Basically Alligator the different levels that come with that model should all be used in unison really to get a complete picture of the atmosphere. The different levels just give an indication of what the vorticity is like in this region at that level (or height) in the atmosphere.
850 is commonly used for various reasons that vary from how models interpet physics, terrain, boundary layer physics (which is still an active area of research) so 850 is a "safter" bet since the uncertainities are greater 850 and below.. There are sooo many processes going on at the lowest level of the atmosphere that the models can't all pick up on them so a little higher in the atmosphere gives a clearer indication of what is going on, especially since model assimilation in the US for all weather is minute relatively speaking considering it all comes from NOAA.
As for the other parameters they're are practical uses for many of them and some of them help to offer meterologists who know the hardcore physics at work with clues to how these vorticity maximums may evolve with time. Similar to looking at how GFS / NAM vary based upon current conditions, so since we can't look directly at "vorticity data" we look at things that may enhance or impede the development of the area of spinning air (Theta E through thermodynamical processes and zional shear for dynamical processes).
Rainfall is just fun :) I hope this helps. I'm trying to explain this without going into too much detail that would require alot of foreground to understand throughly. I hope I didnt miss anything. |
