Overview

Fujita is recognized as the discoverer of downbursts and microbursts and also developed the Fujita scale which differentiates tornado intensity and links tornado damage with wind speed. Downburst damagejpg|thumb|right|300px|Downburst damages in a straight line A microburst is a very localized column of sinking air producing damaging divergent and Straight-line winds at the surface that are similar to but distinguishable from The Fujita scale ( F-Scale) or Fujita-Pearson scale, is a scale for rating Tornado intensity based on the damage tornadoes inflict on human-built structures

Fujita's most well-known contributions were in tornado research—he was often called "Mr. Tornado" by his associates and by the media. [1] Much of what we now know about tornadoes was either discovered or advanced by his efforts. In addition to the Fujita scale, he was a pioneer in the development of tornado overflight and damage survey techniques. He established the value of photometric analysis of tornado pictures and films, to establish wind speeds at various heights at the surface of tornado vortices.

In another major addition to tornado knowledge, he was instrumental in developing the concept of multiple vortex tornadoes, which feature multiple small funnels (suction vortices) rotating within a larger parent cloud. A multiple vortex tornado is a Tornado that contains several vortices rotating around inside of and as part of the main Vortex. His work established that, far from being rare events as was previously believed, most powerful tornadoes were composed of multiple vortices. He also advanced the concept of mini-swirls in intensifying tropical cyclones. The eye is a region of mostly calm Weather found at the center of strong Tropical cyclones The eye of a Storm is a roughly circular area and typically 30–65 km

A master of mesoscale analysis throughout his career, it was his independent development of advanced techniques as a young scientist in Japan which prompted Horace Byers to invite him to the University of Chicago upon overviewing his work. Mesoscale Meteorology is the study of Weather systems smaller than Synoptic scale systems but larger than microscale and Storm-scale cumulus Horace Robert Byers (b March 12, 1906 in Seattle Washington, d The University of Chicago is a Private university located principally in the Hyde Park neighborhood of Chicago. He continued to advance mesoscale meteorology with a keen ability to glean details and synthesize vast information in developing revolutionary theories.
