Module Goal: Teach novice forecasters to effectively use the tephigram. After completing the module, they should be able to read and interpret a sounding plotted on a tephigram and apply that information to aid in the weather forecasting process.
- Given a tephigram, identify and describe the various lines.
- Given a sounding plotted on a tephigram:
- Read or calculate the thermodynamic properties at various levels.
- Determine the convective levels, including the LCL, CCL, LFC, MCL, EL, and MPL.
- Determine stability indices such as LI, SSI, KI, TT, and SWEAT and use them to assess the potential for severe weather.
- Describe how CAPE and CIN are determined.
- List and describe the different types of stability and identify them in a sounding plotted on a tephigram.
- List and describe the different types of lapse rates and relate them to stability.
- List and describe processes that alter stability and give examples of common cases where those processes occur.
- Given a suitable synoptic environment and a sounding plotted on a tephiram, interpret the sounding with regard to common forecast problems.
