SPECIAL SESSION
(OPEN TO THE PUBLIC)

THURSDAY, SEPTEMBER 13


PLACE: ICTP MAIN BUILDING LECTURE HALL

TIME: 6:15 PM

Section: 11 - (Theodor T. Fujita session)

Movies and pictures of convective severe weather phenomena

The late Ted Fujita pioneered the use of movies and photographs,  
integrated with other meteorological data (such as radar data, wind and  
thermodynamic measurements, and satellite imagery), in detailed studies  
of severe convective storms and tornadoes. Photogrammetric analysis of  
tornadic debris movies (and videos), and of photographs of tornadoes,  
walls clouds, and other cloud features, has provided estimates of wind  
speeds in tornadoes and elucidated the relationship between convective  
phenomena and their kinematic and thermodynamic structures. In  
addition, the visual documentation of severe convective phenomena has  
led to conceptual models of convective storms that have been used by  
spotters and in observational studies.

In recent years, with the advent of inexpensive consumer digital video  
cameras and an increase in the number of storm chasers in the U. S.,  
many videos and photographs of severe convective phenomena have become  
available for use in case studies. While any selection of spectacular  
videos or photographs is solicited, those in which visual documentation  
is a significant part of a study are particularly encouraged. Videos  
that document tornado behavior or, in time-lapse mode, show the  
evolution of storm structure, are particularly invited.
