Large-scale shifting of the weight of the atmosphere between mid- and high latitudes creates climate patterns known as the Arctic and North Atlantic Oscillations. These patterns have a big influence on winter weather in the Eastern U.S.
Weather in the Southeast this fall and winter is keeping up with the dry part of the typical La Niña pattern. Precipitation across most of the Southeast was "below" or "much below" normal for October-December.
Each of the last three decades was warmer than all earlier decades in the instrumental record, and each set a new and statistically significant record, culminating in the 2000s, which was the warmest decade of all.
At the highest point atop the Greenland Ice Sheet, Matthew Shupe and his colleagues are installing a suite of climate and weather instruments. Their goal is to better understand the role of clouds in the rapid warming observed across the Arctic region.
Researchers at NOAA’s National Climatic Data Center collaborate with tropical cyclone centers and scientific agencies around the world to assemble and maintain the International Best Track Archive for Climate Stewardship (IBTrACS), an inventory of tropical cyclones.
