  1. The Effect of the Complex Coastline in the Houston Area John Nielsen-Gammon Texas A&M University

  2. Land Use Classification Stephen Stetson, Global Environmental Management, Inc.

  3. GOES satellite data assimilation project with R. McNider, A. Pour Biazar, and S.-O Han

  4. REDUCTION ENHANCEMENT from Baker et al. (2001, J. Hydrom.)

  5. from Gibson and Vonder Haar (1990 MWR) Cloud (2 PM CST) Cold Cloud

  6. from Marshall et al. (2004 MWR) pre-1900 1993

  7. N2yxx + (f2 – w2) yzz = - Qx • Hyperbolic (wavelike solutions) if (f2 – w2) < 0 • This happens within 30o of equator • Aspect ratio of energy propagation and phase lines given by L/H = H/ (f2 – w2)1/2 (from Rotunno 1983)
