When comparing the 500-mb pressure surface heights across the southern and northern US, it is apparent that the 500-mb surface height decreases with increasing latitude.
The pattern seen at 500 mb is the same as this one. The 500 mb height pattern frequently resembles a wave. Ridges and troughs are terms used to describe high and low points of waves, respectively. In general, ridges are associated with relatively warm air, whereas troughs are associated with very cold air. Closed contours are another aspect of the 500 mb design that is worth highlighting. A closed contour line is one that constricts in on itself, frequently taking the form of an oval or circle. There are closed highs as well as closed lows.
