The Walker circulation forms over the tropical Pacific, where the Western Pacific is typically warm with low sea level pressure and the Eastern Pacific is cooler with high pressure. Warm, moist ...

Some of the climate system’s responses to global warming are rather surprising: Contrary to scientists’ expectations, the Pacific Walker circulation – a large-scale circulation in the tropical ...

Over the past few decades, natural variability has strengthened the Pacific Walker circulation leading to enhanced cooling in the equatorial central-to-eastern Pacific (middle). Climate models ...

March 15, 2025 - By Emily Becker - La Niña conditions persisted through February, but forecasters expect ENSO-neutral conditions to develop in the next month and persist through the Northern ...

(The change was found to be the same for both El Niños and La Niñas.) The descending motion of the Walker Circulation led to suppressed convection and rainfall over the tropical western North ...

The Walker circulation, a tropical atmospheric pattern, has unexpectedly strengthened in recent years due to competing effects of global warming and sea surface temperature (SST) patterns.

The Walker circulation, an atmospheric circulation pattern in the tropics, has accelerated in recent years, puzzling climate scientists who had anticipated the opposite. Researchers from the Max ...
