A tephigram is a specialized graphical representation used in meteorology to display the temperature and moisture content of the atmosphere at different altitudes. This diagram allows meteorologists to analyze the stability of the atmosphere, as well as to identify potential processes such as convection that may lead to cloud formation and precipitation.

By plotting temperature and dew point against altitude, a tephigram enables meteorologists to visually interpret the relationship between temperature and moisture at various heights, which is crucial for understanding atmospheric phenomena. It provides insights into the vertical structure of the atmosphere, indicating areas of dry air, saturated conditions, and potential instability, which are all vital for weather prediction and analysis.

The other options pertain to different atmospheric elements, such as cloud types, wind patterns, and pressure changes, but do not capture the specific focus of a tephigram on temperature and moisture. Thus, the selection of the option related to temperature and moisture content aligns precisely with the fundamental purpose of a tephigram in meteorological studies.
