  • Linking dynamics of the near-surface flow to deeper boundary layer forcing in the nocturnal boundary layer

    Creator:
    Smoot, Alexander R.
    Abstract:
    Weak-wind flow in the nocturnal boundary is one of the most poorly understood problems in the field of meteorology. The understanding of weak-wind flows is essential for the improvement of regulatory dispersion models which are currently rendered invalid under weak-wind conditions and stable stratification. Recently there have been increased efforts...

  • Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

    Creator:
    Thum, Nicolai
    Abstract:
    This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

  • The field edge flux paradox

    Creator:
    Barr, Colleen M.
    Abstract:
    Precision irrigation has made spatially explicit water management a reality. However, detailed knowledge about the spatially variable evapotranspiration is often unavailable. One example location where we can begin to understand the impact of spatial variability on evapotranspiration is at the field edge, which contains a sharp discontinuity in surface conditions....

  • Monitoring and Prediction of Severe Weather Phenomena through GNSS Meteorology

    Creator:
    Tahami, Hoda
    Abstract:
    While primary use of Global Navigation Satellite System (GNSS) is positioning, navigation, and timing (PNT), various GNSS applications have emerged over the past decades that includes GNSS meteorology. GNSS meteorology is the remote sensing of the atmospheric constituents in the neutral atmosphere – mostly in the troposphere - using GNSS...

  • Lasers in the Sky : Distributed Temperature Sensing and a Micro-Meteorological Approach to Quantifying Evapotranspiration

    Creator:
    Predosa, Robert
    Abstract:
    Lower atmospheric flux measurements are a difficult subset of atmospheric data to accurately collect. The interplay of cost, precision, specialty, resolution and repeatability compound an already difficult experimental problem. In response to this, a new, novel instrumentation approach to measuring within the atmospheric boundary layer (ABL) is introduced. The combination...

  • Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

    Creator:
    Johnson, Christopher
    Abstract:
    A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...

  • Vertically integrated sensible-heat budgets for stable nocturnal boundary layers

    Creator:
    Nakamura, Reina and Mahrt, Larry
    Abstract:
    The stable nocturnal boundary layer is commonly viewed or modelled as a balance between the temperature tendency (cooling) and vertical heat-flux divergence. Sometimes the radiative-flux divergence is also included. This perspective has dictated the design of field experiments for investigating stable nocturnal boundary layers. Tower-based micrometeorological data from three field...

  • Make it Rain : A Lagrangian Approach to Investigate Land Surface Controls on Moisture Recycling in the Columbia River Basin

    Creator:
    Tai, Leah Chung-Mei
    Abstract:
    Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...

  • Diurnal and subdiurnal variability in the Mars Pathfinder Presidential meteorology sessions

    Creator:
    Bennett, Scott
    Abstract:
    The Mars Pathfinder (MPF) arrived on the Martian surface on 4 July 1997 to become only the third successful landed mission to Mars, recording surface meteorological data intermittently over a period of 83 Martian days ("sols"). The in situ observations made by the MPF meteorology (MET) experiment were recorded at...
