General Parameter Threads (Composite , Possible Hazard Type, SARS and other parameters)

1. TOI (image 1)
2. STP-700mb pos/neg
3. 700 to 400 DPVA bullseyes
4. NAM discriminator (image 2)
5. Instability axis/euro reflectivity in the warm sector (image 3)
6. euro and nam 850mb jet (50kn+)
7. NAM low level convergence bullseyes in warm sector
8. NAM 700mb jet max in target area

All we have for the TOI is this screenshot, but from what I gathered from the omega project paper, the last three params are the most important

a other thing that bothers me with SHARPPY , is the lack of...
  1. Surface Vorticity
  2. Sfc-1km LR (somehow SHARPPY uses it for Psbl Haz but isn't showing it public)
  3. SFC-0.5km layer for SRH / Shear
heck its impossible to calculate the non supercell tornado parameter since it both needs the 1km LR and surface vorticity.
 
i do know that sharppy is available on github so might be able to make that suggestion on there either in the pull request or discussion also github is a website that can host different types of programming based projects so a word of caution if anyone plans on using stuff there as there could be the possibility for malicious programs on there but not saying thats the case for sharppy at all just would be careful with what you download on there just to let everybody know

i wish there was a way to edit and use Sharppy.

im saying this because i can either use it but unable to edit it.

or edit it but unable to use it....

i can only run it if its a EXE file , when i try to use the whole package thing were i could edit , it wont open .... like nothing happens.... python opens for 0.5 seconds then exits ....

i feel like i could be able to create good things ... however it just wont let me open it unless if its a EXE one file... but i cant edit it if its that....
 
i think it could be its read only or copywrited probably would have to contact the programmer on github plus it might have been designed or programed in a executable format and not python plus i think you have to do a bunch of stuff to get to do a bunch of stuff to be able to access the code but im not sure how to do that
 
So, over on the thread for pyrotornadoes, I came across this post, which I will link in its entirety:

MNTornadoGuy said:
It appears it might be possible to forecast the potential for pyrotornado development. The strongest pyrotornadoes seem to form in an environment with an inverted-V profile, a Haines Index of over 4, high DCAPE values, steep 0-3 km lapse rates, and high values of 10-meter absolute vorticity. I made an experimental index called the Pyrotornado Index or PTI which uses this formula: ((Haines Index+0-3 km Lapse Rates+DCAPE)/1000)+10-m Absolute Vorticity (1E-5 s-1.) The Carr Fire had a value of 20.41, the Creek Fire had a value of 13.3 while the Loyalton Fire had a value of 11.29.

Basically, it's a possible suggestion for pyrotornado forecasting ingredients. I would love to see further research into this in order to see how this can be developed into an actual pyrotornado forecasting parameter and how skillfully it could potentially perform.

would be neat to test it out , however the big problem is the same as the non supercell tornado paramater.

it contains 2 paramaters you cant really check

  1. Haines Index
  2. Absolute Vorticity
would be helpfull if sharrpy would have these parameters.

there is however the
  1. 0-3 km Lapse Rates
  2. DCAPE

able to check and compile a huge list of events

there is this site https://app.chasearchive.com/?q=[YE...fe1be246fa&s=e133e9da621211c7c36d5afe1be246fa
1752625582767.png

however its missing a lot of the paramaters.
however at least it has the 0-0.5 km layer

wish there was a way for some one to contact who made this site to add a few more at least
like
  1. Effectvive Layer - Tornado (super important)
  2. 0-8 km Layer - Tornado
  3. SRW 4-6 km - Tornado
  4. Effective inflow base height - Tornado
  5. LR 0-1 km - Tornado / Landspout (for landspout paramaters)
  6. LowRH - Tornado
  7. MidRH - Tornado
  8. BRN Shear - Tornado
  9. Surface Vorticity - Tornado / Landspout (for landspout paramaters)
  10. Mixing Ratio - Hail / Tornado (for SARS)
  11. 0-9 km Layer - Hail / Tornado (for SARS)
 
2 of the 3 composite parameters i have been developing are now ready.

1: DBRN
similar to BRN but replaces the BWD6 with DCAPE , seems like it will be useful to find the annoying Outflow Forecasted Convective Amplification Deficiency events.

2: CVTP
a corrected VTP , the Formula for this one is found in the link under.
it adds in SRH3 and LOWRH/MIDRH , and caps all the parameters to stop the annoying overflow the VTP has.

once you open it up make a copy of it

try the CVTP out with past events , see how it is compared to the normal VTP and STPC.
 
here is the classic STPC , VTP compared to the CVTP

(what people might not notice is if the 3cape is over 100 , the LR formula instantly goes to 2 , this causes it to have a super large number for no reason)

1753567185801.png
you will notice that all 9 parameters are capped for both min and max.
