摘 要: 获取准确的降水量是研究气候变化以及水文循环的基础,国内外学者针对雨量筒降水量捕捉率不足的问题做了大量工作。对近几十年来国内外降水量对比观测及雨量筒降水量修正方面的研究进行综述,认为目前对液态降水修正方案较为成熟,但是对固态降水尚未形成一个统一的修正标准。主要原因在于目前的降水量修正方案缺少对降水微过程的考虑。充分考虑降水微过程是给出包含物理意义降水量修正方案的关键。另外,更为细致的降水类型判定方案以及对微量降水事件的记录也是确定降水修正方案需要重点解决的问题。 Accurate precipitation is the basis for better understanding the climate change and water cycle process. The domestic and foreign scholars have done a great deal of work for the insufficient catch rate of rain gauges. A review of recent studies on correction of errors in precipitation measurement was given in this paper. It is considered that the correction scheme for liquid precipitation is mature at present, but there is not a uniform standard for solid precipitation correction. The main reason is that the current precipitation correction schemes are lack of consideration of precipitation micro process. The full consideration of the precipitation micro process is the key to the correction of precipitation with physical significance. In addition, more detailed precipitation type determination and the record of light precipitation events are also key problems to determine the precipitation correction scheme.
