Early indications for Winter 2007/8 (December, January and February)
The North Atlantic Oscillation (NAO) is a phenomenon associated with winter fluctuations in temperatures, rainfall and storminess over much of Europe. When the NAO is in a positive phase westerly winds are stronger or more persistent, northern Europe tends to be warmer and wetter than average and southern Europe colder and drier. When the NAO is in a negative phase westerly winds are weaker or less persistent, northern Europe tends to be colder and drier and southern Europe warmer and wetter than average.
... the predicted winter NAO index for 2007/8 is weakly negative at -0.34 with a standard error of ±1.0. The relatively small amplitude of the predicted index relative to the error bar means there is little associated signal for below- or above-normal European winter temperatures or precipitation. However, the prediction is consistent with a cooler, drier winter over northern Europe as a whole than experienced in winter 2006/7, when the observed index was +1.1.

I know it doesn´t say much, but somehow it keeps me positive about coming winter...
