Average annual rainfall

Description

Snow falls on the peaks in Irian Jaya above a height of 4300 metres, and there are five permanent glaciers or icefields on the highest regions around Puncak Jaya.  All these ice masses, however, are in rapid retreat.  The Meren glacier shrank from 5.6 km2 in 1850 to 1.9 km2 in 1972, and it has been predicted that all the ice fields will disappear within a century.
