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 […]

­”We need climate information.” – Bangladesh’s agriculture community drives creation of new climate services

A series of three recent training workshops has improved the forecasting capabilities of the Bangladesh Meteorological Department (BMD), while also helping to deepen the relationship between BMD and Bangladesh’s Department of Agriculture Extension (DAE). The activities pave the way for new climate information products developed especially for DAE’s needs, and ultimately to help the farmers […]

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 […]

Climate Variability: What You Need To Know

Climate change is a fairly constant source of news, but this year’s El Niño is bringing more attention than usual to climate variability–changes in climate that unfold on shorter timescales. These are typically natural swings in our climate, be them year-to-year or decade-to-decade. They tend to be more dramatic than the projected average changes anticipated from climate […]

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 […]
