Earth's tropical regions drive some of the most powerful weather and climate variability globally. Among these, the ...

Atmospheric circulation weakens following volcanic eruptions The Pacific Walker Circulation -- and related El Niño and La Niña patterns -- is changing because of human activity, volcanoes in the ...

We analyze the characteristics of atmospheric variations over tropical South America using the pattern recognition framework of weather typing or atmospheric circulation patterns (CPs). During ...

The primary factor was an unusual atmospheric circulation pattern linked to Arctic warming, which accounted for 83% of the cold snap’s intensity.

In the tropics, ocean warming patterns determine rainfall change by driving atmospheric circulation change. In regions of enhanced ocean warming, the atmosphere becomes unstable and conducive to ...

Atmospheric rivers—those long, narrow bands of water vapor in the sky that bring heavy rain and storms to the U.S. West Coast and many other regions—are shifting toward higher latitudes, and ...

Study: Atmospheric circulation weakens following volcanic eruptions The Pacific Walker Circulation — and related El Niño and La Niña patterns — is changing because of human activity ...

Summertime heat waves in the United States tend to be preceded two weeks before by a distinctive atmospheric circulation pattern, climate models suggest. The finding, detailed in this week's issue ...

The tropics have an atmospheric circulation pattern called the Walker Circulation, named after Sir Gilbert Walker, an English physicist in the early 20th century.
