1. Using the latest 80 km CONUS North American Model (NAM) data, create a display of color filled contours of sea level pressure, 500 hPa heights and isosurface of wind speed.
2. Display sea level pressure as contours draped over topography.
3. Create display of geopotential height contours at 500 mb on a topography surface of the pressure from the lates.
   • Create a color filled contour display of geopotential height over topography. When prompted for the topography field, select geopotential.
   • Now do the same for contours over topography.
   • Turn sharing for both displays.
   • Set the level to 500 hPa.
   • Set the vertical scale to 4800 to 6000 meters to exaggerate the effect.
