The UAE is evaluating how a man-made mountain could help bring rainfall to the country and is working with the US based National Center for Atmospheric Research (NCAR) according to Arabian Business.
The average annual rainfall in the UAE is less than five inches, often with no rain at all during the summer. Natural mountains help to spur rainfall as moisture-laden winds are forced upwards along the slope, forcing them to cool and condense to form clouds, leading to subsequent rainfall on the windward side of the mountain.
“What we are looking at is basically evaluating the effects on weather through the type of mountain, how high it should be and how the slopes should be,” said Roelof Bruintjes of NCAR. “We will have a report of the first phase this summer as an initial step.” “Building a mountain is not a simple thing,” added Bruintjes. “We are still busy finalizing assimilation, so we are doing a spread of all kinds of heights, widths and locations [as we simultaneously] look at the local climatology.”
