✦ Synopsis
The end-of-summer snowline (EOSS) on 47 glaciers distributed throughout the Southern Alps of New Zealand is related to changes in Southern Hemisphere atmospheric circulation and sea surface temperature patterns over a 23 year period.
The EOSS provides an index of the glacier mass balance, as high (low) EOSS elevations relative to the steady-state mean equilibrium line altitude (ELA m ) indicate a negative (positive) glacier mass balance. Southern Hemisphere atmospheric circulation and sea surface temperature anomaly maps are produced for the accumulation season (April-October) and ablation season (November-March) for both composite high and low EOSS years.
There is a high correlation between the EOSS for individual glaciers and the mean EOSS for the Southern Alps (EOSS Alps ).
