Geopotential Height and Temperature at 500 hPa |
| Description: |
The maps show the predominant tropospheric waves (trough or ridge). They virtually control
the "weather" (wet, cold / dry, warm) and the long waves drive the smaller synoptic waves.
Thus, this upper-level chart illustrates the dynamics of our atmosphere.
