Six Saudi regions targeted for cloud seeding operations
Cloud seeding technology increases the quantity and quality of rainfall by exploiting the characteristics of certain clouds to stimulate and accelerate rainfall in specific and pre-determined areas.
Rain seeding operations in Saudi Arabia are carried out using aircraft designed for the purpose, environmentally friendly materials in specific cloud locations, altering the subtle physical processes within the cloud itself.
It is noteworthy that Saudi Arabia has established a regional cloud seeding program as one of the outcomes of the Middle East Green Summit, announced by Crown Prince and Prime Minister Mohammed bin Salman as part of the objectives of the Kingdom's Vision 2030. The program aims to increase rainfall levels, create new water sources, and increase and intensify vegetation cover to address the challenges related to climate change, desertification, and drought. Operation of the program has begun in the Riyadh, Hail, and Qassim regions, marking the first phase of rain seeding in the Kingdom.
Last year, Saudi Arabia launched programs to localize knowledge, aircraft, and modern technologies, as well as a number of operational projects for the National Cloud Seeding Program. These projects aimed to build and enhance internal capabilities, ensure business sustainability, increase the coverage and efficiency of cloud seeding operations, and reduce aircraft operating costs. They also aim to improve the outputs of the National Cloud Seeding Program to achieve results that align with the Kingdom's Vision 2030 and support the Saudi Green Initiative and the Green Middle East Summit towards a sustainable environmental future.
Executive Director of the Cloud Seeding Program Eng. Ayman Al-Bar recalled the first cloud seeding experiment in Saudi Arabia, which began in 1986, followed by dedicated experiments in the Asir region in 2004 and in the central region in 2006. He noted that the true beginning of the program was in 2022, when it was officially launched in Saudi Arabia, aiming to enhance rainfall and improve water resources.
Eng. Al-Bar explained that the Program's recent cloud seeding operations have totaled approximately 752 flights, totaling 1,879 flight hours, in addition to 51 research flights that lasted approximately 169 flight hours.
He explained that the last rainmaking operation took place in Ramah governorate on Friday, Aug. 8. The operations team monitored weather developments and the results of technical analysis using radar indicated that the clouds were suitable for seeding.
Eng. Al-Bar noted that these flight operations lasted approximately one hour and 20 minutes, while initial results from monitoring techniques indicate a positive change in the cloud's water content. "The research team is currently studying the physical characteristics of the clouds to review the result," he said.
Saudi Arabia is increasingly keen to implement cloud seeding operations to explore new water sources to mitigate drought, prepare natural and environmental resources for adaptation, and enhance environmental performance.
While the country is still experiencing hot summer weather, implementing rainmaking techniques in this climate differs from other seasons of the year due to the nature of the clouds and the prevailing weather conditions. The chances of cold clouds with high ice crystal content are reduced in hot and dry regions.
Eng. Al-Bar emphasized that summer clouds are often warmer, requiring different methods, such as cloud base seeding or cloud top seeding for cold clouds. The Regional Cloud Seeding Program in Saudi Arabia aims to intensify afforestation through cloud seeding, reduce desertification, and train national cadres in this field. Cloud seeding is a promising method that is hoped to be a component of maintaining water balance, as it is a safe, flexible, and inexpensive technology.

Saudi climate center launches project to digitize 73 years of weather records
JEDDAH — The Regional Climate Change Center has launched a project to digitize 73 years of historical climate records, spanning from 1951 to 2023, as part of its efforts to enhance data accuracy, accessibility, and use in scientific research, environmental planning, and data-driven decision-making. Dr. Ayman Ghulam, CEO of the National Center for Meteorology and general supervisor of the Regional Climate Change Center, reviewed progress on the project, which covers data from 33 manned climate stations across Saudi Arabia. The initiative involves digitizing 36,000 historical records with a team of 73 staff, converting paper archives into database-compatible digital copies using the latest scientific and technical standards. The project follows five main tracks: cataloging and assessing paper records, digitizing and entering data, auditing entries for accuracy, conducting climate quality checks with specialized scientific tools, and building human capacity through training programs and technical workshops. Monthly and quarterly progress reports will be compiled, culminating in a final completion report. The climate archives contain data collected using precise monitoring tools and international standards, recorded in both Arabic and English and in metric and occasionally imperial systems. The Center said the project represents a strategic step toward digital transformation in the meteorological sector, supporting environmental security and sustainable development while reinforcing Saudi Arabia's position as a leading regional hub for climate monitoring and forecasting. © Copyright 2022 The Saudi Gazette.

