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.
Thanks to a groundbreaking new program that relies on advanced satellite technology, a weather index insurance payout of unprecedented scale will benefit poor African farmers.
Researchers from the Earth Institute’s Center for Research on Environmental Decisions will present their work at the 2012 American Geophysical Union Conference in San Francisco this week. Psychology doctoral candidate Katherine Thompson will present a poster entitled “The Psychology of Hazard Risk Perception”; and visiting research scholar Diana Reckien will present a poster entitled “Realities of Weather Extremes on Daily Life in Urban India—How Quantified Impacts Infer Sensible Adaptation Options.”
Jerry Lengoasa, Deputy Secretary General of the World Meteorological Organization — How do we bridge the gap between those who have the knowledge and those who don’t, those who have the capacity and those who don’t have the capacity, and the capability?
What are the odds that this winter will be as snowy as the last two? Climate scientist Jason Smerdon and tree-ring scientist Rosanne D’Arrigo are working on an answer, looking at the long-term history of two important weather patterns—the North Atlantic Oscillation and La Niña state in the tropical Pacific—that similar to last year could collide this winter across the northeast.
