How do I use the Dvorak Technique?

[year_2005]

Ok I could easily tell the difference between a cat 4-5 and a tropical storm or category 1 by a glance at the sattelite , as would most people who don't have any knowledge about storms. However I am curious about how to make a good estimate of intensity with satellite images via the Dvorak technique. I am shocked about how little information a google search turned up, I saw a slide show in one of the results that gave a good idea of it but it did not give a complete explanation.

Maybe this help:

THE DVORAK TROPICAL CYCLONE INTENSITY ESTIMATION TECHNIQUE - A Satellite-Based Method that Has Endured for over 30 Years

The Dvorak Intensity Analysis Technique (Global Guide to Tropical Cyclone Forecasting:)

Tropical Cyclone Intensity Analysis and Forecasting from Satellite (Original Dvorak paper from 1975)

The Dvorak Technique Through Time (Presentation, webEx required)

Worth noting though that the tecnique isn't exactly meant for amateur forecasters to execute; it's for the trained guys as some discretion is needed, like with the constraints and breaking of them.
