What is a constant pressure surface? - Answer Maps that show areas of constant pressure, similar to constant height maps How are low and high heights related to temperatures below that pressure surface? - Answer Low heights mean cool air below High heights mean warm air below How do you identify ridges and troughs on an upper air map? - Answer Ridges have are at the top of a hill Troughs are at the bottom, like a valley What is the pressure gradient force? In what direction does it ac...

Low pressure systems - Answer air convergence is at surface, divergence is aloft high pressure systems - Answer convergence is aloft and divergence is at surface surface level convergence pushes air.. - Answer up clouds and precipitation come from - Answer rising air Troughs have divergence.. - Answer on the right, convergence on the left How do you strengthen a surface cyclone? - Answer When upper-level divergence is greater than surface convergence Air flow is faster at.. - A...
