Hodograph

A plot representing the vertical distribution of horizontal winds, using polar coordinates. A hodograph isobtained by plotting the end points of the wind vectors at various altitudes, and connecting these points in order of increasing height. Interpretation of a hodograph can help in forecasting the subsequent evolution of thunderstorms (e.g., squall line vs. supercells , splitting vs non splitting storms , tornadic vs. nontornadic storms , etc.).
