|Dry: The Arminou Dam
Cypriots have been warned that the island is running dry and that careful conservation of water is now even more important, as it will take two more months before additional sources are available.

The reason for the above average wind and rain is down to the southerly position of our jet stream. These are strong winds in the upper atmosphere, which act like a road steering low pressure systems across the Atlantic to our shores.And is there any particular reason for the jet stream being out of position? Any implications for the global climate system?
Global importanceAnd what happens if the "conveyor belt" shifts position, or even worse, stops its motion?
Climatologists have suggested that the winds, known as the Greenland tip jet, could be a key force in driving the world's climate and the global ocean circulation by pushing cold, dense water to the ocean floor and triggering the thermohaline circulation.
This massive "conveyor belt" carries seawater around the world's oceans. The North Atlantic is a critical point, where warm surface water coming from the tropics on the Gulf Stream is cooled and becomes denser. In doing so, it sinks to the ocean bed and pushes the deep segment of the conveyor belt forward.
Robert Pickart of the Woods Hole Oceanographic Institute in Massachusetts, US, and colleagues have suggested that the exceptional winds at Cape Farewell trigger this overturning (Nature vol 424, p 152).
"They cool and evaporate the surface water making it more salty, and therefore more dense, just south of Greenland," explains Renfrew.
If this is true, then the Cape Farewell winds help drive the Gulf Stream, which keeps Europe warm, despite their high latitude.
