Document Summary

A: all values at that pressure level are the same. (e. g. , 850 mb) A: low heights cooler temperatures high heights warmer temperatures (expanded height columns warm air expands) A: trough extension of lower pressure/heights (u-shape) Ridge extension of higher pressure/heights (mountain shape) A: pgf acts perpendicular to height contour lines towards lower heights/pressures also, pgf causes the wind to blow. A: stronger pgf = stronger wind speeds closer the height/pressure lines are together = stronger. A: the cf is an apparent force that causes objects to appear to deflect in the rotating reference frame. The cf acts 90 to the right of the wind in the n. h. only changes the direction, not the speed of an object. A: the faster the wind speed, the more the cf has an effect. A: no, the cf does not influence small-scale flows remember the rossby number!
