Out of interest what times do the GFS model update on the internet?
And secondly, there appears to be a varying time between the GFS T+0
to T+8 days and T+9 to T+16 days. I say this as the first lot have
recently changed this morning, whereas the second lot haven't, and
they are showing a very mild longer term ~ hence I'm hoping they will
change :-)


Andrew Bond posted in another thread the reason (I think) that there
appears to be a mis-match. Up to T+180, the GFS is run on a finer
resolution (both spatial and temporal); then beyond that, the res. is
course and with lengthier time-steps. I imagine that the post-processing
involved means that effectively you've got two products output, rather
than a seamless stream. I find that they are usually fully updated by
T+5hr, sometimes T+4.5hr.

Some information he but some of it I know is out of date...