Six Saudi regions targeted for cloud seeding operations
RIYADH — The Saudi Regional Cloud Seeding Program currently aims to implement its operations in six main regions such as Riyadh, Qassim, Hail, Makkah, in addition to Al-Baha and Asir. It is planned to gradually expand its implementation to cover all regions of the Kingdom, based on the nature of climate studies and rainfall distribution. Cloud seeding technology increases the quantity and quality of rainfall by exploiting the characteristics of certain clouds to stimulate and accelerate rainfall in specific and pre-determined areas.

UAE's first undergrad AI class: Only 115 accepted; who are the students?
From over 8,000 applications worldwide, just 115 students have earned their place in the UAE's first-ever undergraduate artificial intelligence program, and their stories truly show what it takes to pioneer the future of technology in the UAE. The Mohamed bin Zayed University of Artificial Intelligence welcomed its inaugural Bachelor of Science cohort this semester with a five per cent acceptance rate. Artificial intelligence has always been a subject to be taught on the master's or PhD level; nevertheless, the groundbreaking undergraduate programme is a one-of-its-kind in the UAE that is specialised in AI and teaches it to its students from day one. In a statement, Provost Professor Baldwin said, 'The jobs of tomorrow are being shaped by AI today and we must ensure that future generations are equipped with the tools and skills to navigate that shift. Our extraordinarily talented students don't just learn about AI, but learn with it, through it, and for it. This is an extraordinary value proposition across all our programmes, but especially for our undergraduate students, who will be studying towards a bachelor's degree in AI that I believe sets a new global benchmark in terms of technical depth, real-world relevance, and the high-end AI job-readiness of the students.' Among the accepted students are Emirati twin sisters Alaa and Aya Mohamed Elsayed, whose journeys into AI took dramatically different paths. Alaa, the youngest winner of the Nasser Bin Hamad Global Youth Creativity Award, has already built AI-driven medical devices for neurological patients and governmental tools for sustainability challenges. "For me, AI isn't just about algorithms — it's about people," Alaa told Khaleej Times. "I feel a huge sense of responsibility. We're not only representing ourselves but also showing how Emirati youth can lead innovation globally." Her twin sister Aya took a creative route to technology. A young journalist personality who has won over tens of awards in poetry, programming, and public speaking, she sees AI as transforming storytelling itself. "I was always the storyteller while Alaa was the builder," Aya told Khaleej Times. "But AI gave me a way to merge creativity with technology. I want to work at the intersection of AI and media imagine tools that help people of determination access culture, or platforms that preserve our oral storytelling traditions." The twins study alongside students like Russian entrepreneur Arthur Leontiev, who left his successful Moscow startup to pursue technical mastery in Abu Dhabi. After leading digital transformation projects for restaurant chains, Arthur realised he needed deeper AI expertise. "I had built a startup and learned a lot from the business world. But I realised I needed depth — real technical mastery," Arthur told Khaleej Times. "The UAE's vision felt like the perfect place to challenge myself." What surprised him the most was the classroom diversity. "I might be sitting next to an Emirati innovator, a student from Asia, and another from Africa. The mix of perspectives is powerful—it's like a live laboratory of ideas." The program offers two streams: AI for Engineering and AI for Business, with students gaining hands-on experience with cutting-edge research, including Arabic language models. Students of the current cohort will be starting their fall classes next week, with the upcoming applications period to be announced soon.
