Question from me....

[hurricanetrack]

Why is it that the GFDL output is not made available to the public for so many hours after it presumably comes out?

You know, the 00Z hurricane models show up on the various servers at around 8:30-8:50pm EDT. Why not the 00Z GFDL too? What's up with that. Been wondering that for a long time.

Maybe the GFDL takes longer to run, like the global models?

The tropical models don't require much computing, so they run quick and are released just after their run time.

Just a guess.

GFDL is computationally intensive relative to the BAMs and LBAR.

The other thing that may delay its release is the fact that it relies upon the GFS for initial and boundary conditions. If it uses true 00Z initial conditions (and not the 6 hr forecast from the 18Z GFS), then those aren't available until 0330Z. I don't know for sure if that is the case, however.

I would not think that the 00Z GFDL would use the 6 hour forecast from the 18Z GFS for initialization.
