Zyklone

Im Januar 2002 stürmte einer der stärksten Zyklone der letzten Jahrzehnte über Mauritius. Sein Name war Dina. Mit Windgeschwindigkeiten von über 270 km/h verwüstet ein solcher Sturm ganze Landstriche, zerstört große Teile der Infrastruktur, Landschaften und auch Korallenriffs. Für Touristen sind diese Stürme i.A. nicht bedenklich, da die Hotels recht gut geschützt sind und sich auf die Problematik eingestellt haben. Es kann die Urlaubsfreuden allerdings schon mal um 2-3 Tage verkürzen.

Hier ein paar Satellitenbilder von Zyklon Dina:

Aktuell kann man im Joint Typhoon Warning Center Products (Sturm-Warnungszentrum) die Situation abfragen. Hier werden für den pazifischen und indischen Ozean alle Stürme beobachtet und über die aktuelle Lage berichtet.

REMARKS:

212100Z6 POSITION NEAR 19.4S4 58.0E3.

TROPICAL CYCLONE (TC) 10S (DINA), LOCATED APPROXIMATELY 75 NM NORTHEAST OF PORT LOUIS, HAS TRACKED WESTWARD AT 11 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 211730Z4 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE INTENSITY ESTIMATES OF 115 AND 127 KNOTS. A 211738Z2 SSM/I PASS IS NO LONGER INDICATING CONCENTRIC EYEWALLS WITH 26 NM EYE DIAMETER NOTED IN LATEST INFRARED IMAGERY. THE MID-LEVEL SUBTROPICAL RIDGE

SOUTH OF THE SYSTEM SHOULD INFLUENCE A GENERAL WESTWARD TRACK THROUGH THE NEXT 24 HOURS. AN UPSTREAM TROUGH IS EXPECTED TO WEAKEN THIS RIDGE BY 36 HOURS AND ALLOW FOR TC 10S (DINA) TO BEGIN TRACKING SOUTHWEST THROUGH THE REMAINDER OF THE PERIOD. THE FORECAST IS BASED ON A BLEND OF PERSISTENCE AND AVAILABLE NWP (NOGAPS, AVN, GFDN, UKMET) WHICH ARE ALL IN GOOD AGREEMENT ON THE SOUTHWEST MOTION LATE IN THE FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 211800Z2 IS 40 FEET. NEXT WARNINGS AT 220900Z3 AND 222100Z7.
