They examined the cores for evidence of storm surges—distinctive layers of coarse-grained sands and bits of shell interspersed between the organic-rich silt usually found in lagoon sediments—and pieced together a 5000-year chronology of land-falling hurricanes in the region. In examining the record they found large and dramatic fluctuations in hurricane activity with long stretches of frequent strikes punctuated by lulls that lasted many centuries. The team then compared their new hurricane record with existing paleoclimate data on El Niño the West African monsoon and other global and regional climate influences. They found the number of intense hurricanes (category 3 4 and 5 on the Saffir-Simpson scale) typically increased when El Niño was relatively weak and the West African monsoon was strong. “The processes that govern the formation intensity and track of Atlantic hurricanes are still poorly understood” said Donnelly an associate scientist in the WHI Department of Geology and Geophysics. “Based on this work we now think that there may be some sort of basin-wide ‘on-off switch’ for intense hurricanes. ”Donnelly and his colleagues have pioneered efforts to extend the chronology of hurricane strikes beyond what can be found in historical texts and modern meteorological records and previously applied their methods to the New England and the Mid-Atlantic coasts of the United States… ”Donnelly and his colleagues have pioneered efforts to extend the chronology of hurricane strikes beyond what can be found in historical texts and modern meteorological records and previously applied their methods to the New England and the Mid-Atlantic coasts of the United States. Their research area Laguna Playa Grande is protected and separated from the ocean during all but the most severe tropical storms. However when an intense hurricane strikes the region storm surges carry sand from the ocean beach over the dunes and into Laguna Playa Grande. Such “over-topping” events leave markers in the geological record that can be examined by researchers in sediment core samples. The geological record from Vieques showed that there were periods of more frequent intense hurricanes from 5000 to 3600 years ago from 2500 to 1000 years ago and from 1700 AD to the present. By contrast the island was hit less often from 3600 to 2500 years ago and from 1000 to 300 years ago. To ensure that what they were seeing was not just a change in the direction of hurricanes away from Vieques—that is different storm tracks across the Atlantic and Caribbean—the scientists compared their new records with previous studies from New York and the Gulf Coast.

After ‘06 many remain in a ‘hurricane slumber’ Forecasts call for a volatile season; is the public ready? (27-MAY-07) Sarasota Herald Tribune. scott@heraldtribune. com But that was before the 2006 hurricane season one of the luckiest storm seasons on record when not a single hurricane made landfall in the United S… The state could have a slower and more difficult time recovering from a disaster if people do not prepare they warn. Sales of shutters are down. In some places community meetings on hurricane preparedness are full of empty chairs. Storm talk among neighbors turns to hope for another quiet season not plans for disaster. Some residents know the drill. thers are crossing their fingers hoping for another quiet year. Craig Fugate Florida’s emergency disaster chief calls the state of mind “hurricane slumber.
Mayor quits after tornado
Denver Post – May 27, 2007
- The mayor of this town that was all but destroyed by a tornado this month has resigned saying he needs to focus on his family and isn’t the leader Greensburg needs right now. However the City Council has yet to accept Mayor Lonnie McCollum’s resignation and considers him on sabbatical said council President John Janssen who would replace Mc Collum. The council will take up the issue Wednesday. “He’s submitted his resignation but it’s laying on a table ignored” Janssen said. “We need him to rest up a little bit and it’s our hope to get him back… ” McCollum 62 said he won’t reconsider. He said he resigned because he needs to give more to his family and because he’s not very tolerant of different views of how Greensburg should rebuild something he sees as a roadblock during recovery. McCollum whose home was destroyed by the tornado that ripped through the night of May 4 said he wants to enjoy retirement and not have to attend “meeting after meeting” during the recovery effort. He also acknowledged that he was tired of dealing with complaints. The tornado which was more than 1. 5 miles wide and packed winds of up to 205 mph leveled more than 90 percent of the south-central Kansas town of 1400 and killed 10 residents.
