New GFS, How Am I Doing?


Rainshadow

Recommended Posts

I missed by a day comparing it to last April.  Looks like the thread title would have been better named as CAN GGEM, new and improved.  Yes the GFS scored better at 500mb, but did worse at 850mb.  I pulled a couple of new GFS only bias graphs.  Don't ask me why once it became operational the cold bias got worse at 850mb at initialization no less. I guess the good part about the new GFS (at least thru this chart), it's 850mb cold bias (still there) does not get worse with forecast time.

Just make it stop.  No model is going to be totally accurate, but is it too much to make it plausible.  It doesn't paint drip rain here GFS, can't you get it through your I get paid more for every 3hr period I forecast measurable rain head.
