The El Niño and Southern Oscillation (ENSO) is one of the most influential interannual climate phenomena in the global ocean-atmospheric system, with profound impacts on weather patterns, particularly in the Asia-Pacific region.This post was originally […]

The year may have started with a dry spell, but the end of California’s storm season has brought more fresh snow to the Sierra Nevada, pushing the state’s snowpack to 96% of average on April […]

Estimates of carbon dioxide (CO2) emissions from volcanoes may have been significantly underestimated, according to new research by The University of Manchester.This post was originally published on this site

When Hunga Tonga–Hunga Haʻapai, an underwater volcano near Tonga in the South Pacific Ocean, erupted in 2022, scientists expected that it would spew enough water vapor into the stratosphere to push global temperatures past the […]

In a gliding avalanche, the entire snowpack slides down a suitable substratum such as grass or slabs of rock. Such avalanches are always released naturally. This requires the snow on the ground to become moist. […]

Researchers have made a new discovery that changes our understanding of Earth’s early geological history, challenging beliefs about how our continents formed and when plate tectonics began.This post was originally published on this site

People along the densely populated Pacific coasts are exposed to strongly fluctuating rainfall patterns: In East Asia, heavy rain falls in summer, and flooding is already one of the climate risks in this region today. […]

Mountain snowpacks accumulate snow throughout the winter, building up stores of water that will supply communities across the American West throughout the long dry season.This post was originally published on this site

An international team of geoscientists, marine geologists, climatologists, and environmental specialists has found that lingering El Niño events have increased in frequency over the past 7,000 years. In their study published in Nature Geoscience, the […]

A simulation on the origin and evolution of the North Atlantic Oscillation (NAO) has been conducted by a PKU research team led by Nie Ji, Associate Professor of the School of Physics; and Hu Yongyun, […]
