Improved techniques for evaluating GCM cloudiness applied to the NCAR CCM3
Evaluations of GCM cloudiness typically compare climatological output with observations, but averaging over time can obscure the presence of compensating errors. A more...- publication PDF

Nonlinear controls on the persistence of La Niña
A large fraction (35%-50%) of observed La Niña events last two years or longer, in contrast to the great majority of El Niño events, which last one year. Here, the authors...- publication PDF
