中文摘要:
      在进行天气预报,开展天气、气候研究以及制订有关工程计划时,我们往往需要利用气象台站的观测资料来内插非台站所在地的气象要素值。为了保证这些内插值具有一定的精度,气象台站必须达到相应的密度。1946年,O.A.德罗兹多夫[1]曾用结构函数的方法对此作了研究,并得到气象要素的线性内插标准误差仅与该要素的结构函数有关的结论。此后,结构函数被广泛用于气象台站网的合理分布研究[2,3]
英文摘要:
      Based on data of daily air temperature and relative Humidity from 1961 to 1980 over Jianghusi Plain, the structure functions of the two elements have been calculated, and from these the relationships between the error of linear interpolation and distance have been established. According to the principle that the standard error of interpolation should not exceed the slanderd error of observation, the maximum admissible spacings between stations of the second group meteorological networks have been estimated over this area. Finally, it has been found that replacing interpolation along a segment by interpolation in a plane will increase the accuracy of interpolation.
