UAE consider to build man-made mountain to increase rain fall

After the extraordinary success of the cloud seeding operations that saw a significant increment of the quantity of rain fell over the United Arab Emirates, it seems that the government is seriously considering the opportunity to build a man made mountain in a bit to improve rainfall.

The United Arab Emirates invested a significant amount of 558,000 USD in the 2015 alone within the Rain Enhancement Program initiative activated by the UAE Ministry of Presidential Affairs (MOPA) and run by the National Center of Meteorology & Seismology (NCMS). As reported by a local newspaper, the  Program provides grants to up to five innovative research and technology proposal over a three year period that are trying to find new ways to enhance rainfall in the Country.

“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. We will have a report of the first phase this summer as an initial step”

Said  National Center for Atmospheric Research (NCAR) scientist and lead researcher Roelof Bruintjes to ArabianBusiness.

He further clarified that the NCAR received funds to provide a detailed modelling study evaluating the effects of building a mountain on the weather.

For those not really specialized in climatology and how the rain process works, humid and warm air moving towards the mountains will be forced by them to raise. While raising the air temperature drops (almost 6.5 Celsius per km for humid air) causing the condensation of the humidity and the creation of rain drops.

In order to do so, the mountain shall intercept the predominant air currents forcing them to release their water content before passing through.

“Building a mountain is not a simple thing. 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. If the project is too expensive, logically the project won’t go through, but this gives them (the Government) an idea of what kind of alternatives there are for the long-term future” Bruintjes said.

“If it goes through, the second phase would be to go to an engineering company and decide whether it is possible or not.”

 We have no other option but to wait the preliminary results.

Record rain in the UAE achieved thanks to clouds seeding

If you are wondering why it rained so much this winter in the UAE, the answer might be more surprising of what you can possibly think. According to updates from the National Center of Meteorology & Seismology (NCMS)’s meteorologist and cloud seeding expert Sufian Farrah, as reported by The National, cloud seeding operations might have played a decisive role in this extraordinarily wet winter.

Annual rainfall in the UAE rarely exceeds 120 millimeters whereas the last 9 March 2016 alone we have witnessed a rainfall of 287 millimeters as reported by ArabianBusiness.

The aim of the 77 cloud seeding missions performed during the first three months of the year was to increase the chance of rain (even though the cloud seeding operation doesn’t necessarily makes it rain) and the quantity of rain falling on the UAE.

This is very important to replenish the water reserves both above ground (dams and channels) and underground,, sustaining the agriculture sector and reducing the overall need of producing sweet water from the sea for daily use.

Basically the clouds are “injected” with salt crystals by mall planes which fly above the clouds. Not all the clouds are targeted since the NCMS cloud seeding programme focuses on mature clouds that have the right configuration to generate rain.

“We covered most of the available clouds in the country, so the rainfall increased. Even if we didn’t carry out any operations it would rain, but the objective of cloud seeding is rain enhancement, and most of the clouds that are subject to seeding will generate rain,” he is quoted saying.

What’s new in Dubai – UAE Hottest News

It has been an “exciting” week in Dubai and the United Arab Emirates, not only for the festivities linked to the end of the Holy Month of Ramadan (the so called Eid Al-Fitr) but also for a series of shocking news that were reported on the most popular newspapers and websites and that I am going to summarize.

We have already discussed about the possibility that the United Arab Emirates might introduce VAT and Corporate Tax in the last Quarter of this year. Needless to say that the residents are following closely the evolution of this issue, since is going to directly affect their future financial status.

Breaking News: UAE to scrap Fuel Subsidies

Fuel Prices to increase

Local newspapers dedicate full coverage to the historical decision – Photo from http://www.gulfnews.com

In addition to that, the Government has recently announced a major and revolutionary change in the fuel subsidies that will be reduced starting the 1st August 2015 in order to have the fuel price to be in line with the worldwide average price. Currently petrol is sold at 1.72 AED per litre (USD 0.47), significantly below the calculated average price of 4.44 AED per litre and current government innervation is calculated to be 1.2 AED per litre for a total of 3.5 Billion USD spent every year.

The Government has established a dedicated committee to monitor the global prices and announce every 28th of the month the price that will be applied at pumps the following month. Analysts have predicted a bearable increase in the petrol price but a slight decrease of the diesel cost.

The decision was “based on in-depth studies that fully demonstrate its long term economic, social and environmental impact. The resolution is in line with the strategic vision of the UAE government in diversifying sources of income, strengthening the economy and increasing its competitiveness in addition to building a strong economy that is not dependent on government subsidies” as stated by Suhail bin Mohammed Faraj Al Mazroui, Minister of Energy and reported by Khaleej Times.

In the long term, this decision will discourage people from buying high-consuming cars and to be more prone to use the excellent public transportation system (Taxi, Metro, Tram, Bus and Monorail in Dubai) with a consequent significant benefit for the environment thanks to the reduced amount of carbon dioxide and pollution released in the atmosphere.

Breaking News: Rain in the Fujairah and Ras Al Khaiman, probably artificially created!

It can sound normal to experience some summer showers to the majority of us. However, here in the desert were drought can last several months, having rain in summer is a out of the ordinary event, especially in the mountainous area that divides the Arabian Gulf from the Indian Ocean.

Some meteorologists say it is normal that the humidity accumulated in the atmosphere as consequence of the very high temperature, can coalesce to form rain drops. In any case, it is unusual and it gained the first page in many news papers and numerous videos and photos were shared on several social media in amazement like the video video from Masafi area @lovestory351 shared on Instagram online.

The good thing is that the downpour had partially filled dams and reservoirs, guaranteeing a discrete water availability for the next months before the coming of the expected winter rains. Usually it rains once in November/December and once or twice in February and this is enough to guarantee the survival of the desert wildlife and to accumulate enough water to reduce the dependency on desalinated water, especially inland.Utilities-me.com has published a calculation that sees that a total of 48 million gallons of water were collected and stored in artificial lakes and dams with the consequent advantages.

However, The National published an article that can explain the unusual downpour: a massive cloud seeding strategy is being implemented in the UAEIn its article, The National report: “As soon as they see some convective cloud formations, they launch us on a flight to investigate,” to try “to seed the cloud”, said Mark Newman, NCMS deputy chief pilot. 

The amount of water that the Emirate of Abu Dhabi could store after having successfully seeded clouds for 4 times in the past years, was comparable to the average desalinated output of 9 year operation of a medium size desalination plant, and it is much cheaper.

Breaking News: UAE promulgated anti-discriminatory Law

We already know that the United Arab Emirates, under the wise leadership of its rulers, is one of the most tolerant Country in the world. In the Emirates hundreds different nationalities find work and a source of income to sustain themselves and their family. Different cultures and religions are living in peace and harmony in this piece of land. In order to maintain this high standards of living and avoiding the spread of any seed of intolerance and hate as terrorist groups like Daesh (so called IS) are trying to do, a most welcomed Law has been recently promulgated.

The new Law was issued against “any form of discrimination on the basis of religion, caste, creed, doctrine, race, colour or ethnic origin following a decree by the President His Highness Sheikh Khalifa bin Zayed Al Nahyan” as reported by Emirates24/7.

The National reported the words of Sheikh Mohammed bin Rashid al Maktoum, Vice President and Ruler of Dubai, who said the law “guarantees the freedom of individuals from religious intolerance … and underpins the UAE’s policy of inclusiveness”.
