A ridge is an area on the chart where the height contours have shifted poleward (i.e. north in the northern hemisphere). It looks like an inverted 'U'. As my esteemed meteorology professor repeated many times, 'WARM columns are TALL columns'. Warming the air increases the volume, so it becomes taller. This shows up as the poleward shift of isohypses on a map, and thus a ridge.

Explain why a ridge in the 500-mb flow pattern is associated with a pool of relatively warm air.?
Higher heights are associated with warmer air. As you move south across a ridge, the temperature increases and therefore the height increases. The opposite happens in troughs, where low heights mean colder air. As you move north across a trough, the temperature decreases and therefore the height decreases. All of this is true for the Northern Hemisphere.Explain why a ridge in the 500-mb flow pattern is associated with a pool of relatively warm air.?
