The moist boundary layer under a mid-latitude weather system

By Ian Boutle, R.J. Beare, Stephen Ernest Belcher, A.R Brown and Robert Stephen Plant

Abstract

Mid-latitude weather systems are key contributors to the transport of atmospheric\ud water vapour, but less is known about the role of the boundary layer in\ud this transport. We expand a conceptual model of dry boundary-layer structure under\ud synoptic systems to include moist processes, using idealised simulations of cyclone\ud waves to investigate the three-way interaction between the boundary layer, atmospheric\ud moisture and large-scale dynamics. Forced by large-scale thermal advection,\ud boundary-layer structures develop over large areas, analogous to the daytime convective\ud boundary layer, the nocturnal stable boundary layer and transitional regimes\ud between these extremes
