This is where I think the pluses of the established meteorological 
society will be: We know how to establish the quality of meteorological 
models, how to compare them, how to dive into their parametrizations to 
figure out the relevant differences and to solve the problems.

Because we know this, we will be sought after.  However, we will be 
working inside the industry that needs this knowlegde, and outside 
academia or institutionalized weather centres.
