The book gives e = es - Ap(T-Tw) but I think it's full of poop. haha...completed the whole chart!!! only took 2.5 pages of calculations. Hopefully it's all right but numbers make sense Link to comment Share on other sites More sharing options...
CoastalWx Posted October 23, 2018 Share Posted October 23, 2018 WTF is the GFS doing now? Anybody else noticing lately that it is doing these weird almost gravity wave induced pressure fields affecting srfc winds and precip? That looks unrealistic as modeled. Sure they can happen, but look at the winds and QPF on the 6z GFS. Link to comment Share on other sites More sharing options...

The winds and QPF distribution on the 3 and 6 hr panels shows several upward/downward vertical motion areas that seem exaggerated. Link to comment Share on other sites More sharing options...

Could it be tied with the 700mb VV? Looking at 700mb VV you have almost a similar type of configuration. Or would that be tied into what you were saying with gravity wave induced pressure fields?

You can see some funny looking mesoscale ridges and troughs within the area of low pressure. Just seems bizarre and exaggerated to me. Link to comment Share on other sites More sharing options...

Yeah that does seem rather odd...it's striking too how obvious that is. Great catch though picking that out. Very curious now as to the cause of this within the model. Even tracing this back to when it's off the mid-Atlantic coast there are signs of these features developing but they become more exaggerated as the system progresses northward. Is it possible it's some sort of interaction with the high to the north? But it's almost like whatever is used within the algorithm for SLP/QPF didn't like do any smoothing of the data. I also love how this run pulls the H7 low quite west lol. Lots of funky things this run Link to comment Share on other sites More sharing options...

There's still a time and a place for breaking out the old laptop or desktop in weather.
