Forecasters could give India weeks of advance warning before moist heatwaves strike

The progressive rise in temperatures poses a growing threat to the staging of summer sporting events in Europe and, more specifically, to the Tour de France, due to the increasing risk of heat stress for athletes. This is one of the conclusions of a study published in Scientific Reports, which analysed climate data associated with more than 50 editions of the French race.

A new study reveals that heat uptake fluctuations in the Aegean Sea during August provide a powerful new tool for predicting Eastern Mediterranean winter rainfall. Researchers developed the Aegean Sea Heat Uptake Anomaly (AQA) index, showing that when the sea releases more heat in late summer, the following winter tends to bring more frequent and persistent “Cyprus Low” storm systems across the Eastern Mediterranean. The regional index captures a substantial share of year-to-year rainfall variability and significantly improves seasonal forecasting skill compared to traditional global climate indicators such as ENSO and the North Atlantic Oscillation (NAO). By identifying a localized ocean signal with strong predictive power, the study marks a major advance in Mediterranean seasonal rainfall forecasting.

For the first time, researchers have observed and measured weak electrical discharges, known as coronae, on trees during thunderstorms, according to a new study published in AGU's journal, Geophysical Research Letters.

A new study from researchers at MIT identifies the impact of major wildfires and volcanic eruptions on global atmospheric temperatures, and underscores the importance of human activities in causing tropospheric warming.
