Building debris scattered by the storm Katia did not appear again in some coastal areas of England. The storm that occurred on 12 September 2011 is indeed not make the damage worse. But it still begs the question. Understandably, during the last 15 years there has never been as strong storm Katia hit the UK.
Katia follow the same path with another storm. Formed in the warm Atlantic waters off the west coast of Africa, storms that form in this vortex moves toward the Caribbean and the United States where they are back again to the sea.
A small number of storms, including Katia, like a boomerang all the way back across the Atlantic. It usually will be weakened at one point. Storms crossing the Atlantic does not have the same pattern. "The environment the atmosphere trapped in a lock," said a spokesman for the National Hurricane Center, Dennis Feltgen. The storm that formed was trapped and moved quickly to follow the west wind. So, he says, they are flying again. According Feltgen, Katia has shifted from a tropical cyclone into an extra tropical storms, one hurricane is moving and shifting of energy sources.
Based on data from 1851 to 2010, there were only 10 extra-tropical storm in which the tail end of tropical cyclones is the length of 322 kilometers from Ireland. This is demonstrated by the storm Debbie, which hit the British Isles in 1961.
The last time Britain was hit by a strong storm in October 1996, when Hurricane Lili crossed the Atlantic. With wind speeds of up to 90 miles per hour (145 kilometers per hour), the storm killed five British citizens and caused losses of U.S. $ 250 million.
Then the tail of the storm hit the UK and Ireland in 2009, three times in 2006, twice in 2000, and once each in 1996 and 1998. British Meteorological Office said that Katia can be categorized 4 like storm Lili.
Katia's second major storm in the Atlantic hurricane season 2011, another storm is Adrian and Irene, which struck New York and the east coast of the United States last month. In the Pacific Ocean there is a storm of Talas, which hit Japan and East Asia.
A recent study of University of Miami, scientists found no link between El Nino and a major storm. They found that tropical cyclones formed during an El Nino year yield curve that is not dangerous and the storm away from land.
Miami University researchers also found "interesting relation" between the trajectory of hurricanes and climate variability. They studied storms data in the Atlantic Ocean who collected starting 1950 until 2010.
They make the classification of storm tracks in three categories: moving straight, curved back to the land, or curved back into the sea. It turns out the storm that developed further to the south or west of the Atlantic tend to move straight into a storm that ultimately affect the U.S. coast and the western Caribbean.
But the storm that formed over the north or east has a greater chance to bend to the north. This is threatening the east coast of America or curved into the open sea.
The study also found that El Nino-related storms overall frequency less. El Nino is a phenomenon of the warm water pool in the eastern Pacific Ocean.
2009 hurricane season was the most active in the last 12 years. This is evident from the lack of El Nino activity. In that year there are nine tropical storms, three hurricanes and two major hurricanes. In the Atlantic hurricane season produces an average of 11 storms that have names, six hurricanes and two major hurricanes. Data from the 2009 hurricane, tropical storm Claudette could hit the continental United States.
"In a typical El Nino winter, we found data that storms have a higher probability to curve back into the sea and no threat to land along the east coast," said Angela Colbert, one of the University of Miami. This occurs because of changes in circulation across the Atlantic.
According to Colbert, the data is important for weather forecasting. Included also, she said, insurance companies are using it to determine the bid price of each season and annually.
What about La Nina? This is a climatic phenomenon when the surface water in the equatorial Pacific Ocean is cooler than normal temperatures. Last year was an active year in the Atlantic basin, due to the moderate La Nina, which produces 19 named storms, 12 hurricanes, and category 5 storms. But no big storms that hit the mainland United States.
In 2011, the Atlantic hurricane season was in its peak. La Nina is expected came back after not occur during the summer. Until November, many countries in the northern Atlantic and Pacific coast guard to face the next hurricane threat.*** [UWD | OURAMAZINGPLANET | LIVESCIENCE | KORAN TEMPO 3648]
