Convective Heat Transfer of Spring Meltwater Accelerates Active Layer Phase Change in Tibet Permafrost Areas
The item provides the results of a control experiment about investigating the impacts of convective heat transfer (CHT) on permafrost active layer thermal regime. We applied the Simultaneous Heat and Water (SHAW) model to investigate the impacts of CHT on active layer thermal dynamics on the TGL sit...
