Sentences with phrase «hpa geopotential»

The first principal component is significantly correlated with the SAM index (the first principal component of sea - level - pressure or 500 - hPa geopotential heights for 20u S — 90u S), and the second principal component reflects the zonal wave - 3 pattern, which contributes to the Antarctic dipole pattern of sea - ice anomalies in the Ross Sea and Weddell Sea sectors.

The SLP fields used in this atlas are derived from the 12 - hourly (0Z and 12Z) 500 HPa and 1000 HPa geopotential heights generated by the NCEP Reanalysis project.

I include in this week's blog the monthly 500 hPa geopotential heights (Figure 11) and the surface temperatures (Figure 12) forecast for June from the Climate Forecast System (CFS; the plots represent yesterday's four ensemble members).

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

For example figure 7 is the 6 — 10 day outlook for 15 — 19 August, made on 9 August 2008, for 500 hPa geopotential height field (solid) and anomalies (dashed, DNS = departure from normal); earlier weather outlooks in August were similar.

The PNA (left) and NAO (right) teleconnection patterns, shown as one - point correlation maps of 500 hPa geopotential heights for boreal winter (DJF) over 1958 to 2005.
