2014/12/18
A Climate Pattern-Scaling Model (CPSM) that
simulates global patterns of climate change, for a prescribed
emissions scenario, is described. A CPSM works by quantitatively establishing the statistica...

The solar wind is a highly turbulent and intermittent medium at frequencies between 10-4 and 10-1 Hz. Power spectra are used to look at fluctuations in the components of the magnetic field at high fre...
Turbulence:mechanics and structure of anomalous scaling
