Background The national standard of the Classification of Meteorological Drought (GB/T 20481-2006) was developed by the National Climate Center in cooperation with Chinese Academy of Meteorological Sciences,National Meteorological Centre and Department of Forecasting and Disaster Mitigation under the China Meteorological Administration (CMA),and was formally released and implemented in November 2006.In 2008,this Standard won the second prize of the China Standard Innovation and Contribution Awards issued by SAC.Developed through independent innovation,it is the first national standard published to monitor meteorological drought disaster and the first standard in China and around the world specifying the classification of drought.Since its release in 2006,the national standard of Classification of Meteorological Drought has been used by CMA as the operational index to monitor and drought assess,and gradually used by provincial meteorological sureaus,and applied to the drought early warning release standard in the Methods of Release and Propagation of Meteorological Disaster Early Warning Signal. 相似文献

1.我国的风能资源
风能的大小用风功率密度(W/m^2)来度量,它与空气密度和风速的立方成正比。我国的风能资源,据中国气象科学研究院对全国900多个气象站年平均风能功率密度的估算,10m高度层的总资源量为3226GW。假设其中1/10在技术上可供开发,并考虑风轮扫掠面积系数0.785. 相似文献
