Warmer — but when?

Monday, 22 April 2013 | Weather

Have a look at this page — the 3-month outlook from the Climate Prediction Center.

You can click into maps for a rough-sketch prediction of both temperature and precipitation anomalies for any 3-month period stretching forward over the coming year and a quarter. This tells you the probability of it being either warmer or colder, wetter or drier, than usual — not a terribly strong or reliable indicator necessarily – but of use to the idly curious, and especially to farmers and orchardists who need to bank on general weather trends relatively far in the future.

The “Prognostic Discussion” link provides the latest meteorological thinking over the coming 90 days, and tells you what longer term factors (atmospheric phenomena like the Madden Julian Oscillation or El Nino/La Nina (“Enso”) cycles, and geophysical factors like sea-surface temperatures and soil-moisture) figure into the prediction.
