Question for Pro Mets about BAM models...

[dwg71]

Are they less reliable removed from the deep tropics or are they just as reliable?

[gkrangers]

Hmm...this appears to be a bas..nevermind.

They are definitely intended as tropical models, but as for the "deep tropics"; I guess that depends on what you define as "deep". I wouldn't consider Irene's current location as "deep" for example, but the BAM models are useful in the situation. Farther north, conditions are usually more dynamic, and global models would theoretically be more reliable.

As a side note, you have three different runs of the BAM suite: shallow, medium, and deep; i.e. you wouldn't heavily you the deep BAM in a situation like Irene, because the circulation is not deep, but is rather very shallow. However, you all have to consider that it would strengthen later yada yada...but that's another story. I think that answers your question.

thank you scott

In this situation they can be used as a second source to the Globals because we are dealing with a situation in the mid-latitudes. They do not do good with the mid-latitudes.

I am not sure about the overall historic performance of those models but as of now in this particular situation the BAM models are doing "alright" perhaps slightly better then alright. Most of the global models had a northward bias with Irene whereas the BAM models kept her further south and she has indeed done such. Just pointing out the obvious not trying to start a flame war.

Now that's nice. Yeah.
