Calculate Cold Air Drainage from DEM?

I am trying to figure out how to calculate cold air drainage from a DEM.  I need to map areas that have an elevation change of 30m within a 750m radius and am not sure how to do this exactly.

I basically need every cell in the DEM to search a radius 750m to determine if the elevation changes more than 30m.  If it does, then I need it to be reflected in it's attribute table.

Any ideas?
