Figure 3
Trends (color fill; units: 10−2 mm s−1 decade−1) and climatologies (contours; units: 10−3 mm s−1) in the derived from the CCMs’ ensemble mean averaged over (a) March-April-May (MAM), (b) June-July-August (JJA), (c) September-October-November (SON), and (d) December-January-February (DJF), over the period 1960–2000. The contour interval for the climatological is 0.2 10−3 mm s−1. Solid and dashed lines represent positive and negative contours, respectively. Stippled regions show the trends significant at the 90% level.
