Increasing rainfall may affect winds: study

(PhysOrg.com) -- Falling raindrops produce friction as they drop through the atmosphere to the ground, and this dissipates the kinetic energy, converting it into diffuse heat. Now researchers in the US have used recently-obtained ...

The pirouette effect in the chaos of turbulence

(PhysOrg.com) -- The quick mixing of coffee and milk after stirring or the formation of raindrops in clouds: these are just two of many phenomena in which turbulent flows play a decisive role. Researchers at the Max Planck ...

Heat conduction is important for droplet dynamics

For driving in the rain, it's preferable that the raindrops roll or bounce off the windshield instead of coating it or even freezing. A team of engineers in the McKelvey School of Engineering at Washington University in St. ...

Armor on butterfly wings protects against heavy rain

An analysis of high-speed raindrops hitting biological surfaces such as feathers, plant leaves and insect wings reveals how these highly water-repelling veneers reduce the water's impact.

Falling faster—researchers confirm super-terminal raindrops

Five years ago, a research team at Michigan Technological University and Universidad Nacional Autanoma de Mexico (National University of Mexico) detected tiny, super-fast raindrops. The finding was unexpected—small drops ...
