GE using Large Eddy Simulation on Sandia’s Red Mesa to lay groundwork for quieter wind turbine blades with better power yield

Green Car Congress

Transition of flow to turbulence on a wind-turbine airfoil; isosurfaces of vorticity from a Large Eddy Simulation (LES). In a 2011 survey of techniques to reduce wind turbine blade noise, Sandia researcher Matthew Barone noted that: There are two primary classes of noise sources on a wind turbine.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

In a new report released by the California Air Resources Board, scientists from the University of California at Davis and Berkeley estimate that rising temperatures from climate change will increase ozone levels in California’s major air basins. Our study reveals that climate change and regional air pollution are intertwined problems.

Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

Arrows denote winds at this level derived from meteorological analysis, showing that the HCN maximum is linked with the upper tropospheric Asian monsoon anticyclone. Satellite records from 2004 to 2009 showed a pattern of increases in the chemical’s presence in the stratosphere each summer, correlating with the timing of the monsoon.
