Figure 2 is a drawing showing clouds, the wind, mountains, snow and ice, a river, fields, a forest, houses, a lake, groundwater flow, and the sea. There are volumes in tera cubic metres (1012 m3) against certain items:
atmosphere – 13
snow and ice – 26 000
infiltration – 150
lakes – 230
rivers – 1.7
groundwater flow – 7000
oceans – 1 350 400.
There are upward-pointing arrows indicating loss to atmosphere: evaporation from the lake; transpiration from the forest and fields; evaporation from precipitation (rain); and evaporation from the sea.
There are downward-pointing arrows for precipitation, surface run-off from the mountains and oceanic precipitation.
