Eyewall of Hurricane Key to Predicting Storm’s Intensity Study…

Image on rightg shows two hot towers in hurricane%27s eyewall… By Andrea Thompson — Meteorologists can fairly precisely predict the path a hurricane will take but forecasting its intensity has been much trickier. A new study of the dynamics at the core of the storm has shed light on a process that can change a hurricane’s intensity and the finding could improve storm predictions. The strongest winds of a hurricane occur in the eyewall a ring of clouds that encircle the relatively calm eye at the center of the storm. For several decades meteorologists had observed changes in hurricane intensity associated with the replacement of this main eyewall with secondary eyewalls that formed further out in the storm. But they knew very little about how this replacement mechanism operated. “What has been lacking is a true physical understanding of how this process happens and then that’s where we come in” said study author Robert Houze of the University of Washington. Center of the storm To get a better picture of the energetic ebbs and flows at the center of a storm Houze’s team sent airplanes with radar to take measurements from within Hurricane Rita in 2005.
Ala. town reels from tornado
USA Today – Mar 1, 2007
— A tornado ripped through a high school here Thursday killing at least five people when walls and a roof collapsed on them. There was no word on how many of the victims were youngsters state Emergency Management Agency spokeswoman Yasamie Richardson said. In all tornadoes killed at least seven people in Alabama she said and 35 people were hospitalized for injuries. “The school’s pretty much destroyed” said student Dillon Griggs who was in Enterprise High School when the tornado struck. Griggs said a teacher yelled at students to get down just before the tornado hit after 1 p… “When it stopped people started yelling: ‘Get up! Get up! Get out of here!’ There were kids on the ground crying kids bleeding” he said. Crews used heavy equipment to dig through piles of rubble looking for other victims. The tornado hit the school’s science building according to Larry Walker deputy director of the Coffee County Emergency Management Agency. “We need your prayers” Bob Phares assistant superintendent of city schools said as workers probed the damaged structure. ne person died elsewhere in Enterprise and another person was killed in Wilcox County Richardson said. ne death in Missouri Elsewhere a 7-year-old girl was killed by a tornado in Missouri as thunderstorms stretching from Minnesota to the Gulf Coast spawned violent winds across the central USA. In this town in the southeast corner of Alabama high winds tossed cars and trees and blasted homes.

A hurricane tends to push and lift roofs off of homes while an earthquake rocks a house back and forth. And when it comes to manufacturing a fastener resistant to nature engineers at Stanley Bostich say they’ve nailed it with the HurriQuake Disaster Resistant Fasteners. "With both [hurricanes and earthquakes] there’s a lot of pull through — meaning that the material you’re joining pulls up over the head of the nail. And so that focused our energy on making the head larger" Ed Sutt Stanley Bostitch’s engineer manager of fastening technology tells DBIS. Engineers used geometry to design the oversized head… Engineers say the HurriQuake nail can also be used inside your home and will cut down on squeaky floors and stairs. Independent testing showed that the HurriQuake nail can double a home’s resistance in high winds and provide up to 50 percent more resistance to earthquake-scale forces. It’s also affordable adding only $15 to the cost of building a new house. THE DESIGN: The bottom section of the HurriQuake nail is circled with angled barbs that resist pulling out in wind gusts up to 170 mph. This "ring shank" stops halway up to leave the middle of the nail which endures the most punishment during an earthquake at its maximum thickness and strength.

Active hurricane season risk grows-meteorologists
Reuters AlertNet – Mar 1, 2007
"During a La Nina wind shear tends to lessen" said Thomas Downs meteorologist for Weather 2000. "An El Nino tends to chop the tops off of tropical storms. " Due to the El Nino the 2006 Atlantic hurricane season never came close to matching the record-breaking 2005 season which spawned 28 hurricanes including Katrina and Rita and claimed the lives of hundreds in Louisiana Mississippi and Texas. At one point after Katrina and Rita hit 25 percent of U. refining capacity and a quarter of U… oil production was shut leading to spikes in motor fuel prices. The severity of the hurricane season beginning June 1 will not solely be determined by the absence of an El Nino or the presence of a La Nina. "How severe a season is depends are where the hurricanes go and their intensity" said Jill Hasling president of the Weather Research Center. "If we get another storm into New rleans it’s going to be considered a significant year. " Weather Research Center is predicting an average hurricane season in 2007 with seven named storms she said. Colorado State University’s Philip Klotzbach and William Gray said in December they expect the 2007 season to spawn 14 named storms with seven hurricanes.
