  1. Looking at the basic GFS chart viewer and in particular the 3hr PPN output. I've noticed that areas of ppn grow and shrink in intensity for each 3 hour step. eg. low intensity at 0z, high intensity at 3z, low intensity at 6z, ... and so on.

    Could anyone tell me whats going on? Cheers.

    Hi ICBINT

    PPN can alter dramatically in a very short space of time whether it is frontal or convective due to many reasons.

    The comment I really want to make is that on a thread for newbies (see 1st post) they may not understand acronyms like GFS, PPN, Oz etc .... did you when you first came on site.

    Not to say your observation is not valid.

    Regards.
