Hi Ed,

Working day in day out with models exposes model strength and
weakness. The ETA has done an awful job on development and timing of
precipitation in the southern US over the past year, especially when
southern branch energy is invoved. The ETA is too dry and too slow. It
used to be a great model for just this type of weather but not any
more. The ETA has been overdeveloping low pressure areas along the
southeast coast over the past couple of years, while the GFS can be
underdone in the same situation. AVN MOS seems to be the most reliable
for high temps when clouds and rain are a good bet. These are some
examples and there are many more that will creep up day in day out.

Hope this helps

Hello.

Can someone tell me the advantages/disadvantages of the following numerical
weather models in terms of weather forecasting?

ETA
MRF
MOS
NOGAPS
GEM

Specifically, I would like to know what the strengths and weaknesses of
these models are when using them to produce a weather forecast. If I am
missing any models, feel free to add them.

Thanks

Ed
