Cleaner ship fuel is reducing lightning in key shipping lanes, research finds

Research from the University of Kansas finds that cuts in sulfur emissions from oceangoing vessels have led to a reduction in lightning stroke density along heavily trafficked shipping routes in the Bay of Bengal and South China Sea. The drop in sulfates from ships can cause fewer cloud condensation nuclei, resulting in weaker convecti...

Damaging thunderstorm winds increasing in central U.S.

New research by the National Center for Atmospheric Research shows a fivefold increase in damaging thunderstorm straight line winds in the central U.S. over the past 40 years, resulting from warmer temperatures and increasing wind speeds. The study used high-resolution computer modeling to estimate changes in winds and found that clima...

SwRI reveals the first 'images' of thunder

Researchers from Southwest Research Institute image thunder for the first time, capturing the sound waves created by artificially triggered lightning. The technique allows scientists to study the origins of thunder and the energetic processes associated with lightning, revealing new insights into this natural phenomenon.

Ancient auditory illusions reflected in prehistoric art?

Researchers propose that ancient cave paintings were inspired by the misinterpretation of sound waves as 'supernatural' echoes. The theory suggests that early humans may have made artwork in response to these echoes, which could have led to the depiction of mythical creatures on cave walls.
