Hurricane
background for kids and experts
Hurricane Strike! is a multimedia package aimed at middle schoolers
that conveys basic concepts of atmospheric science, climate, and geography,
as well as key safety and preparedness skills. The learner is a virtual
house guest of the Castillo family in Fort Walton Beach, Florida. Photos,
sound, animations, and reports from expert Steve Lyons (The Weather
Channel) take the learner through the course of a seven-day hurricane
threat. The package was developed by UCARs Cooperative Program
for Operational Meteorology, Education and Training (COMET) in collaboration
with the Federal Emergency Management Agency, the National Weather Service,
and the American Red Cross.
On COMETs MedEd site, several case studies illustrate the challenges
of hurricane forecasting. Three case studies, each focusing on Tropical
Storm Allison, were created by COMET project scientist William Bua to
train forecasters on the potential shortcomings of high- resolution
numerical models in predicting flooding from tropical storms. Allison
broadsided Houston in June 2001 with up to 900 millimeters (36 inches)
of rainwell above even the amount called for in strongly worded
flood warnings. Among Buas findings: A good storm track
does not necessarily produce a good precipitation forecast. His
study also shows that a fourfold increase in the Eta models horizontal
resolution actually degraded the rainfall forecast for Houston. Bua
found that a comparison of the models predicted precipitation
to its precipitation climatology can help forecasters adjust and improve
their rainfall outlooks.
