Tracer Advection Using Dynamic Grid Adaptation and MM5

Monthly Weather Review, 2005
Abstract A dynamic grid adaptation (DGA) technique is used to numerically simulate tracer transport at meso- and regional scales. A gridpoint redistribution scheme is designed to maximize heuristic characteristics of a “good” grid. The advective solver used in conjunction with the DGA is the multidimensional positive definite advection ...

Evaluation of Surface Fluxes from MM5 Using Observations

Monthly Weather Review, 1995
Abstract Direct observations of surface fluxes of momentum, sensible, and latent heat from towers and aircraft are compared to output from the NCAR-Penn State Mesoscale Model MM5. The model flux parameterization is seen to work well if appropriate values of the roughness length z0 and moisture availability parameter M are specified.

Introduction to Adjoint Techniques and the MM5 Adjoint Modeling System

1997
Adjoint models are increasingly applied to many problems in meteorology and oceanography. The adjoint model of MM5 is a tool which effectively computes the gradient (or a Gateau-derivative) of any MM5 forecast aspect with respect to the model's control variables, which consist of model initial conditions, boundary conditions, and model parameters that ...

Forecast Model Uncertainty; MM5 Accuracy Over Utah

2004
Abstract : Researchers are investigating various approaches to determine and portray weather forecast uncertainty. Methods requiring extensive computing power on the battlefield or massive data communications to the end user will not be implemented in the near future.
