[color=red][b]A sting jet is a meteorological phenomenon which is believed to be the cause of the most damaging winds in European windstorms.
 
Following reanalysis of the Great Storm of 1987, led by Professor Keith Browning at the University of Reading, researchers identified a mesoscale flow where the most damaging winds were shown to be emanating from the evaporating tip of the hooked cloud head on the southern flank of the cyclone. This cloud, hooked like a scorpion's tail, gives the wind region its name the "Sting Jet".[1]
 
It is thought that a zone of strong winds, originating from within the mid-tropospheric cloud head of an explosively deepening depression, are enhanced further as the "jet" descends, drying out and evaporating a clear path through snow and ice particles. The evaporative cooling leading to the air within the jet becoming denser, leading to an acceleration of the downward flow towards the tip of the cloud head when it begins to hook around the cyclone centre. Windspeeds in excess of 80 kn (150 km/h) can be associated with the Sting jet.[2]
 
It has since been reproduced in high-resolution runs with the mesoscale version of the Unified Model. The Sting jet is distinct from the usual strong-wind region associated with the warm conveyor belt and main cold front. There are indications that conditional symmetric instability also plays a role in its formation but the importance of these processes remains to be quantified.[3][4]
 
One storm, Cyclone Tilo (November 6-11, 2007) has also been analysed and found not to display a sting jet, despite displaying strong surface winds and a fractured cold front.[4]

Original Message Giant Wave Impact in Other on Thursday, 17 January, 2013 at 10:39 (10:39 AM) UTC.

Description
Luxury cruise line Silversea has been forced to cancel a cruise onboard the Silver Explorer after the ship was damaged by a giant wave in rough weather while on an 18-night voyage in South America. Media reports claimed four crew suffered minor injuries when a wave struck in the waters between Tierra del Fuego and Antarctica. The cruise line confirmed all 133 passengers and 113 crew were safe, but the damage to the ship was severe enough for Silversea to cut short the cruise and to cancel its next sailing on January 21. The ship has returned to Ushuaia in Argentina, where it departed in early January. It is expected to resume service with a 10-night cruise departing on January 31. [link to hisz.rsoe.hu]
