Japan's weather agency looks to improve forecasting with AI
TOKYO, May 17 (Bernama-Kyodo): The Japan Meteorological Agency is considering introducing artificial intelligence (AI) into weather forecasting to improve accuracy by using deep learning, Kyodo news agency reported citing a source close to the matter.
Preparations are underway, with a new team established in April to lead infrastructure and technological development to combine AI predictions based on historical weather data with the numerical forecasting models currently in use.
If implemented, the AI system would use deep learning to analyse vast amounts of data, identifying patterns in weather to generate forecasts for future temperatures and rainfall, among other predictions.
AI-based methods may prove more accurate than current forecasting approaches in certain areas, such as typhoon path prediction.
The agency is expected to announce additional measures to enhance data functionality using AI and other technologies around June.
It currently uses a numerical weather prediction model utilising observational data and supercomputers to simulate future atmospheric conditions. Experienced forecasters then analyze the results, factoring in real-world situations to issue weather reports and disaster
AI has so far been used to fine-tune simulation outputs, and humans will still play an oversight role and issue final forecasts even if AI predictions are introduced.
In addition to weather forecasting, the agency is exploring using deep learning to process observational data from the Himawari-10 weather satellite, set to begin operation in fiscal 2029. - Bernama-Kyodo

MCMC Clarifies Mobile Phone Data Collection Amid Media Reports, Ensures Privacy
KUALA LUMPUR, June 6 (Bernama) -- The Malaysian Communications and Multimedia Commission (MCMC) has clarified its collection of mobile phone data (MPD) from Mobile Network Operators (MNOs), assuring that no Personally Identifiable Information (PII) is accessed, processed, or disclosed. The clarification comes amid recent media reports regarding the matter. In a statement today, MCMC said MPD was used strictly for the generation of official statistics to support evidence-based policymaking in two key domains, namely the ICT Sector and the Tourism Sector. For the ICT Sector, MPD helps produce granular statistics, such as the number of active mobile broadband subscriptions and penetration rates at the state, district, mukim, parliamentary constituency, state legislative assembly (DUN), and local authority levels. For the Tourism Sector, it generates indicators such as the number of visitors and domestic tourism trips. 'The MPD data requested from MNOs is anonymised and contains no PII. 'In addition, MNOs are given the option to either process the MPD data within their own secure environment and submit the required anonymised and aggregated output to MCMC, or, for MNOs without in-house processing capabilities, to submit the anonymised data to MCMC for processing. 'In both cases, no individual subscriber can be identified through the data collected,' it said. MCMC further clarified that the use of MPD as a new source of national statistics was a strategic direction set by the government to strengthen the quality and timeliness of statistical outputs for policy and planning purposes. Implementation of MPD is through collaboration with the International Telecommunication Union (ITU) and the UN Committee of Experts on Big Data and Data Science, it added. Over the past two years, MCMC said extensive engagement with all MNOs had been carried out to ensure mutual understanding of the data requirements, processes, and privacy safeguards.

MADA Ramps Up Support For Padi Farmers Ahead Of Dry Monsoon
GENERAL ALOR SETAR, June 6 (Bernama) -- The Muda Agricultural Development Authority (MADA) is fully prepared for the arrival of the Southwest Monsoon, which is expected to bring dry and hot weather conditions this month, in an effort to ensure the success of the first padi planting season in the Muda Area this year. In a statement today, MADA advised farmers to adhere strictly to the scheduled planting calendar and to expedite padi planting in their fields to maintain a smooth agricultural cycle. 'To address the anticipated water shortage, MADA has intensified the operation of drainage water reuse pumps and booster pumps to increase irrigation supply and speed up water distribution to padi fields. 'MADA is also deploying mobile pumps directly to affected fields to help farmers access water from the existing irrigation network,' the statement read. The agency said it had also held briefings and coordination meetings with field officers and farmers to tackle irrigation challenges, while expanding its agricultural extension efforts to ensure farmers remain aligned with the planting schedule. 'Farmer cooperation is crucial during this dry season to ensure uninterrupted planting activities,' it said. MADA said efficient on-field water management is key to ensuring equitable and sufficient distribution throughout the season. It also encouraged regular field monitoring to reduce the risk of pest and disease outbreaks that could affect crop yields. As of yesterday, water levels at all three of MADA's main dams remain adequate, namely Pedu Dam at 66.34 per cent, Muda Dam at 66.87 per cent, and Ahning Dam at 68.52 per cent. 'These levels indicate that the overall water reserves are sufficient to support irrigation needs for Season 1/2025 in Muda Area,' the statement read.

Aidiladha: Traffic Slow Moving On Major Highways, Getting Heavier On KLK Highway
KUALA LUMPUR, June 6 (Bernama) -- Traffic flow on several major highways was reported to be congested and slow as of 5 pm this evening, following an increase in city folk vehicles leaving to celebrate Aidiladha in their hometowns. A spokesperson for the Malaysian Highway Authority (LLM) said traffic flow on the Kuala Lumpur-Karak Highway (KLK) had increased from the eastbound direction in Gombak to Genting Sempah. On the North-South Expressway (PLUS), traffic on the E2 route was also reported to be slow northbound from Pasir Gudang to Dato' Onn and from Senai Utara to Sedenak, and the same situation was also reported for the southbound route from Universiti Putra Malaysia to Nilai Utara, Nilai to Bandar Ainsdale and Seremban to Pedas Linggi. 'Traffic is also congested on the PLUS Highway, route E1 northbound from Bukit Lanjan to Rawang Selatan, Sungai Buaya to Bukit Beruntung, Bukit Tagar to Lembah Beringin and from Juru to Perai. 'Meanwhile, on the PLUS E1 in the southbound direction, the same situation also occurs from Juru Auto City to the Juru Toll Plaza,' he said when contacted by Bernama today. However, he said that the East Coast Highway (LPT) 1 and 2 are still smooth and under control in both directions. 'However, congestion is reported on the Sungai Besi Highway, therefore a tidal lane has been activated after the Mines Selatan Toll Plaza to UPM/Putrajaya from 4 pm to 8 pm tonight,' he said. -- BERNAMA BERNAMA provides up-to-date authentic and comprehensive news and information which are disseminated via BERNAMA Wires; BERNAMA TV on Astro 502, unifi TV 631 and MYTV 121 channels and BERNAMA Radio on FM93.9 (Klang Valley), FM107.5 (Johor Bahru), FM107.9 (Kota Kinabalu) and FM100.9 (Kuching) frequencies.
