资料插值的进展

对气候学中资料插值、数值天气预报中的客观分析和气候模拟中的降尺度技术作了统一论述，重点是气候资料插值的原理和进展。由于应用领域不同，这些技术也是很不相同的，但它们的动力学和统计学原理是相近或一致的。近十年来三种插值技术，尤其在建立计算机自动化插值系统方面，都取得了长足进展。

Advance of Data Interpolation

A unified briefing of data interpolation of climatic data, objective analysis of numerical weather forecast and downscaling technique of climate modeling is presented. However, it is an emphasis on the principle and advance of climatic data interpolation. Because of the distinctness of its application fields, these techniques are also different, but their dynamic and statistical principles are close or nearly the same. In recent ten years, three kinds of data interpolation technique,especially on the automatic computer system of data interpolation, have made progress greatly.
