Hodograph - A plot representing the vertical distribution of horizontal winds, using polar coordinates.
Hodograph A polar coordinate graph which shows the vertical wind profile of the lowest 7000 meters of the atmosphere.
HODOGRAPH- A graph that shows how the wind speed and direction change with height.
HORIZONTAL VORTICITY- A rotation of air caused by vertical speed or directional wind shear.
Skew-T Hodograph Analysis and Research Program (SHARP): This computer program is used by forecasters to interpret soundings.
Straight-Line Hodograph
The name pretty well describes what it looks like on the hodograph. What causes this shape is a steady increase of winds with height (vertical wind shear). This shape of hodograph favors multicell thunderstorms.

The white line shows the wind vector along that spiral at the current altitude. Meteorologists call these diagrams hodographs and use them as a way to simultaneously observe the wind speed and direction at many altitudes.
