摘　　要：利用2000-2014年常规观测资料和NECP/NCAR再分析资料对黑龙江省北部山区的漠河、塔河、新林、加格达奇和伊春等5个代表站浓雾发生的气候特点和产生条件进行统计分析,利用天气学原理对环境条件与浓雾生消的关系进行讨论,利用条件迭代法对2014年5-10月08时伊春站的浓雾过程进行预报,并进行相关的预报检验。结果表明,黑龙江省北部山区的浓雾多发生在5-10月,北部山区东南部的浓雾发生日数有逐年上升的趋势,西北部有下降趋势;除形势稳定有利于浓雾发生外,一定程度弱的上升运动也有利于浓雾的出现。Using regular observation data and NECP/NCAR reanalysis data from 2000-2014, the climatic characteristics and conditions of dense fog in 5 representative stations including Mohe, Tahe, Xinlin, Gagdaqi and Yichun in the northern mountainous areas of Heilongjiang Province were statistically analyzed. The relationship between environmental conditions and dense fog elimination is discussed by using the theory of weather, and the fog process happened at 8 o＇clock in Yichun station from May to October, 2014 is predicted by using the conditional iterative method, and the relevant forecast test is carried out. The results show that, the dense fog in the mountainous areas of northern Heilongjiang occurred mostly in 5-10 months. The number of dense fog days in the southeastern part of the northern mountain area has been increasing year by year, and there is a downward trend in the northwest. In addition to the stable situation conducive to the occurrence of heavy fog, a certain degree of weak upward movement is also conducive to the emergence of dense fog.
