用一个简单的数值模型模拟了与日本海冷气团爆发变化相关的降雪。该模型结合了气海界面上的动量、热量和水分通量的影响以及地形的影响。将模拟的降雪、温度、风和湿度分布与观测值进行比较，发现存在合理的一致性。进行了数值实验，以确定降雪分布对大范围普遍条件的依赖性。结果表明，降雪的发生主要受地形抬升的控制。一个意外的发现是，降雪分布对盛行水流的干燥程度并不十分敏感。 DOI：10.1111/j.2153-3490.1976.tb00672.x
Snowfall associated with the modification of cold air-mass outbreaks by the Sea of Japan is simulated with a simple numerical model. The model incorporates the effects of momentum, heat, and moisture fluxes across the air-sea interface as well as the effects of orography. The simulated distributions of snowfall, temperature, wind, and moisture are compared with observations and reasonable agreement is found. Numerical experiments were made in order to determine the dependence of the snowfall distribution on the large scale prevailing conditions. The results indicate that the occurrence of snowfall is controlled primarily by orographic lifting. An unexpected finding is that the snowfall distribution is not very sensitive to the dryness of the prevailing flow. DOI: 10.1111/j.2153-3490.1976.tb00672.x
