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...

Which gases are the primary constituents of the atmosphere? - Answer 99% nitrogen and oxygen What is the difference between weather and climate? - Answer Weather- atmospheric conditions at a specific time and place (temp, pressure, humidity, cloud cover) Climate- Average weather over a long period of time (10+ years)(record highs and lows, statistical analysis) -climate is what you expect, weather is what you get What is the difference between satellites and radar? - Answer satellites- v...

Which gases are the primary constituents of the atmosphere? - Answer Oxygen (21%) and Nitrogen (78%) Difference between weather and climate - Answer -Weather is the conditions particular in a tame in place (What you get) -Climate is the average weather over a long period of time What is the doppler radar? - Answer Can sense motion of perception particles How is wind direction defined? - Answer From the way its blowing The difference between satellites and radar? - Answer -satellites...

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...

Constant Pressure - Answer A surface in the atmosphere where the pressure is equal everywhere along that surface Higher heights=____;Lower heights=____. - Answer Warmer air;colder air Isotherms - Answer Lines of equal temperature Ridges - Answer Elongated highs where air is warmer and indicating depressions Troughs - Answer Elongated lows where air is colder. Pressure gradient force (PGF) - Answer Directed from higher towards lower pressure at right angles to the isobars; force th...

What is pressure and how does it change with height? - Answer Pressure is the mass of air above a given level. Pressure = weight/area Pressure = force/area Pressure always decreases with height. What is the difference between satellites and radar? - Answer Satellites view clouds from space. Radar views precipitation from the ground. How is wind direction defined? - Answer Wind direction is defined by the direct from which the wind is blowing. What is density and how does it change wit...
