Rainfall experts complete more cloud-seeding trials using jet engines

Scientists have concluded the second phase of a new push towards increasing the amount of rainfall each year in the UAE.

Experts at the National Center of Meteorology were taking part in the UAE Research Programme for Rain Enhancement Science (UAEREP), more commonly known as 'cloud seeding'.

The research looks at the possibility of using a jet engine to artificially form clouds by stimulating local updrafts.

Scientists also looked at how volcanic activity produces rainclouds to explore how similar theories could be applied to cloud seeding.

Experiments were completed at Jebel Jais in Ras Al Khaimah – the UAE's highest peak at 1,934 metres - from December 24, 2021, to January 5, 2022.

Experts conducted 12 tests in different environmental conditions, from clear skies to different kinds of low-level cloud to compare the effects of seeding operations.

The process works via a jet engine composite system that releases a high-velocity stream of aerosol particles into the atmosphere to encourage the development of rain clouds.

“The outcomes of this project have the potential to advance our understanding of cloud formation and precipitation development through contributing new knowledge to rain enhancement science,” said Alya Al Mazroui, UAEREP's director.

“The atmospheric data gathered from this campaign answers many important questions about cloud formation and will help us determine the optimal conditions for our future rain enhancement operations."

The first phase of the project was conducted last year and came after the culmination of three years of theoretical, lab-scale, and numerical modelling work.

On average, the UAE accumulates less than 100 millimetres a year of natural rainfall. The effects of climate change and a growing population mean demand for water will continue to rise.

“We look forward to utilising the findings of such studies to develop more viable and cost-effective cloud-seeding methods that will eventually increase our rainfall rates and enhance freshwater supply," said Ms Al Mazroui.

When Umm Kulthum performed in Abu Dhabi

  

 

 

 

Known as The Lady of Arabic Song, Umm Kulthum performed in Abu Dhabi on November 28, 1971, as part of celebrations for the fifth anniversary of the accession of Sheikh Zayed bin Sultan Al Nahyan as Ruler of Abu Dhabi. A concert hall was constructed for the event on land that is now Al Nahyan Stadium, behind Al Wahda Mall. The audience were treated to many of Kulthum's most well-known songs as part of the sold-out show, including Aghadan Alqak and Enta Omri.

FFP EXPLAINED

What is Financial Fair Play?
Introduced in 2011 by Uefa, European football’s governing body, it demands that clubs live within their means. Chiefly, spend within their income and not make substantial losses.

What the rules dictate? 
The second phase of its implementation limits losses to €30 million (Dh136m) over three seasons. Extra expenditure is permitted for investment in sustainable areas (youth academies, stadium development, etc). Money provided by owners is not viewed as income. Revenue from “related parties” to those owners is assessed by Uefa's “financial control body” to be sure it is a fair value, or in line with market prices.

What are the penalties? 
There are a number of punishments, including fines, a loss of prize money or having to reduce squad size for European competition – as happened to PSG in 2014. There is even the threat of a competition ban, which could in theory lead to PSG’s suspension from the Uefa Champions League.

How the bonus system works

The two riders are among several riders in the UAE to receive the top payment of £10,000 under the Thank You Fund of £16 million (Dh80m), which was announced in conjunction with Deliveroo's £8 billion (Dh40bn) stock market listing earlier this year.

The £10,000 (Dh50,000) payment is made to those riders who have completed the highest number of orders in each market.

There are also riders who will receive payments of £1,000 (Dh5,000) and £500 (Dh2,500).

All riders who have worked with Deliveroo for at least one year and completed 2,000 orders will receive £200 (Dh1,000), the company said when it announced the scheme.

Juliot Vinolia’s checklist for adopting alternate-day fasting

-      Don’t do it more than once in three days

-      Don’t go under 700 calories on fasting days

-      Ensure there is sufficient water intake, as the body can go in dehydration mode

-      Ensure there is enough roughage (fibre) in the food on fasting days as well

-      Do not binge on processed or fatty foods on non-fasting days

-      Complement fasting with plant-based foods, fruits, vegetables, seafood. Cut out processed meats and processed carbohydrates

-      Manage your sleep

-      People with existing gastric or mental health issues should avoid fasting

-      Do not fast for prolonged periods without supervision by a qualified expert

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.

Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.

Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.

Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.

“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.

Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.

From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.

Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.

BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.

Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.

Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.

“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.

Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.

“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.

“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”

The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

What vitamins do we know are beneficial for living in the UAE

Vitamin D: Highly relevant in the UAE due to limited sun exposure; supports bone health, immunity and mood.Vitamin B12: Important for nerve health and energy production, especially for vegetarians, vegans and individuals with absorption issues.Iron: Useful only when deficiency or anaemia is confirmed; helps reduce fatigue and support immunity.Omega-3 (EPA/DHA): Supports heart health and reduces inflammation, especially for those who consume little fish.
