Artificial Rain in Abu Dhabi

From the UK Daily Mail:

"For centuries people living in the Middle East have dreamed of turning the sandy desert into land fit for growing crops with fresh water on tap.

Now that holy grail is a step closer after scientists employed by the ruler of Abu Dhabi claim to have generated a series of downpours.

Fifty rainstorms were created last year in the state's eastern Al Ain region using technology designed to control the weather.

Most of the storms were at the height of the summer in July and August when there is no rain at all.

People living in Abu Dhabi were baffled by the rainfall which sometimes turned into hail and included gales and lightening.

The Metro System scientists used ionisers to produce negatively charged particles called electrons."

Have scientists discovered how to create downpours in the desert?
