WebMay 13, 2011 · Most pingos in the dataset are located in regions with mean annual ground temperatures between −3 and −11 °C and mean annual air temperatures between −7 and −18 °C. The dataset confirms that surface geology and hydrology are key factors for pingo formation and occurrence. WebSep 1, 2024 · The exposure of unfrozen ground to permafrost is a favorable condition for pingo formation, but upheaval can in some (likely rare) cases be initiated high up in mountain valleys that were exposed to freezing for millennia. The only available example of this case on Svalbard is the Adventdalen Riverbed pingo.
