At the moment there is a cyclone off the coast of Queensland, Australia.
Its called Cyclone Yasi - that means it is the 25th cyclone of the season, as cyclones are named alphabetically. In bad seasons the names of cyclones can start again from A-Z if there are very many in the season.
Its the same of Tornado's, Hurricanes etc.
A cyclone is a spinning weather system that brings a lot of rain and high winds with it. It forms over the ocean and moves towards the land causing damage such as uprooted trees, broken windows and damaged roofs.
Here is a link to the news reports on the cyclone is Queensland: Its interesting to see the live coverage of the cyclone and the charts - you can see the cyclone moving in a spinning way, with the satellite image which reworks on temperature.

IN THE NEWS: Gale force winds and driving rain have been battering large parts of Scotland
Read about it on BBC News here
Last night the wind gusts were approx. 65 miles per hour which is 105 kilometers per hour. It was Gale Force 10/11 - on the western coasts and isles.
The Beaufort Wind Force Scale is a standardised measure for describing wind speed.
It is calculated by observing sea conditions.
It consists of a scale of thirteen increments (0 - 12) related to wind conditions that initially affected the sails of the 'Man-of-war' - the main British navy ship, at the time (1800's).
Over time it changed to accomodate storm effects on steam powered ships and land.
Today severe weather warnings given to the public are nearly the same as the Beaufort scale.
The scale is also used in the Shipping Forecasts broadcast on BBC Radio 4 in the United Kingdom.
The Beaufort Scale measures wind speed, wave height, sea / land conditions and has a marker number and a description. You can view it here
Here are a couple of images relating to this post:

Just for interest - Portuguese 'Man of War' Jelly Fish
It looks similar to the sails of the Portuguese fighting ship (Man of war)
