In the upcoming weekend, the nation is poised to experience additional rainfall, notably in the regions spanning from Fujairah to Sharjah, and Al Ain to Dubai, as conveyed by a senior official from the NCM.
Cloud-seeding endeavors are a routine practice each year, carried out when convective clouds are present. This serves to enhance the precipitation volume. It's crucial to understand that these efforts amplify existing rainfall, rather than generating rain itself," explained Dr. Ahmed Habib of the National Centre of Meteorology.
Between June and August 9, we have successfully executed a total of 22 cloud-seeding operations.
Cloud Seeding: What Is It and How Does It Work?
At the core of cloud seeding lies the technique of augmenting a cloud's ability to generate rain.
Central to this mechanism is the identification of convective clouds, which are especially suitable due to their inherent rain-carrying potential. A specialized aircraft is employed to release salt flares into these clouds, effectively amplifying the rainfall process.
The UAE initiated rain enhancement efforts in the late 1990s, and subsequently, there has been a consistent escalation in the frequency of cloud seeding missions with each passing year.
Weather Forecast: Convective Clouds and Rainfall Anticipated in the UAE
Until Saturday, there's a possibility of convective cloud formation linked with rainfall, according to insights from Habib. Showers of varying intensities could occur, often accompanied by lightning and thunder, particularly in the eastern, southern, internal areas, and the Al Dhafrah region of the country.
Habib, the NCM official, explained, "During this season, our region is influenced by the Indian monsoon, leading to an extension of this effect in our vicinity. This influence can be strong or weak, and last week, it was notably strong."
He continued, "We anticipate similar weather patterns over the upcoming days, especially this weekend, with comparable weather phenomena heading toward the eastern regions."
The region is currently experiencing the effects of something known as the Intertropical Convergence Zone (ITCZ). As temperatures rise during the daytime, the formation of local rainy convective clouds is expected.
Providing insight into the reason for the recent rainstorms in the UAE, Habib clarified, "The country was influenced by the extension of easterly flow that is usually associated with low pressure. This effect was evident both at the surface layer and in the upper layers of the atmosphere. This resulted in a humid air mass originating from the Oman Sea and the Arabian Sea, eventually reaching our region."
"The phenomenon commenced in the eastern part of the UAE and extended into the mountainous areas in the east, interacting with the surface layer. These combined factors triggered the formation of convective clouds in the east and occasionally in the south. These clouds are characterized by strong winds that contribute to intense rainfall, and even the possibility of hail," he elaborated.
