May Climate Briefing: El Niño Odds Down Slightly
Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing Since last month’s briefing, weekly sea-surface temperature anomalies have increased slightly to +0.4ºC to +0.5ºC in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region (see first image below). These sea-surface temperatures […]
April Climate Briefing: Models Bullish on El Niño Odds
Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing Since last month’s briefing, weekly sea-surface temperature anomalies have held steady at +0.2ºC to +0.3ºC in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region. While these sea-surface temperatures (SSTs) point to […]
World Met Day: Partnering with national meteorological services to support farmers in Africa
The below is an excerpt from a blog written by IRI staff members James Hansen, Alison Rose and Dannie Dinh and originally appearing on the CCAFS website. On World Meteorological Day, we highlight how CCAFS and partners are supporting national meteorological services in African countries to provide actionable local climate information to farmers. The important contributions […]

Participants were trained to interpret, communicate and guide use of new experimental seasonal forecasts. The training workshop included discussion of new and planned “maproom” products, and planning on the communication and use of the forecast in the four Year-1 pilot districts.
Climate Forecast Methodology
The IRI probabilistic seasonal climate forecast is based on the U.S. National Oceanographic and Atmospheric Administration (NOAA)’s North American Multi-Model Ensemble Project (NMME). It includes the output from the ensemble seasonal prediction systems of NOAA’s National Centers for Environmental Prediction, Environment and Climate Change Canada, NOAA/Geophysical Fluid Dynamics Laboratory, NASA, NCAR and COLA/University of Miami. Ensemble mean seasonal forecast anomaly maps […]
March Climate Briefing: Probability of El Niño Rises
Read our ENSO Essentials & Impacts pages for more about El Niño. Since last month’s briefing, weekly sea-surface temperature anomalies have ranged from -0.2ºC to +0.3ºC in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region. This is firmly in the range of neutral ENSO conditions, although other indicators of ENSO […]
February Climate Briefing: Weak La Niña Replaced With Neutral ENSO, and Uncertainty
Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing Since last month’s briefing, sea-surface temperatures have warmed in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region. Last week, the weekly anomaly for Nino3.4 was +0.1ºC — the first time […]
January Climate Briefing: La Niña on Last Legs
Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing Since last month’s briefing, sea-surface temperature anomalies in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region, have warmed about a tenth of a degree. The past few weeks, these anomalies have been […]
Local beats global when it comes to national climate services in Rwanda
By Dannie Dinh, James Hansen, Floribert Vuguziga, Madeleine Thomson, Yohana Tekeste, and Aisha Owusu This post originally appeared on the web site of the CGIAR Research Program on Climate, Agriculture and Food Security. Climate data gaps are an obstacle to providing useful services for smallholder farmers Climate information—and its use for farming decision making, index-based […]
Mark Cane, George Philander, Win 2017 Vetlesen Prize
Mark Cane was instrumental in the 1996 establishment of Columbia University’s International Research Institute for Climate and Society. By Kevin Krajick, Earth Institute Two scientists who untangled the complex forces that drive El Niño, the world’s most powerful weather cycle, have won the 2017 Vetlesen Prize for achievement in earth sciences. The $250,000 award will […]
