Tephigram (nonfiction)

Annotated tephigram.

A tephigram is one of four thermodynamic diagrams commonly used in weather analysis and forecasting.

Description

The name evolved from the original name "T-Theta-gram" to describe the axes of temperature (T) and entropy used to create the plot.

Usually, temperature and dew point data from radiosondes are plotted on these diagrams to allow calculations of convective stability or convective available potential energy (CAPE).

Wind barbs are often plotted at the side of a tephigram to indicate the winds at different heights.
