Hodograph

---

This diagram displays the entire wind profile (shown to the left next to the skewT-logP diagram) as a horizontal plot. Instead of the familiar wind barbs, each wind is plotted as a vector from the origin of the hodograph, and the colored lines connect the end points of the wind observations (kt). The lines connecting the end points of the wind observations represent the vertical wind shear through that layer. The color coded lines show each 3 km deep layer beginning at the surface, as shown to the left in the wind speed versus height plot. Wind directions are plotted on the standard compass headings (e.g., the "south" surface wind at 10 kt in the sample sounding is plotted above the origin (from 180 degrees) at the 10 kt range ring.

Heights above ground level (every 1 km) are marked in black along the hodograph, and the LFC-EL pressure-weighted mean wind is denoted by the brown square. Potential left- (LM) and right-moving (RM) supercell motions (based on the Bunkers technique) are marked by the black circles with cross hairs. The dark cyan lines show the bounds of the effective inflow layer on the hodograph, if present.
