dear all,
myself suman maity.i have a question regarding "geopotential height".
the question is when we are plotting the geopotential height of a particular level
(say 500hPa or 300 mb) then what meteorological information we can get from that plot?
that means i want to know what is the reason for plotting geopotential height?
 
 
please answer.it's urgent.
