This lesson provides a basic understanding of how to plot and interpret hodographs, with application to convective environments. Most of the material previously appeared in the CD lesson, Anticipating Convective Storm Structure and Evolution , developed with Dr. Morris Weisman. Principles of Convection II: Using Hodographs includes a concise summary for quick reference and a final exam to test your knowledge. The lesson comes with audio narration, rich graphics, and a companion print version.

I agree with @vcavaliere, discuss storm types associated with hodograph types.

I believe the scale is wrong on the exercises, answer key is potting 10 m/s segments, but the concentric circles are 20 m/s

Would be nice if you talked more about what kind of storms curved hodographs, straight, etc. represent and why

Nice lesson to learn basics about hodographs with an idea about their connection with storms motion

One improvement that could be made is to put the "determining storm motion" section before the "ground-level vs. storm-relative winds" section.

A bit backwards in instruction -- would be better to explain how to do things first without first discussing the end result and then backtracking to explain how they got that information.

I think this lesson will be very useful as a future meteorologist! I think I could benefit from using hodographs in everyday life.

Never understood Hodograph's until now, I thought it was something extremely complicated but this makes it seem quite simple.

Very good lesson. It is a little technical so a complete study of the lesson is required.

I have to say I struggled with the lessons present as preparation for the quiz. I would respectfully suggest that this lesson may have tried to do a little much a little quickly

Again I feel like it needs to be more of a beginner level. A lot of stuff was briefly explained and I had to turn to the internet for help

Although this is a "Skill 1" module, DO NOT be misled into thinking you will be done in 10 minutes. This is a difficult module so be prepared to put some real time and effort into it and take the quiz more than once. However, the benefit is once you have a working knowledge of how to read it, the information will serve invaluable to you and adds one more tool to your forecasting arsenal especially if you deal with a lot of convective weather situations. It's worth it!!!

I had to do twice with over 2 pages of notes but I am someone with prior training, hard for a level one but it is certainly worth going through if you want to learn how to read a hodograph.

I also retook the quiz several times to get the certificate. I found the module challenging, but interesting and it helped me to understand a great deal about storm structure, prediction, and vertical wind shear. Even with a prior understanding of these factors, I gained more knowledge than I thought from this lesson.

I retook the quiz several times to get the certificate. While doing so, I notice a discrepancy for the true/false question "If the wind changes both direction and speed with increasing height, the resulting hodograph will always be curved." Each time I answered "true", which was sometimes scored as correct, and sometimes scored as incorrect. Aside from this, I rather enjoyed this module.

Chaining vectors on a polar chart is not an intuitive process for most of us. This module had some good interactive drills embedded in the presentation. Would like to have seen at least one more dealing with repositioning the axes to isolate storm motion and storm relative winds.
Terminal Objectives
By the end of this lesson you will be able to plot and use a hodograph to determine wind shear
Enabling Objectives
By the end of this lesson you will be able to do the following:
Given a vertical profile of wind speed and direction, plot a hodograph on a polar coordinate chart
Describe how to use a hodograph to determine the vertical wind shear between two levels
Given a hodograph, determine the total magnitude of vertical wind shear, the mean shear direction, and the mean wind and storm motion from a hodograph
convection, hodograph, vertical wind shear, plotting hodographs, wind shear, hodograph shape, storm motion,
