| 1 | Changes in terrestrial surface dry and wet conditions on the Loess Plateau(China) during the last half century显示文摘This paper,using a revised Penman-Monteith model,computed the terrestrial surface humidity index of the Loess Plateau(China) based on climatic factors of monthly mean temperature,maximum temperature,minimum temperature,relative humidity,precipitation,wind speed and sunshine duration observed on the plateau from 1961 to 2008.The temporal-spatial distribution,anomaly distribution and sub-regional temporal variations of the terrestrial surface dry and wet conditions were analyzed as well.The results showed a decreasing trend in the annual average surface humidity from the southeast to the northwest in the research area.Over the period of 1961-2008,an aridification tendency appeared sharply in the central interior region of the Loess Plateau,and less sharply in the middle part of the region.The border region showed the weakest tendency of aridification.It is clear that aridification diffused in all directions from the interior region.The spatial anomaly distribution of the terrestrial surface dry and wet conditions on the Loess Plateau can be divided into three key areas:the southern,western and eastern regions.The terrestrial annual humidity index displayed a significantly descending trend and showed remarkable abrupt changes from wet to dry in the years 1967,1977 and 1979.In the above mentioned three key areas for dry and wet conditions,the terrestrial annual humidity index exhibited a fluctuation period of 3-4 years,while in the southern region,a fluctuation period of 7-8 years existed at the same time. | YuBi YAO RunYuan WANG JinHu YANG Ping YUE DengRong LU Guo,Ju XIAO Yang WANG LinChun LIU | 2013 | Journal of Arid Land2013，5，1： | 14 |
| 2 | Causes and Changes of Drought in China:Research Progress and Prospects显示文摘Drought is one of the most serious and extensive natural hazards in the world.Subject to monsoon climate variability,China is particularly influenced by drought hazards,especially meteorological drought.Based on a comprehensive understanding of the current status of international drought research,this paper systematically reviews the history and achievements of drought research in China since the founding of the People’s Republic of China,from four main perspectives:characteristics and spatiotemporal distribution of historical and recent drought events,drought formation mechanism and change trend,drought hazard risk,and the particular flash drought.The progress and problems of drought research in China are analyzed and future prospects are proposed,with emphasis on the multi-factor synergetic effect for drought formation;the effect of land-atmosphere interaction;identification,monitoring,and prediction of flash drought;categorization of drought and characteristics among various types of drought;the agricultural drought development;drought response to climate warming;and assessment of drought hazard risks.It is suggested that strengthening scientific experimental research on drought in China is imperative.The present review is conducive to strategic planning of drought research and application,and may facilitate further development of drought research in China. | Qiang ZHANG Yubi YAO Yaohui LI Jianping HUANG Zhuguo MA Zhilan WANG Suping WANG Ying WANG Yu ZHANG | 2020 | Journal of Meteorological Research2020，34，3： | 8 |
