降尺度技术的应用研究进展
Recent Advances on the Application for the Downscaling Technology
中文摘要：
大量数值预报产品的应用表明，尽管许多数值预报产品的参考价值很高，但预报的结果总存在一些误差，数值模式精细化预报准确性和可靠性至今仍存在不少问题。基于现有条件，对数值预报产品进行降尺度将成为精细化预报方法研究的一个热点。降尺度技术作为一种新的精细化预报途径，已成为一个重要的研究领域。为此，本文对降尺度技术的概念、该技术中各个方法的优缺点进行了概述，归纳了该技术在国内外的研究进展，为降尺度技术在数值模式中的应用研究提供参考。

Abstract：
A great number of applications of NWP (Numerical Weather Prediction) products show that, although many NWP products have a high reference value, the prediction results always have some deviations. Moreover, problems about the accuracy and predictability of the fine forecasting by numerical models still exist so far. Conducting the downscaling interpretation to the NWP product will be a hot spot in the fine forecasting research. Downscaling techniques, as a new way to fine forecasting, have become an important field for study. In this paper, the concept for downscaling techniques, the technology advantages and disadvantages of each method are outlined. Technology in the domestic and foreign research progress in the application of numerical models is summed up for reference.
