Fig. 2 The relationship between the winter NAO and (a) mean winter surface water temperature at Lough Feeagh, (b) mean winter surface water temperature at Lough Leane, (c) mean winter soil temperature at Belmullet (depth = 50 mm) and (d) mean winter soil temperature at Valentia (depth = 50 mm).
Fig. 3 Time series graphs for mean wind speed (Belmullet) (a) and mean winter surface water temperature (Lough Feeagh) (b) and the winter NAO (1961 – 1997). Winter = December, January and February.
Fig. 4 Mean winter chlorophyll concentrations (g l-1) in Lough Leane plotted against the winter NAO. The data set runs from 1973 to 1992.
