Solomon, A., 2006: The impact of latent heat release on polar climate. Geophys. Res. Lett., 22, L07716.


In this study we use model output from a range of coupled climate models, as well as, focused AGCM experiments to support the hypothesis that in a warmer climate increased moisture availability will cause a warming of the Polar Regions through increased dynamical heat transports. Projections of climate change due to increased greenhouse gases predict significant warming of the Polar Regions. This change in polar temperatures has been primarily attributed to ice-albedo feedbacks. However, in this study we show that in our AGCM experiments the temporal and spatial coherence between developing extratropical cyclones and latent heat release causes a greater than 2°C warming of the poles.
