Flash floods are among the world’s deadliest natural disasters with more than 5 000 lives lost annually. Their social, economic and environmental impacts are significant. Accounting for approximately 85% of flooding cases, flash floods also have the highest mortality rate among different classes of flooding, including riverine and coastal. Flash floods differ from river floods in their short time scales and occurrence on small spatial scales, which makes flash flood forecasting a different challenge from large-river flood forecasting.

During the RAV Session (September 1-3, 2021), a special side event explored the needs, the gaps and identified priorities in ocean matters for this unique ‘Oceania’ region. Over 150 participants joined, beginning the conversation about a regional ‘roadmap’ for collaboration on ocean matters. This was timely after the official start of the UN Ocean Decade of Science for Sustainable Development(2021 to 2030) .
The ocean covers over 70% of the planet and produces at least 50% of the planet’s oxygen. It drives our weather and climate, is home to most of earth’s biodiversity and is the main source of protein for more than a billion people around the world. The “blue economy,” which is estimated at US$ 3-6 trillion/year, accounts for more than three quarters of world trade and providing livelihoods for over...
Research meteorologists from Poland (Institute of Geophysics Polish Academy of Sciences, Collegium Civitas), USA (Naval Research Laboratory, Scripps Institution of Oceanography) and Indonesia (Agency for Meteorology, Climatology and Geophysics of the Republic of Indonesia, Andalas University) identified key predictors of floods on Sumatra. The research is part of the Years of the Maritime Continent and the Equatorial Line Observation (ELO) project.
Indonesia takes special precaution of wildfire risk in peatlands areas, and attempt to mitigate the risk by rewetting the peatlands by weather modification activities. The Agency for Meteorology Climatology and Geophysics (BMKG) is working closely with partner authorities in this efforts by providing critical information such as cloud growth potential map from weather forecasts, and real time satellite and radar data analyses to determine flight sorties departure and pinpoint location of cloud cells to be seeded. For this tall order, we had made 16 flight sorties during the period of 13-31 May 2020 that associated with 138,1 mm of rainfall.
The ASEAN Climate Outlook Forum has issued its seasonal forecast for the summer monsoon season, June-July-August 2020 over Southeast Asia, taking into account the possible influence of the El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) on the climate system over the region.
