The impact of atmospheric moisture transport on winter Arctic warming: Radiation versus latent heat release
Abstract Atmospheric moisture transport (AMT) contributes significantly to the recent accelerated Arctic warming. However, the impact of AMT has not been well quantified, not to mention the relative contribution of its impact on microphysical latent heating (LAH) and longwave radiative heating (LWH)...
