Changes in atmospheric latent energy transport into the Arctic: Planetary versus synoptic scales
Abstract Atmospheric meridional energy transport into the Arctic plays an important role in Arctic weather and climate. The transport of latent energy in the form of water vapour strongly influences the Arctic atmosphere. The transport is achieved by circulation mechanisms on various scales and is l...
