This study uses two forms of the Palmer Drought Severity Index (PDSI), namely PDSI_TH (potential evapotranspiration estimated-by Thornthwaite equation) and PDSI_PM estimated by FAO Penman-Monteith equation), to characterize meteorological drought trends during 1960–2016 in Loess Plateau (LP) its four subregions. By designing a series numerical experiments, we mainly investigated various climati...

Abstract. Drought indices are hard to balance in terms of versatility (effectiveness for multiple types drought), flexibility timescales, and inclusivity (to what extent they include all physical processes). A lack consistent source data increases the difficulty quantifying drought. Here, we present a global monthly drought dataset with spatial resolution 0.25? from 1948 2010 based on multitype...

Change in climate and water cycle will challenge water availability but it will also increase the exposure to unsafe water. Floods, droughts, heavy storms, changes in rain pattern, increase of temperature and sea level, they all show an increasing trend worldwide and will affect biological, physical and chemical components of water through different paths thus enhancing the risk of waterborn...

The geographic range of many temperate plant species is constrained by climate, but it remains little known how climate affects population performance at low-latitude range margins. This study investigated the reproduction of the Eurasian tree Frangula alnus in relict populations near its southwestern range limit in southern Spain. The aim was to identify the principal stages and causes of ovul...

Spring-summer winds from the south move moist air from the Gulf of Mexico to the Great Plains. Rainfall in the growing season sustains prairie grasses that keep large dunes in the Nebraska Sand Hills immobile. Longitudinal dunes built during the Medieval Warm Period (800 to 1000 years before the present) record the last major period of sand mobility. These dunes are oriented NW-SE and are compo...

abstract drought is one the most complicated and unknown natural disasters and rainfed agriculture is often the first sector to be affected by drought. in this research, we consider the drought monitoring from both meteorological and agricultural points of view. we have selected standardized precipitation index (spi) among the meteorological indices, with a one month time scale for the synoptic...
