  • An Experimental Investigation of Interstitial Air Movement in Seasonal Snow

    Creator:
    Drake, Stephen A.
    Abstract:
    Atmospheric pressure changes do not stop at the permeable snow surface but rather propagate into it. These pressure changes range from high-amplitude, low-frequency events caused by seasonal cycles and synoptic weather systems to small-amplitude, high-frequency events caused by topographic features and turbulence. The effect of pressure changes on interstitial air...

  • Vertical Structure of the Lower Troposphere in a Changing Arctic

    Creator:
    Watkins, Daniel M.
    Abstract:
    The Arctic climate system is changing dramatically as a response to rising atmospheric greenhouse gas concentrations. Key indicators of Arctic change include thinning and retreating of Arctic pack ice, thawing permafrost, greening tundra, and rising surface temperatures. The structure of the atmospheric boundary layer influences and is influenced by processes...
