  text: The Tibetan plateau (TP) plays an important role in the Asian summer monsoon
    (ASM) dynamics as a heat source during the pre-monsoon and monsoon seasons. A
    significant contribution to the pre-monsoon TP heating comes from the sensible
    heat flux (SHF), which depend on the surface properties. A glaciated surface would
    have a different SHF compared to a non-glaciated surface. Therefore, the TP glaciers
    potentially can also impact the hydrological cycle in the Asian continent by impacting
    the ASM rainfall via its contribution to the total plateau heating. However, there
    is no assessment of this putative link available. Here, we attempt to qualitatively
    study the role of TP glaciers on ASM by analyzing the sensitivity of an atmospheric
    model to the absence of TP glaciers. We find that the absence of the glaciers
    is most felt in climatologically less snowy regions (which are mostly located
    at the south-central boundary of the TP during the pre-monsoon season), which
    leads to positive SHF anomalies. The resulting positive diabatic heating leads
    to rising air in the eastern TP and sinking air in the western TP. This altered
    circulation in turn leads to a positive SHF memory in the western TP, which persists
    until the end of the monsoon season. The impact of SHF anomalies on diabatic heating
    results in a large-scale subsidence over the ASM domain. The net result is a reduced
    seasonal ASM rainfall. Given the relentless warming and the vulnerability of glaciers
    to warming, this is another flag in the ASM variability and change that needs
    further attention.
