. Assignment 12. Due April 15


Purpose: (1) to analyze manually the 500 mb geoptential height field. (2) to use geostrophic and gradient wind relationships to

  • Review the information on geostrophic and gradient wind balance in the Djuric text.

  • 1. Analyze the 500 mb geopotential height field at 60 m interval (about 5520 m) for 12Z April 8, 2003. Use the geostrophic and gradient wind scales to relate the observed wind speed to deduce the appropriate local height gradient.
  • 2. Compute the geostrophic and gradient wind speed and direction at OTX, DNR, OUN, ILN.
  • 3. Estimate the direction and magnitude of the ageostrophic wind at those four locations.
