Mountain Snowpack Hydrology

世界各地的山区都是重要的水源，雪是高海拔水文循环的重要组成部分。山地积雪的潜在快速和加速变化将对下游的物理、生物和人类系统产生级联效应。然而，我们目前对山地积雪和融雪的时空变异性的理解有限，这阻碍了我们解决气候变化对水文影响的能力。在国家科学研究委员会发现基金的支持下，我的山地雪水文学（MOSH）研究小组将把重点放在当地、区域和全球山地积雪上，作为长期研究计划的一部分。*** MOSH研究小组将侧重于三个相互关联的主题。首先，我们将在拟建的valmount冰川度假区建立多学科山地观测站，并对山地积雪进行详细的实地研究。其次，我们将通过分析历史雪观测，以及有针对性的遥控飞机系统（RPAS，或无人机）和光探测和测距（LiDAR）研究，对加拿大西部的雪气候进行细致的了解。MOSH的第三个研究主题将从遥感和建模的角度关注基本上未受监测的山区盆地的积雪。山地积雪变化与年际气候变率和长期趋势有关；因此，对山区积雪积累模式和融化过程的改进观测和理解将在广泛的应用范围内推进我们的气候变化影响理论。这些应用包括冰川质量平衡、永久冻土解冻和山地灾害、业务水文学、旅游、森林火灾灾害和大尺度大气环流变化。***随着高海拔山地天文台的建立和MOSH实验室的发展，UNBC和加拿大西部将成为山地研究的焦点。通过我的发现基金培训的高素质人才（HQP； 2名博士，3名硕士，4名理学士）将在实地工作，遥感，地理空间处理和分析以及技术写作方面发展可翻译和可就业的技能。我的研究项目将提高我们对山区积雪过去、现在和未来潜在变化的认识，支持和扩大一个富有成效的协作网络，并将扩大和提高我们对高海拔地区变化及其下游影响的理解

Mountain regions around the world are vital sources of water, and snow is a critical component of high-elevation hydrologic cycles. Potentially rapid and accelerated changes in mountain snowpacks will have cascading effects on downstream physical, biological, and human systems. Yet our current understanding of the spatial and temporal variability in mountain snow accumulation and snowmelt is limited, and this hinders our ability to address the hydrological impacts of climate change. With the support of an NSERC Discovery Grant, my MOuntain Snow Hydrology (MOSH) research group will focus on local, regional, and global mountain snowpacks as part of a long-term research program. ***The MOSH research group will focus on three interrelated themes. First, we will establish a multi-disciplinary mountain observatory at the proposed Valemount Glaciers Resort, and conduct detailed field studies on mountain snowpacks. Second, we will develop a granular understanding of snow climates in western Canada through analyses of historical snow observations, and targeted Remotely Piloted Aircraft System (RPAS, or drone) and Light Detection and Ranging (LiDAR) studies. The third MOSH research theme will focus on snow in largely unmonitored mountain basins from remote sensing and modelling perspectives. Mountain snowpack changes are linked to interannual climate variability and long-term trends; improved observations and understanding of mountain snow accumulation patterns and melt processes will thus advance our theories of climate change impacts across a broad range of applications. These applications include glacier mass balance, permafrost thaw and mountain hazards, operational hydrology, tourism, forest fire hazards, and large scale atmospheric circulation changes.***With the inception of a high-elevation mountain observatory and the development of the MOSH lab, UNBC and western Canada will become a focal point for mountain research. Highly Qualified Personnel (HQP; 2 PhD, 3 MSc, 4 BSc) trained through my Discovery Grant funds will develop translatable and employable skills in field work, remote sensing, geospatial processing and analysis, and technical writing. My research program will advance our knowledge of past, present, and potential future changes in mountain snowpacks, support and expand a productive collaborative network, and will broaden and improve our understanding of changes in high-elevation areas and their downstream impacts.**
