“…Also, from reconstructed SAM indices spanning 53 and 119 years, Yuan and Yonekura (2011) report significant peaks at 16 and 18 years for autumn and at 9 years for summer -both these seasons are considered partially in the JFM time series. The negative association of multi-year rainfall over the eastern parts of southern Africa with glaciation over southern New Zealand (Tyson et al 1997) can therefore also be attributed to this variation in the SH, as a negative correlation between net accumulation of glaciers in that region and the SAM exists (Purdie et al 2011). The correlation between the three time series in the southern African region in Fig.…”

“…The present study shows evidence that this oscillation of anomalies has subsequently persisted until 2012. The glacial advances/accumulation of the Tasmanian Glacier, located relatively close to the Franz Joseph Glacier, has subsequently been shown to have a negative association with the SAM (Purdie et al 2011) while Gillett et al (2006) showed these southern areas of New Zealand to be warmer and drier when the SAM is positive. Indications that the variation in JFM rainfall over the Limpopo River Basin varies on 18-20 year time scale with the SAM will therefore be considered in this paper.…”

“…The connection between large-scale modes of the oceanatmosphere system and mass balance in the Southern Alps has been explored by numerous authors (e.g. Fitzharris et al, 1997Fitzharris et al, , 2007Tyson et al, 1997;Clare et al, 2002;Purdie et al, 2011), revealing the strength and position of the westerly circulation to be a key control. However, correlations between individual climate variables (e.g.…”

“…air temperature and precipitation) and mass balance anomalies do not provide a full explanation of mass balance variability (e.g. Purdie et al, 2011). Further work is needed to explicitly resolve the mechanisms responsible for driving mass balance anomalies through modelling of the surface energy and mass balance of Brewster Glacier over the EOSS period.…”

Reconstructing the mass balance of Brewster Glacier, New Zealand, using MODIS-derived glacier-wide albedo

Abstract. In New Zealand, direct measurements of mass balance are sparse due to the inaccessibility of glaciers in the Southern Alps and the logistical difficulties associated with maintaining a mass balance record. In order to explore the benefit of remotely sensed imaging to monitor mass balance in the Southern Alps, this research assesses the relationship between measurements of glacier surface albedo derived from Moderate Resolution Imaging Spectroradiometer (MODIS) and mass balance observations using the glaciological method on Brewster Glacier over the 2005-2013 period. We confirm that minimum glacier-wide albedo is a reliable predictor for annual mass balance in this maritime environment (R 2 = 0.93). Furthermore, we show that regular monitoring of glacier-wide albedo enables a new metric of winter accumulation to be derived, namely the cumulative winter albedo, which is found to correlate strongly with winter mass balance (R 2 = 0.88), thus enabling the reconstruction of separate winter and summer mass balance records. This allows the mass balance record for Brewster Glacier to be extended back to the start of MODIS observations in 2000 and to confirm that the annual balance of Brewster Glacier is largely controlled by summer balance (R 2 = 92 %). An application of the extended record is proposed whereby the relationship between mass balance and the photographic record of the end-of-summer snowline altitude is assessed. This allowed the annual balance record of Brewster Glacier to be reconstructed over the period 1977-2013, thus providing the longest record of mass balance for a glacier in New Zealand.Over the 37-year period, our results show that Brewster Glacier gained a significant mass of up to 14.5 ± 2.7 m w.e. by 2007. This gain was offset by a marked shift toward negative balances after 2008, yielding a loss of 5.1 ± 1.2 m w.e., or 35 % of the gain accumulated over the previous 30 years. The good correspondence between mass balance of Brewster Glacier and the phase of the Pacific (Inter-)Decadal Oscillation (PDO/IPO), associated with the fast terminus retreat observed between 1978 and 1998, strongly suggests that the observed mass gain of Brewster Glacier since 1977 is only offsetting a longer sequence of dominantly negative balances.

“…It is widely held that the main climatic parameter affecting the behavior of mountain valley glaciers is atmospheric temperature (e.g., Oerlemans, 1997;Anderson et al, 2010;Purdie et al, 2011).
