Study Shows Promise for Subseasonal Forecasts of Heavy Rain in South America

Analysis of Paraguay flooding event during 2015-16 El Niño examines influence of climate at multiple timescales The Paraguay River is an essential lifeblood for the landlocked country that shares it name. It provides Paraguayans with fishing, irrigation for agriculture and access to shipping. But it’s also prone to seasonal flooding, with especially high consequences for […]

New Tutorials for Using Subseasonal Climate Data

A new series of video tutorials, as well as a written walk-through, give step-by-step instructions for accessing, viewing and downloading subseasonal-to-seasonal (S2S) climate data. The tutorials use the International Research Institute for Climate and Society’s Data Library, which hosts S2S data from modeling centers around the world. The written tutorial first appeared in the S2S […]

Experimental Forecasts Could Help Guatemala Recover from Volcanic Eruption

By Sarah Fecht This story originally appeared on the Earth Institute’s State of the Planet blog. La version en español esta disponible aquí.  Guatemala’s Volcán de Fuego erupted in early June, killing at least 110 people, while hundreds more remain missing. Streams of lava and plumes of smoke and ash have displaced thousands of Guatemalans, […]

Andrew Robertson: Bridging the Gap Between Weather and Climate

This story was first posted by Rebecca Fowler for Columbia’s Center for Climate and Life. See the original here. Andrew Robertson is a senior research scientist and head of the Climate Group at Columbia University’s International Research Institute for Climate and Society (IRI). He works on seasonal and sub-seasonal forecasts, with the goal of making […]

IRI@AGU: Improving Long-Range Tropical Cyclone Forecasts

Chia-Ying Lee is an associate research scientist at the International Research Institute for Climate and Society. She studies tropical cyclones, including their structure and the intensity evolution, as well as their prediction at the weather, sub-seasonal scales, and long-term risk assessment. At the annual meeting of the American Geophysical Union next week, Lee will present her work on understanding the factors […]

IRI Data Library Hosts New Experimental Forecasts

Two new extended-range weather forecast databases are now more accessible to public and researchers Wouldn’t it be nice to know now what the weather is going to be for the vacation you have planned next month? Or, if you’re a farmer, whether you’re going to get enough rainfall during a crucial planting time coming up […]

Defining and Predicting Heat Waves in Bangladesh

New research shows that in Bangladesh, heat wave predictability exists from a few days to several weeks in advance, which could save thousands of lives. In the United States, extreme heat events have killed more people in the last 30 years than has any other weather-related phenomenon. In Europe, at least 136,835 people died due […]

New paper highlights applications for subseasonal forecasts

A recent study was the first to comprehensively review the potential applications of subseasonal-to-seasonal (S2S) forecasts, and several affiliates of IRI were co-authors. Andrew Robertson, one of the IRI co-authors, said the paper provides a substantial overview of the progress achieved in S2S — i.e. forecasts issued with two-week to two-month lead times — over the […]

IRI@AGU: Advancing Climate Prediction at New Timescales

Andrew Robertson is a senior research scientist at the International Research Institute for Climate and Society. He heads IRI’s climate group and studies how to improve climate forecasts with lead times between two weeks to two months, referred to by scientists as the subseasonal-to-seasonal (S2S) timescale. He also co-chairs the S2S Prediction Project Steering Group, which […]

S2S Workshop: Summary Blog

Below is an excerpt from a blog post written by Zane Martin for the Initiative for Extreme Weather and Climate. For the full post, see the Initiative’s site. By Zane Martin Last week hundreds of scientists from around the world attended the Workshop on Sub-seasonal to Seasonal Predictability of Extreme Weather and Climate online and at Columbia University’s […]

Event: S2S Extremes Workshop

This week, the International Research Institute for Climate and Society (IRI), the Extreme Weather & Climate Initiative (Extreme Weather), and the WWRP/WCRP Sub-Seasonal to Seasonal Prediction Project will hold a 2-day workshop at the Columbia University Lamont-Doherty Earth Observatory campus in Palisades, New York. Adam Sobel, one of the co-organizers of the event, said that the workshop will bring […]

Q&A: Subseasonal Prediction Project

Andrew Robertson is a senior research scientist at the International Research Institute for Climate and Society, where he also heads the climate group. Much of his research relates to improving climate forecasts with lead times between two weeks to two months, which scientists refer to as the subseasonal-to-seasonal (S2S) timescale. Decision makers in sectors such […]

IRI@AGU: Bridging the Climate-Weather Gap

This post is the last in a series of five Q&As with scientists from the International Research Institute for Climate and Society who will be presenting their work at the annual meeting of the American Geophysical Union in San Francisco December 9 to 13. Not all climate forecasts are created (and researched) equally, something that climate scientists […]
