Through June, the eastern Pacific was warmer than average, but the lack of a strong gradient in sea surface temperature anomalies between the eastern and western Pacific may have kept the atmosphere from getting in sync with the developing El Niño.
A pool of warm water lurking beneath the surface of the western Pacific has been slowly sloshing eastward in the past few months. This traveling wave of warm water is one of the signs that climate conditions are favorable for the emergence of El Niño later this year.
If you are someone who wants more or stronger ENSO events in the future, I have great news for you–research supports that. If you are someone who wants fewer or weaker ENSO events in the future, don’t worry–research supports that too.
How do changes in the equatorial Pacific Ocean impact places much farther away? The answer for the tropics, at least, lies in changes to the equator-wide atmospheric circulation called the Walker Circulation.
We’d like our forecasts—both weather and climate—to be simple and certain. Because of the fluid and chaotic nature of the ocean and atmosphere, however, forecasts are never about certainty: they’re about probability.
An open-source suite of tools developed specifically for farmers and ranchers in the southeastern U.S. Tools available can help growers plan for certain types of crop disease, crop yields, climate and drought risks, growing degree days, greenhouse gas emissions, and water usage.
