According to Chinese myth, rain is water poured out of a dragon; in reality is the Meiyu that dictates rainfall in eastern Asia, producing rain belts jumping from south in spring to north in summer.
Early Sprouting of Leaves Enhances Northern Hemisphere Warming
As leaf out has been advancing 4–5 days per decade, scientists say the effect of vegetation on climate remains poorly understood.
Cleaner Air Takes Some of the Bite out of European Winters
Scientists find that reduced aerosol emissions correspond to fewer extremely cold days.
Extreme Summer Heat over Europe Is Predictable Week-to-Week
Forecasts made one to a few weeks in advance, known as “subseasonal to seasonal” predictions, show more skill in predicting extreme summer heat waves over Europe than spells of normal or cold weather.
New England Winters Are “Losing the Cold”
As extreme cold days wane, the northeastern United States has experienced an increase in mud days.
Yet Again, Warmer Winter Looms for U.S.
NOAA’s winter forecasts are less confident than usual except in Alaska and Hawaii. Expect to see a lot of weather variability in the coming months.
No One-Size-Fits-All Way to Combat Urban Heat Island Effect
Tropical and dry cities respond differently to heat mitigation strategies. This difference should be considered when trying to protect residents from increasingly dangerous summer temperatures.
