No surprise here: Jet contrails affect surface temperatures

From Penn State High in the sky where the cirrus ice crystal clouds form, jet contrails draw their crisscross patterns. Now researchers have found that these elevated ice cloud trails can influence temperatures on the ground and affect local climate, according to a team of Penn State geographers. Video follows. “Research done regarding September 2001,…

The physics of clouds

From the University of California – Santa Barbara A UCSB physicist’s experimental results disprove long-held ideas about turbulence In 1941, Russian physicist Andrey Kolmogorov developed a theory of turbulence that has served as the basic foundation for our understanding of this important naturally occurring phenomenon. Turbulence occurs when fluid flow is characterized by chaotic physical…
