Despite the same shape hodographs (straight line), the VWPs are completely different. One VWP shows uniform westerly flow with height, while the other shows veering winds with height implying warm advection and is more conducive to thunderstorm activity.

Hodograph Shape; In-Depth: Storm Motion and Storm-Relative Winds; Summary; 1. Introduction . 1.1 The Importance of Shear. The hodograph is a graphical tool that helps forecasters evaluate vertical wind shear.

Wind Hodograph A wind hodograph displays the change of wind speed and direction with height (vertical wind shear) in a simple polar diagram. Wind speed and direction are plotted as arrows (vectors) with their tails at the origin and the point in the direction toward which the wind is blowing. This is backward from our station model!!!

Vorticity balance concept for cold pool/shear interaction. If the vorticity of each approaching cold pool is comparable, then vorticity balance upon collision is achieved and air parcel moves …

Mar 29, 2016 · Very generally, meteorologists, forecasters, and storm chasers use hodographs to assess the magnitude of vertical wind shear in the atmosphere, and most importantly, the likelihood of tornadoes based on the forecast alignment of the low-level wind shear vectors relative to the storm motion.

Apr 17, 2024 · Mesoanalysis hodographs give meteorologists a quick, visual way to dissect the atmosphere’s winds. In tandem with environmental data and historical comparisons, they become powerful tools for identifying severe storm potential and …

Jan 12, 2012 · Hodographs are integrally related to a measure of shear known as helicity. We will cover that and bulk shear in the next post. In summary, hodographs are a way of quickly diagnosing the directional and speed shear present in a given setup.

Hodographs demonstrating the relationship between wind shear, wind direction, and storm motion for (A,B) unidirectional and (C,D) curved shear profiles. Heights are in kilometers. Thin solid vector (blue) depict ground-relative wind directions at three heights.

ABSTRACT: Hodographs are valuable sources of pattern recognition in severe convective storm forecasting. Certain shapes are known to discriminate between single cell, multicell, and supercell storm organization. Various derived quanti-ties such as storm-relative helicity (SRH) have been found to predict tornado potential and intensity.
