Stratospheric polar warming by ENSO in winter: A statistical study

[1] Applying Linear Discriminant Analysis on 47 years of NCEP stratospheric temperature data from 1959 to 2005, we find that the warm-ENSO (‘‘El Niño’’) years are significantly warmer also in the stratosphere at the Northern Hemisphere polar and midlatitudes than the cold-ENSO (‘‘La Niña’’) years, during winter. Specifically, the zonal mean, DecemberFebruary mean, 10–50 hPa mean temperature, wh...

Equilibrium in Heavy Ion Collisions

We discuss the question of equilibriation in heavy ion collisions and how it can be addressed in experiment
