Atlantische Hurrikansaison 2009

    Die Atlantische Hurrikansaison 2009 beginnt offiziell am 1. Juni und endet am 30. November. Innerhalb dieser Periode bilden sich die meisten tropischen Stürme, da nur zu dieser Zeit geeignete Bedingungen, wie etwa ein warmer Ozean, feuchte Luft und wenig Windscherung, existieren, um die Bildung von Tropischen Wirbelstürmen zu ermöglichen.


    In der atlantischen Hurrikansaison 2009 werden die folgenden Namen verwendet. Diese Liste wird im Jahre 2015 wieder verwendet, vorbehaltlich der Namen, die durch die World Meteorological Organization im Frühjahr 2010 möglicherweise ersetzt werden. Diese Liste ist identisch mit der Liste für die Atlantische Hurrikansaison 2003, mit Ausnahme der Namen Fred, Ida und Joaquin, die Fabian, Isabel und Juan ersetzt haben.

    Prognosen vor Beginn der Saison


    Am 10. Dezember 2008 sagte Klotzbachs Team in einer ersten Prognose für die atlantische Hurrikansaison 2008 eine überdurchschnittliche Aktivität mit 14 benannten Stürmen voraus. Von dem Team wird erwartet, dass davon 7 Stürme zu einem Hurrikan werden, wobei drei von ihnen zumindest die Kategorie 3 erreichen.

    Hallo Freunde hier ist die neueste Vorsage fuer die kommende "Hurricane Season"
    Atlantic hurricane forecast lowered
    University team now expects 6 between June and November

    MIAMI - The Colorado State University hurricane research team on Tuesday lowered its 2009 Atlantic season forecast, predicting 12 tropical storms would form and six would become hurricanes.


    The noted research team founded by storm forecasting pioneer William Gray said the six-month season beginning on June 1 could see the development of a weak El Nino, the warm water phenomenon in the eastern Pacific Ocean that tends to diminish Atlantic hurricane activity.


    In its previous forecast in December, the CSU team predicted 14 storms and seven hurricanes in the 2009 season.


    The researchers said they had seen cooler sea surface temperatures in the tropical Atlantic Ocean in the last few months. Hurricanes draw energy from warm sea water.


    "We expect current weak La Nina conditions to transition to neutral and perhaps weak El Nino conditions by this year's hurricane season," Gray said in a statement.


    "If El Nino conditions develop for this year's hurricane season, it would tend to increase levels of vertical wind shear and decrease levels of Atlantic hurricane activity," he said.


    The team said two of the six hurricanes were expected to be "major" storms of Category 3 or higher on the five-step Saffir-Simpson scale with sustained winds of more than 110 miles per hour.


    The 2008 Atlantic season was one of the busiest on record, with 16 tropical storms, of which eight became hurricanes with sustained winds of 74 mph or higher, and five were of Category 3 or higher.


    Cuba got the worst of last season's destruction. Three major hurricanes hit the Caribbean island, destroying or damaging nearly half a million homes, flattening sugar cane and tobacco fields and causing an estimated $10 billion damage.


    The long-term average for the Atlantic hurricane season is about 10 tropical storms and six hurricanes. But experts said a period of heightened Atlantic hurricane activity started around 1995 and was expected to last 25 to 40 years.



    While disaster management experts say forecasts like the one issued by Colorado State help raise public awareness, many note that it is an inexact science. Some forecasters, including the Colorado State team, have been well off in recent years.


    Last month, U.S. forecaster AccuWeather said the 2009 season would produce 13 tropical storms, of which eight would become hurricanes and two would be Category 3 or higher.


    London-based Tropical Storm Risk on Monday issued a forecast of 15 tropical storms, 7.8 hurricanes and 3.6 major hurricanes.
