【摘要】：基于1971—2009年葫芦岛市4站逐日的地面水汽压和降水资料,计算了每个站整层大气可降水量、有效空中水资源量、自然降水产出率以及人工增雨(雪)潜力值,分析了其时空特征和多年变化趋势。结果表明:(1)葫芦岛年平均整层大气可降水量为5 436~6 543mm,呈现出沿海高,内陆低的特点,有效空中水资源量为1 742~1 971mm,约为整层大气年可降水量的1/3,总体呈现出南部略大,北部略小的特点;(2)39a间自然降水产出率平均为32%,多年月平均自然降水产出率大值多出现在4月,小值多出现在6月和9月;(3)葫芦岛地区全年人工增雨(雪)潜力值为1 211~1 370mm,约为该地区39a平均降水量的(574mm)2.2倍,最大值均出现在7月,最小值出现在12月或者1月,夏季(6—8月)的可开发潜力值约占全年的70%。
[Abstract]:Based on the daily surface vapor pressure and precipitation data of four stations in Huludao City from 1971 to 2009, the precipitable water volume, the effective air water resources, the natural precipitation output rate and the potential value of artificial precipitation (snow) were calculated for each station. The temporal and spatial characteristics and the variation trend of Huludao are analyzed. The results show that the average annual precipitation of the whole layer of Huludao is 5 436 ~ 6 543 mm, which shows the characteristics of high coastal and low inland. The effective air water resources are about 1 / 3 of the annual precipitable water in the whole atmosphere, which is about 1 / 3 of the annual precipitable water in the whole atmosphere. In general, the water resources in the air are slightly larger in the south and slightly smaller in the north. The average output rate of the natural precipitation in the period of 39 years is 32. The large value of the annual precipitation output rate in many years appears in April. In Huludao area, the potential value of artificial rain (snow) is 1 2111 ~ 1 370 mm, which is about 2.2 times of the average precipitation in 39 years in this area. The maximum value appears in July, and the minimum value appears in July or #datea-, the maximum value is in July, and the maximum value is in July, and the maximum value is in July, and the maximum value is about 2.2 times that of the average precipitation of 39 years in Huludao area. The exploitable potential value of summer is about 70% of the whole year.
