Document Summary
Wind that is the response between the pgf and the cf. Apparent deflection due to rotation of the earth. Right in northern hemisphere and left in southern hemisphere. Circulation around center of low pressure is called cyclonic, circulations around center of high pressure is called anti-cyclonic (irrespective of hemisphere) Upper air data is taken from balloons which measure upper air conditions over a particular location. This includes plots of data on the standard mandatory and height levels, contours of various upper air parameters and a set of sounding plots for most us sites. These data updates once every 12 hours around 9:45 est. Cross section in height (3,000m) of the atmosphere if the temperature is not the same across the surface then the pressure will differ. Low pressure goes in, high pressure goes out. Early attempts to understand the general features of atmospheric circulations were based on the concept of single cell model.
