Precipitation‐driven glacier changes in the Pamir and Hindu Kush mountains

Glaciers in the Pamir and Hindu Kush mountains, unlike those elsewhere, have shown slight mass gains rather than losses due to global warming. A study using laser altimetry and satellite-derived precipitation data revealed a strong correlation (r ≥ 0.92, p < 0.005) between annual glacier thickness changes and precipitation from 2003 to 2008, highlighting precipitation as the primary driver of these changes. However, gridded precipitation products significantly underestimate actual precipitation by about 7 ± 2 times due to low resolution and failure to account for orographic effects. This underestimation may introduce biases in previous glacier mass change estimates, suggesting that long-term interannual precipitation variability plays a crucial role in glacier dynamics.
