Lifted Index charts

[lowlycfi]

Does anyone know where online I can find the NOAA Lifted/K Index charts like the ones shown in AC00-45E? I've looked at the AWC website and can't find it there. Thanks for your help.

Here the national weather service site for the old Black and white LI chart:
http://weather.noaa.gov/fax/miscella.shtml

If you're looking for a more modern version check here:
http://weather.unisys.com/eta/rh.html

If your just looking to learn/teach about LI charts then those should work. However, if your looking for good charts to dertimine TS probability and potential for severity Id use the CAPE/CIN chart. This chart basically measures Pontential Energy throughout all levels in the atmosphere. Heres the site:

Go to the CAPE/CIN link under severe indicies

The CAPE/CIN chart is derived from an even more useful chart here:
http://www.rap.ucar.edu/weather/upper/

This is a Skew T/Log P and a bit more complicated. If you have any questuons feel free to PM me. In addition to TS you can use it to figure out cloud tops, freezing levels, inversions, turbulence etc...

Hope this helps

Perfect DC....that's exactly the one I was looking for. Have a DE around here that likes to ask about it on instrument practical tests. Thanks for the help.
