摘要
回顾国内外有关海(湖)效应降雪的主要研究成果,依据海(湖)效应降雪的定义,对其产生机制、大尺度环流背景及多尺度相互作用、影响因素和空间形态分类等方面进行的总结和分析。表明,海(湖)效应降雪过程存在多尺度相互作用,海(湖)气温差、热力不稳定、风向风速、地形、云物理过程等是其关键影响因素,并影响其空间分布形态。数值模拟和多普勒雷达资料是主要研究手段。在此基础上,经进一步分析指出,未来我国应重点深入开展海效应降雪的空间分布形态及其产生机制研究,提高海效应降雪的精细化预报能力。
The main research advances of Ocean （lake）-effect Snow （OLES） in recent years are reviewed in this paper. The definition, mechanism, large scale circulation background and multi-scale interaction, influence factor, classification of spatial shape, and so on are summarized. Multi-scale interaction is found in OLES.Temperature difference of ocean （lake） and air, wind direction and speed, stability, topography and microphysics processes are the critical influence factor for OLES, which also decide the spatial distribution of snowfall. Model simulation and Doppler radar data is the leading methods in the field in the past years. Based on the reviews, the authors put forward the further research on OLES including classification of spatial shape and their influence factor in China. In this way, accuracy forecasting ability will be enhanced.
