Figure 59. Winter snow accumulation, bw, from benchmark glaciers (averaged for all available observations; see Dyurgerov, 2002), and annual precipitation, <Pa>, averaged for Northern Hemisphere latitude 40° to 60°, at two altitudinal ranges, 0 to 500 m and 2,000 to 2,500 m. From the Global Historical Network Climatology database. The apparent trend from 1960 to 2000 indicates winter snow accumulation sharply increasing from 1998 to 2000.
