New developments in climate research led by atmospheric scientist Yutian Wu are adding to our understanding of the “polar vortex” and other extreme events.

The North Atlantic Oscillation is a key driver of winter weather patterns over the northern hemisphere. In recent years, research has claimed a correlation between the NAO and the 11-year solar cycle. A new paper debunks that claim.
How past climate data improves our understanding of climate change and helps predict its impacts.
Andrew Robertson is creating a forecasting system that will help societies adapt and become more resilient to the impacts of climate change.
Climate scientist Deepti Singh tells the cold truth about the extreme winter weather of the past few weeks.
From crowd-sourcing tornado data to teaching Harlem high-school students about climate change and climate justice, IRI scientists will share a number of fascinating projects at the annual meeting of the American Meteorological Society
Hurricane Patricia, the strongest hurricane ever observed in either the Atlantic or eastern Pacific, is expected to make landfall on the Southwest coast of Mexico this afternoon and evening as an extremely dangerous Category 5 hurricane.
El Niño is earth’s most powerful climate cycle, influencing weather and affecting crops, water supplies and public health globally. What may be the strongest El Niño ever measured is now getting underway, and is already affecting parts of the world.
If you take a look at nearly any satellite image of clouds in the tropics, you’ll notice that the clouds tend to be organized into clusters. One specific type of cloud organization called “self-aggregation.” Self-aggregation is the tendency of tropical clouds to spontaneously clump together, solely due to interactions between the clouds and the surrounding environment.
A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.
