A powerful storm system unleashed record-breaking rainfall across the United Arab Emirates (UAE) and Oman this week, causing widespread flooding, disrupting travel, and tragically claiming lives.
In Oman, the deluge resulted in at least 20 deaths, while one person perished in the UAE, where government offices and schools closed for days due to the extensive flooding.
Unprecedented Rainfall in Al Ain
The UAE’s Al Ain recorded a staggering 254 millimeters (10 inches) of rain in 24 hours, the highest amount since records began in 1949. This extreme weather event overwhelmed the region’s infrastructure, turning highways into rivers and inundating homes.
Could Cloud Seeding Be to Blame?
Given the UAE’s frequent use of cloud seeding, a process that enhances rainfall, some questioned whether it could have triggered the storm. However, the UAE’s meteorological agency confirmed that no cloud seeding operations occurred before the storm’s arrival.
Climate Change as the Culprit
Experts instead point to climate change as the likely culprit behind the extraordinary rainfall. A combination of low pressure systems, intensified by the contrast between warm ground temperatures and cooler upper-level temperatures, created ideal conditions for a powerful thunderstorm.
Climate change has increased global temperatures, leading to more extreme weather events worldwide, including intensified rainfall. Warmer air holds more moisture, contributing to heavier downpours like those experienced in the UAE and Oman.
The Role of Warmer Seas and Atmosphere
Experts like Mark Howden, Director at the Australian National University’s Institute for Climate, Energy & Disaster Solutions, highlight the role of “extraordinarily” warm water in the seas surrounding Dubai and the warmer air above. This combination increases evaporation rates and the atmosphere’s capacity to hold moisture, resulting in heavier rainfall.
Extreme Rainfall Expected to Worsen
Climate scientists warn that extreme rainfall events like those in the UAE and Oman are likely to worsen due to climate change. The increased moisture in warmer air means that when conditions are favorable for heavy rain, the downpours will be even more intense.
The recent floods underscore the urgent need for global action to address climate change and mitigate its devastating impacts. As extreme weather events become more frequent and severe, countries like the UAE and Oman must invest in resilient infrastructure and disaster preparedness measures to protect lives and livelihoods.
