The Dvorak tropical cyclone intensity estimation technique

The history of meteorology has taught us that weather analysis and prediction usually advances by a series of small, progressive studies. Occasionally, however, a special body of work can accelerate this process. When that work pertains to high-impact weather events that can affect large populations, it is especially notable. In this paper we review the contributions by Vernon F. Dvorak, whose innovations using satellite observations of cloud patterns fundamentally enhanced the ability to monitor tropical cyclones on a global scale. We discuss how this original technique has progressed, and the ways in which new spaceborne instruments are being employed to complement Dvorak's original vision. © 2006 American Meteorological Society.
