IRI@AGU: Forecast-based Financing for Flash Floods
Forecasts are increasingly used to help reduce the impacts of floods in vulnerable communities. Not all floods are created equal, however. Flash floods are one of the most deadly types on a global scale. While early warning and early action systems for slow-onset floods (from rivers, for example) have improved significantly over the past 50 […]

Video: Managing Water in a Dry Land
The Elqui River valley lies in Chile’s northern, mountainous Coquimbo region, which is extremely dry. The region receives only about 100 millimeters (4 inches) of rain each year, and most of it during one short rainy season. The rainfall is also highly variable and driven in large part on El Niño and La Niña fluctuations. In some years, […]

IRI’s Role in South Africa’s Seasonal Climate Forecast Operations
Several decades of climate research have shown seasonal temperature and rainfall patterns over southern Africa to be predictable months in advance. While scientists recognized the importance of the El Niño Southern Oscillation on seasonal climate variability in this region during the 1980s, South Africa first began issuing regular seasonal forecasts in the early 1990s. Over the past twenty years, enhanced modeling systems have […]
