中文摘要：

在我国,应用陆面模式准实时监测干旱是一种正在发展的监测方法。从模式强迫资料生成,模式运行及结果后处理和干旱监测产品生成3方面,阐述应用CABLE陆面模式进行干旱监测的过程和实现方法。首先,详述了生成强迫资料所需的各种资料及其插值和订正方法。其次,介绍了应用陆面模式干旱监测的等级判断方法,概述了通过Shell语言和NCO（Net CDF Operator）软件实现干旱监测的自动化运行过程。通过对比模式与自校正帕尔默指数（sc_PDSI）对我国北方1997/1998年干旱监测的效果,发现模式监测干旱的起止时间优于sc_PDSI,发生范围较sc_PDSI更加准确,与实际土壤湿度观测资料结果更为一致。研究表明,陆面模式结果能够反映土壤湿度对于历史同一时期的相对干旱程度,是对土壤湿度长时间观测资料不足的有效补充。研究还发现,应用sc_PDSI监测我国南方干旱时,应当进行参数的本地化订正。

英文摘要：

It is a developing method to monitor drought in near-real time based on land surface model in China.The procedure of forcing data,running of Australian Community Atmosphere and Biosphere Land Exchange Model（ CABLE） and processing of model results,and producing of drought monitoring products were stated in this study.Firstly,the multiple types of data for producing forcing data and the corresponding methods of interpolation and correction were depicted in detail. Then,the methods of drought monitoring and drought classification were introduced,and the automatic process of drought monitoring with Shell scripts and Net CDF Operator（ NCO） was summarized.The comparison between the model results and the self-calibrating Palmer Drought Severity Index（ sc_PDSI） in the1997 /1998 drought event revealed that the model results performed better than sc_PDSI in the drought starting time and ending time as well as the region of drought monitoring. The simulated and measured values of soil moisture content were quite similar,which illustrated that the model results can be used to reflect the relative drought level in history,and they can be used to compensate the scarcity of long-term observed data of soil moisture content. Furthermore,the study showed that it is necessity to make a correction of sc_PDSI when it is used in monitoring drought in south China.
