How to make it rain in the DESERT: UAE 解雇する／砲火／射撃s salt ロケット／急騰するs in 試みる／企てる to seed clouds and 誘発する／引き起こす much-needed downpours
- Salt ゆらめくs are 解雇する／砲火／射撃d into clouds over the 砂漠 nation to 誘発する／引き起こす a downpour
- Method is known as cloud seeding and 作品 by 増加するing condensation
- Technique's 有効性 at inducing rain has been called into question
- 中国 used it to 'burst' clouds to make sure it was 乾燥した，日照りの for Beijing Olympics
The 部隊d Arab 首長国s (UAE) is trying to squeeze every last 減少（する） of rain from its clouds by 開始する，打ち上げるing salt ミサイルs into them from 計画（する）s.
The technique is known as cloud seeding, and its 目的 is to 増加する condensation in the hope that it might 誘発する／引き起こす a downpour.?

The country's 国家の Centre of Meteorology and 地震学 (NCMS) is now 試みる／企てるing to tackl the problem by running a cloud seeding programme.

'As soon as they see some convective cloud 形式s, they 開始する，打ち上げる us on a flight to 調査／捜査する,' said 示す Newman, 副 長，指導者 操縦する at NCMS.
Speaking from the airbase that houses the four Beechcraft King 空気／公表する C90 航空機 that are used for the country's cloud seeding programme, Mr Newman said the team would then 試みる／企てる 'to seed the cloud' if the 条件s were 権利.
Mr Newman said summer is usually the busiest season for the 使節団s.
At that time clouds form over the eastern Al-Hajar mountains which deflect the warm 勝利，勝つd blowing from the 湾 of Oman.
The strength of the updraft 決定するs the number of 'salt ゆらめくs' 解雇する／砲火／射撃d as the 計画（する） 調査するs the base of the forming cloud.?
'If we've got a 穏やかな updraft, we usually 燃やす one or two ゆらめくs. If we've got a good updraft, we 燃やす four, いつかs six ゆらめくs into the cloud,' he said.?
Not every cloud they seed produces 降雨, but they often do, によれば Mr Newman.
'It is fantastic... As soon as there is rain, there is a lot of excitement. We can hear the guys in the office are happy,' he said.?
Whether cloud seeding is 効果的な at 増加するing 降雨, however, is still under 調査.
Many scientists 疑問 whether it has a noticable 衝撃 on 降雨 levels.

To cover its 殺到するing water needs, driven by 早い 経済成長 and a 抱擁する influx of 労働者s, the UAE has 訴える手段／行楽地d おもに to desalination - the 過程 of 除去するing salt from sea water to make it usable.
The 湾 country accounts for 14 per cent of the world's desalinated water and is the second largest 生産者 after 隣人ing Saudi Arabia.
The country has 33 desalination 工場／植物s that 供給するd 42 per cent of its needs, によれば a 2013 報告（する）／憶測 by the 環境 and water 省.?
Rain 誘発する／引き起こすd through cloud seeding is much cheaper than desalinated water, によれば Omar al-Yazeedi, 長，率いる of 研究 at NCMS.
In 2010, four days of 強い雨 induced by cloud seeding brought downpours 同等（の） to the nine-year 生産（高） of a 選び出す／独身 desalination 工場／植物 in Abu Dhabi, he said.
'This shows that there is a 抱擁する 量 of water that could be tapped... It is a source that can not be ignored,' he said.

熟考する／考慮するs show that cloud seeding can 増加する the 量 of rain by between five and 70 per cent, depending on the 質 of the clouds, he said.
The American 気象の Society said in 2010 that にもかかわらず some 不確定 over its 有効性, 'large 可能性のある 利益s can 令状 比較して small 投資s to 行為／行う 操作の cloud seeding'.
The UAE is also looking into methods to 保存する the rain that does 攻撃する，衝突する the ground, instead of 許すing it to quickly evaporate or flow off into the sea.
It has built dams and 貯蔵所s to gather water that flood 砂漠 valleys.
The country has around 130 dams and levees with a 貯蔵 capacity of about 120 million 立方（体）の metres (more than four billion 立方（体）の feet), によれば the 省 報告（する）／憶測.
NCMS (n)役員／(a)執行力のある director Abdulla al-Mandoos said 熟考する／考慮するs were 存在 用意が出来ている to 計画（する） more dams and to 保護する water, 目的（とする）d at directing rain 'from the cloud 権利 into the aquifer'.
'We do not want to waste a 減少（する） of water,' he said.
