from October 2013 into February 2014.

The Arctic had a weak Dipole Sea Level Pressure (SLP) with a low on the Eurasian Side and a high pressure region from north of the Bering Strait across northern Canada; the SLP pattern is typical of the long term average (1981 Pressure (SLP) with a low on the Eurasian Side and a high pressure region from north of the Bering Strait across northern Canada; the SLP pattern is typical of the long term average (1981 pressure region from north of the Bering Strait across northern Canada; the SLP pattern is typical of the long term average (1981 - 2010).

Anyway, one of the things on my todo list is to look into where the pressures used to adjust sea level data come from.

The station component is a blend of many national and international collections, with the largest contributor being surface and sea level pressure observations from the International Surface Database (ISD, Lott et al., 2008).

A balance develops between the Coriolis force and the force arising from the horizontal water pressure gradient such that surface currents flow parallel to the contours of elevation of sea level.

(Top) Time series of the NPI (sea level pressure during December through March averaged over the North Pacific, 30 ° N to 65 ° N, 160 ° E to 140 ° W) from 1900 to 2005 expressed as normalised departures from the long - term mean (each tick mark on the ordinate represents two standard deviations, or 5.5 hPa).

These graphs show sea level pressure anomalies or differences from average sea level pressure in the Northern Hemisphere for April, May, June, and July 2016.

That method, which we use in the NASA / GISS GCM, extrapolates the surface pressures to sea level based on elevation and the atmospheric lapse rates calculated from surface air temperatures.

In July, the Arctic Dipole Anomaly (DA) pattern that was dominant in June (which promotes clear skies, warm air temperatures, and winds that push ice away from coastal areas and encourages melt) was replaced by low sea level pressure (SLP) over the Arctic Ocean, leading to ice divergence (ice extent «spreading out») and cooler temperatures.

This is an increase of 1 million square kilometers from the July Outlook, reflecting the persistence of low sea level pressure (SLP) over the central Arctic that resulted in ice divergence and a more fractured ice cover.

We use the 9 climate variables of surface air temperature (SAT), sea level pressure (SLP), precipitation (rain), the top of atmosphere (TOA) shortwave (SW) and longwave (LW) full - sky radiation, clear - sky radiation (CLR, radiative flux where clouds do not exists), and cloud radiative forcing (CRF, radiative effect by clouds diagnosed from the difference between full - sky and clear - sky radiation, Cess et al. 1990).

This plot shows Arctic sea level pressure difference from average for September 2016.

Correlations with the SOI, based on normalised Tahiti minus Darwin sea level pressures, for annual (May to April) means for sea level pressure (top left) and surface temperature (top right) for 1958 to 2004, and GPCP precipitation for 1979 to 2003 (bottom left), updated from Trenberth and Caron (2000).
