Short summary
Using satellite and comprehensive ground-based observations, we identify pronounced ice-cloud activation associated with transported exogenous aerosols. Under different large-scale atmospheric circulation regimes, ice-phase cloud activated over Mount Qomolangma (MQ) can be efficiently transported downstream through distinct pathways, exerting a pronounced ice crystal seeding effect on cloud–precipitation conversion.
Using satellite and comprehensive ground-based observations, we identify pronounced ice-cloud...
