摘要: 比较中国不同观测站网1971—2010年平均风速及其变化趋势的监测差异发现:不同站网监测的中国平均年、季、月风速均存在一定的差异,但相对差异在±10%之间;对平均风速空间分布的监测效果差异较大,其中基本基准站和基本站网对东北和华南的监测结果较好,特别是基本基准站对全国大部分地区的监测均接近标准站网;各级监测站网得到的中国平均风速变化都呈下降趋势;从风速变化趋势的空间分布上来看,几个站网的监测效果均不理想。

关键词: 站网密度, 风速, 气候监测, 差异

Abstract: Based on the daily surface wind speed data during 1971-2010 in China, a comparative analysis of changes of mean wind speed in four subset networks with different station densities relative to the full-size national network (standard network) was conducted. The results show that China-wide mean wind speed varied in the four networks, but the absolute value of the relative difference of mean wind speed is below 10%. The spatial distribution of the wind speed in the basic baseline stations and basic stations come closest to that in the standard network. All networks can detect the downtrend of annual wind speed during 1971-2010, the basic baseline stations and basic stations witness smaller differences. In the case of spatial distribution of wind speed, the monitoring results of these networks are unsatisfactory.

Key words: station density, wind speed, climate change
