Oceanic forcing of the wintertime North Atlantic Oscillation and European climate
Article Abstract:
Sea surface temperature (SST) fluctuations are known to be related to the strength of the North Atlantic Oscillation (NAO) in the North Atlantic. A general circulation model of the atmosphere has been used to study the ocean's role in forcing North Atlantic and European climate. The simulations suggest that winter NAO variability can be modeled from a knowledge of North Atlantic SST. It is argued that SST characteristics may be communicated to the atmosphere via evaporation, precipitation and atmospheric-heating processes.

Green-wave phenology
Article Abstract:
A new study shows how the monitoring of climatic variability from 1900 can be extended using green-wave phenology. The research shows that indices measuring the onset of green wave are also measures of climatic variability, although they are rarely used in global ecosystem research. The study analyses green-wave changes in eastern North America between 1900 and 1995 which reveals considerable annual variations, particularly in short-term trends.
