Abstract
The links between climate and glacier change are investigated by examining the relationships between atmospheric circulation and glacier balance changes over a 17 year period. Altitudes of the end-of-summer snowlines made on some 48 index glaciers provide surrogates for mass balance, and mean atmospheric pressure maps were computer-generated for the south-west Pacific from long-period meteorological station data. Pressure data are separated into accumulation and ablation seasons. The results show that atmospheric circulation patterns exert a strong control on glacier mass balance, with positive balances associated with anomalous south to south-west flow and negative balances associated with enhanced north to north-east flow. ©1997 by the Royal Meteorological Society.
