Case 017 is the latest in a series of convective cases from different
regions of the United States.This case focuses on the unique aspects
of convective storm initiation and subsequent evolution in ...
This case focuses on the northern California Flood which occurred 31
December 1996 to 3 January 1997. It was a major hydrologic event with
impressive rainfall with subsequent river flooding and levee ...
This case features wide spread aircraft icing over the midwest to the
northeast United States as well as over the northwest United States.

This case spans the tornadic outbreak on Palm Sunday (27 March 1994)
in Alabama. Gravity waves were triggered with deep convection that
developed in northeastern Texas. The waves modulated mesolows ...
A strong winter storm system moved over Southern California and
brought heavy rain as tropical moisture fed into the system. At the
same time, an intense storm system moved across Florida with tornadoes ...
This case covers a storm that is an example of "classical" cyclone
development with some structure similar to the Norwegian conceptual
model of storm development.
For more information, see:
On this day, the combination of abundant moisture, an unusually
intense synoptic scale trough and potentially strong jet dynamics
resulted in the development of tornadic thunderstorms.
For more information, ...
Case 022 focuses on the event that brought severe weather from
Buffalo, NY to Sterling, VA. This case is temporally connected to
COMET Case 018 as it follows the derecho event that moved from
Case 023 follows the development of a strong extratropical cyclone
that took place from 8-11 November 1998. Severe weather that
accompanied the case included blizzard conditions in the Upper Midwest ...
Case 024 follows the formation and rapid intensification of a cyclone
off of the southeastern U.S. coastline. The storm moved almost due
north, affecting nearly the entire eastern seaboard. In retrospect, ...
Case 025 represents one of the most devastating weather events in
Utah's history. On August 11th 1999 a tornado moved through downtown
Salt Lake City between 18:45 and 18:55 UTC. The tornado damage ...
Case 026 follows an early winter storm moving onshore in thePacific
Northwest on November 24, 1999. The storm brought heavy precipitation,
while the associated cold front brought strong winds to the ...
This case is a good example of what happens when the environment is so
capped that despite many other favorable conditions, no convection can
occur. Early in the day, the models and model soundings ...
