一、大气降水的时空分布及其特点(一)年降水量的分布:降水量的分布状况主要受季风环流的支配,还受地形的影响。因此造成在地域上分配极不均匀。本省平均降水量在340-820毫米之间。其地域分配是,燕山南鹿为700—820毫米,是全省降水量最多的地区;张家口地区西北部不足400毫米,是全省降水量最少的地区;太行山东麓及沿海降水量较多,为600—700毫米;束鹿、宁晋、南宫一带降
First, the spatial and temporal distribution of atmospheric precipitation and its characteristics (A) the distribution of annual precipitation: the distribution of precipitation is dominated by the monsoon circulation, but also by the terrain. Thus resulting in a very uneven geographical distribution. The province’s average precipitation between 340-820 mm. Its geographical distribution is that the south deer Yarlung is 700-820 mm, which is the area with the most precipitation in the province. The less than 400 mm in the northwest of Zhangjiakou area is the area with the least precipitation in the whole province. There are more precipitation in the foot of Shandong and the coast of Taihang, 600-700 mm; beam deer, Ning Jin, Nangong down
