Abstract

A physical snowpack model was forced by observed meteorological data to map the snow melting distribution over the Jozankei Dam basin, Sapporo, Japan. First, the snowpack model experiment forced by radar precipitation reasonably reproduced the snow environment in the basin, although it underestimated the snow depth in the northern area. Second, the map of the basin showed that the average difference in snowmelt was 22 days between upstream and downstream. On the other hand, the timing when melt forms become dominant in the snow layer was little affected by altitude and precipitation, and the dam inflow attained the peak 35 to 40 days after then.

基于积雪模拟的约赞溪坝流域融雪估算

利用观测到的气象资料，建立了一个物理积雪模型，绘制了日本札幌Jozankei坝流域的融雪分布图。①雷达降水强迫积雪模式试验较好地再现了流域内的积雪环境，但低估了北部地区的雪深;第二，流域地图显示上下游融雪平均差22天。另一方面，融水形态在雪层占主导地位的时间受海拔和降水的影响较小，大坝入流在此之后35 ~ 40 d达到峰值。

期刊介绍： SOLA (Scientific Online Letters on the Atmosphere) is a peer-reviewed, Open Access, online-only journal. It publishes scientific discoveries and advances in understanding in meteorology, climatology, the atmospheric sciences and related interdisciplinary areas. SOLA focuses on presenting new and scientifically rigorous observations, experiments, data analyses, numerical modeling, data assimilation, and technical developments as quickly as possible. It achieves this via rapid peer review and publication of research letters, published as Regular Articles. Published and supported by the Meteorological Society of Japan, the journal follows strong research and publication ethics principles. Most manuscripts receive a first decision within one month and a decision upon resubmission within a further month. Accepted articles are then quickly published on the journal’s website, where they are easily accessible to our broad audience.
