GISS GCM Seasonal Mean Precipiation Bias

GISS GCM Seasonal Mean Precipiation Bias

These products generated using the RA97 canopy stomatal conductance sub-model in (a) DJF (-7.1 to +9.3 mm day-1) and (b) JJA (-8.7 to +15.9 mm day-1), and change due to new conductance sub-model in (c) DJF (-1.4 to +1.5 mm day-1) and (d) JJA (-1.7 to +1.1 mm day-1). Observations over land from New et al. (1999) and over oceans from Huffman and Bolvin (2005). Global means at upper-right corners. Hatched areas are significant at the 95% confidence level for a paired t test. Credit: A.D. Friend, Laboratoire des Sciences du Climat et de l’Environnement; and and N.Y.
