    Composite Moisture Stability Chart a/k/a Lifted Index

    AC 00-45g – change 1, July 29, 2010, Summary of Changes shows that the Lifted Index Chart:

    Section 5.4 was:

    “Removed this section since the Lifted Index (LI) Analysis DIFAX Chart is no longer produced”

    Here is a link to an older pamphlet “The Front”, published by the NWS in July 2003.


    An article on page 6, discusses;

    “A chart that’s applicable to this
    time of year and worth review is the
    lifted index (LI) or composite moisture
    stability chart. This chart has
    been taught to pilots and meteorologists
    for years as a first guess for thunderstorm
    location and intensity.”

    If you can find a copy of the old AC 00-45e, Section 9 discusses the
    Composite Moisture Stability Chart.

    I’d bring a copy of the pamphlet and AC 00-45g to the oral portion of the practical.
