My cynical self is wondering if the higher end EF4s we've seen in these outbreaks were given their ratings simply for model/forecast verification, and all the other tornadoes are rated with the typical scrutiny. Does anyone know how the analogs pulled with soundings are classified? What is the threshold between the "tornado"(red) and "PDS tornado" (pink) labels?
It's probably pointless conjecture, but I'm still curious.
for the whole tornado , pds tornado hazards , my opinion is ... it would be a useful thing to have if it was modified a bit.
ive seen multiple PDS TOR with nothing ever forming , and the main issue i notice with them events is the K index being under 20.
there is also a capping issue i would like to call it ... no not the cap but as in , sometimes the RH is at 100% and the LCL at 0 meters while having 0 CIN.
only one of these takes into account moister , and its pointless if it can use the others like pds , that has no moister....
its to note that 90% of all famous tornadoes happen in events that had...
MLCIN at -2 to -60
MLLCL at 200 to 1800 Meters
overall RH at 50 to 98%
the image i just posted is the official rules of the hazard list , however the red numbers is what i suggest should be changed , and the black num/letters is what i suggest should be added.
again there is no parameter thread to talk about at this moment.
but the biggest issues with parameters is the whole moister and the whole lack of limiting of parameters (as in overflowing on one parameter that makes the composite parameter seem high just cause one thing is too extreme)
