GOES satellite data assimilation project with R. McNider, A. Pour Biazar, and S.-O Han
from Baker et al. (2001, J. Hydrom.)
ENHANCEMENT
REDUCTION
from Gibson and Vonder Haar (1990 MWR)

N2 xx + (f2 – 2) zz = - Qx
• Hyperbolic (wavelike solutions) if (f2 – 2) < 0
• This happens within 30o of equator
• Aspect ratio of energy propagation and phase lines given by L/H = H/ (f2 – 2)1/2

Scientific Issues
• Convergence associated with complex coastline
• Nonlinear interaction with urban heat island
• Sea breeze front depth and convective initiation
• Role of large-scale inertial cycle and upward-propagating inertia-gravity waves
