January Climate Briefing: La Niña Eyes Spring Departure

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-January, the tropical Pacific sea-surface temperatures were well below average and into the moderate strength La Niña range. All atmospheric parameters also indicated La Niña conditions. A new set of model runs predicts La Niña conditions are likely to dissipate by May-June 2021, with […]

December Climate Briefing: La Niña Shows Signs of Receding

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-December, the tropical Pacific sea-surface temperatures were well below average and into the moderate strength La Niña range. All atmospheric parameters also indicated La Niña conditions. A new set of model runs predicts moderate or possibly strong La Niña conditions through 2020, approaching a […]

November Climate Briefing: La Niña Staying for the Holidays

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-November, the tropical Pacific sea-surface temperatures were well below average and into the moderate strength La Niña range. All atmospheric parameters also indicated La Niña conditions. A new set of model runs predicts moderate or possibly strong La Niña conditions through 2020, approaching a […]

ENACTS Climate Services Initiative Ripples Across East Africa with WISER Support

Somalia, South Sudan and a number of other East African countries are now developing their own powerful climate analysis and visualization tools for decision making, using the Enhancing National Climate Services (ENACTS) approach. These efforts were made possible through a partnership with the Kenya-based IGAD Climate Prediction and Application Center (ICPAC) and with funding from […]

October Climate Briefing: La Niña Comes Knocking

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-October, the tropical Pacific sea-surface temperatures were well below average and into the moderate strength La Niña range. All atmospheric parameters also indicated La Niña conditions. A new set of model runs predicts moderate or possibly strong La Niña conditions through 2020 and most […]

New data and tools bring a deeper understanding of El Niño

Updated maps document expected impacts of ENSO conditions for decision makers across the globe. In 2001, the International Research Institute for Climate and Society’s Simon Mason and Lisa Goddard published an important analysis of how El Niño and La Niña events historically have influenced rainfall around the world. Out of that analysis they produced a […]

Student Spotlight: Finding ways for climate services to improve nutrition in Vietnam

By Joseph Conway During the summer of 2019, Pranav Singh, a graduate student at Columbia University’s School of International and Public Affairs, interned in Hanoi, Vietnam for the Adapting Agriculture to Climate Today, for Tomorrow (ACToday) Columbia World Project. Singh’s work focused on understanding where climate services–weather forecasts, early-warning systems, climate predictions and other resources–could […]

September Climate Briefing: La Niña Eminent

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-September, the tropical Pacific sea surface temperatures were below average and into the weak/moderate La Niña range. Most atmospheric indicators also suggested La Niña conditions. A new set of model runs predicts likely weak or moderate La Nina through fall and most of winter, […]
