对在朝鲜半岛进行播云试验的可行性进行了全面审查。68个气象站的长期（1971-2000年）降水记录，韩国地形，和播种飞机的不可用性表明，冬季地形云播种实验与冰川颗粒在太白山脉的一些高峰与目标地区的山峰以西，如果条件满足，可能是一个合理的选择，选择降水增强。江原道冬季（11月至3月）降水分布模式和相关的气象数据在大垣岭和索乔气象站表明，在850毫巴的强东风是一个关键，扩大地形产生的降水西部的太白山山峰。与这些降水分布模式相关的最普遍的天气模式是经过朝鲜半岛南部的低压系统，引发逆时针环流，为江原道带来盛行东风。此外，最近两年在大垣岭气象站用微波辐射计测得的液态水深度记录显示，在这些事件期间，液态水的深度值最大。因此，建议这些类型的天气模式与低于冰点温度在播种地点（大壁岭附近的山峰）可能会带来很好的播种潜力。采用Clark-Hall中尺度模式模拟了冰催化剂（银化）的扩散及催化剂对降水的影响。对于人工增雨作业，增雨作业的开始时间是关键，开始时间越早，增雨效果越好。此外，降水增加没有发生在目标区域，播种地点的西坡，但仅限于播种地点的东侧。这些模拟结果说明了在目标区域找到合适的天气条件和催化时间以成功地进行人工增雨的困难。尽管如此，数值模型似乎是一种经济可靠的工具，可以帮助制定良好的播种策略。
Feasibility of cloud seeding experiments in the Korean Peninsula was examined in a comprehensive manner. Long term (1971-2000) precipitation records from 68 weather stations, the Korean topography, and the unavailability of a seeding aircraft suggested that winter orographic cloud seeding experiments with glaciogenic particles at some high peaks of Taebaek Mountain Ranges with target areas to the west of the mountain peaks might be a reasonable option to choose for precipitation enhancement if conditions are met. Wintertime (November-March) precipitation distribution patterns in Gangwon Province and related meteorological data at Daegwallyeong and Sokcho weather stations showed that strong easterly winds at 850 mb was a key to extend orographically generated precipitations to the west of the Taebaek Mountain peaks. The most prevalent synoptic patterns that were relevant to these precipitation distribution patterns were a low pressure system passing over south of the Korean Peninsula, invoking counter-clockwise circulation to bring prevailing easterly winds to Gangwon Province. Furthermore recent two year records of liquid water depths measured by a microwave radiometer at Daegwallyeong weather station showed the largest values during these events. Therefore it was suggested that these types of synoptic patterns with below freezing temperatures at seeding sites (mountain peaks near Daegwallyeong) might pose a good seeding potential. The Clark-Hall mesoscale model was employed to predict dispersion of glaciogenic seeding material (silver iodide) and the effect of seeding on precipitation. For the case chosen for seeding simulation, seeding start time was critical in precipitation enhancement, earlier start time producing more precipitation increase. Moreover, precipitation increase did not occur at the target area, the western slopes of the seeding site, but was limited only to the eastern side of the seeding site. These simulation results illustrate the difficulty of finding the right weather conditions and the seeding time for a successful precipitation enhancement at the target area. Nevertheless, it seems to be demonstrated that a numerical model is an economic and reliable tool to aid in establishing a good seeding strategy.
