Snow Avalanche Climate and Variations in the Intermountain Zone of the Western United States

Mock，C.J.和Birkland，K.W.这项研究考察了山间山脉西部的雪崩气候学。基本目标是：(1)-evaluate-the-spatio-temporal-variability-of-snow和雪崩气候；(2)利用气候和雪崩数据之间的当代关系重建较长期的雪崩记录；(3)分析可能影响雪崩反应的时间、重现和空间变异性的天气尺度气候学；以及(4)探索雪崩气候在气候变化情景下的可能反应。有关气候、积雪、雪崩和大气过程的数据将从西域雪崩网络和SNOTEL等现有大型档案以及积雪调查记录和长期气候记录中汇编。研究结果将对(A)雪崩预报、(B)了解雪崩活动的物理过程、(C)改进危险管理和划定以及(D)科学了解山区环境具有重要意义。

MOCK, C.J. and BIRKELAND, K.W. The study examines the snow avalanche climatology of the intermontane west. The basic objectives are to: (1)-evaluate-the-spatio-temporal-variability-of-snow and avalanche climates; (2) reconstruct longer-term avalanche records using contemporary relationships between climate and avalanche data; (3) analyze the synoptic scale climatology that may affect the timing, recurrence, and spatial variability of avalanche responses; and, (4) explore possible responses of snow avalanche climates under climatic change scenarios. Data on climatic, snowpack, avalanche, and atmospheric processes will be compiled from existing large archives such as the Westwide Avalanche Network and SNOTEL and from snow survey records and long-term climate records. The results will be important to (a) avalanche forecasting, (b) understanding the physical processes of avalanche activity, (c) improved hazard regulation and delineation, and (d) scientific understanding of mountain environments.
