[1] Mapped correlations between annual discharges (AD 1938–1990) of the major Eurasian rivers entering the Arctic Ocean (Severnaya Dvina, Pechora, Ob’, Yenisey, Lena, and Kolyma) demonstrate a positive relationship between discharge and the Palmer Drought Severity Index (PDSI) within the individual basins and more distant areas. The relationship between recent discharge and PDSI supports the ap...

[1] A robust ring-width chronology developed from two sites of Picea schrenkiana in the central Tien Shan area of northwest China was employed to study regional drought variability. Our analyses demonstrate both temperature and precipitation have significant effects on tree growth, thus both should be considered for climate reconstruction. Regional drought history (1675–2002 A.D.) was therefore...

The Nebraska Sand Hills (NSH) lies in the western part of Nebraska, United States. We chose north-eastern, central, and parts NSH with distinct climate, topography, hydrology. study assesses response hundreds shallow groundwater-fed lakes to drought. Total lake area (TLA), determined by classifying Landsat satellite images from 1984 2018, was juxtaposed published Palmer Drought Severity Index (...

As a common natural disaster, drought can significantly affect the agriculture productivity and human life. Compared to Southeast China, Northwest China is short of water year-round most frequent disaster area in China. Currently, there are still many controversial issues monitoring recent decades. To further understand causes changes we chose Shaanxi, Gansu, Ningxia provinces (SGN) as our stud...

Abstract Managers typically estimate wildlife abundance using surveys within a timeframe that favors increased detectability; however, the ability to account for probabilities of inclusion, detection, and/or presence given sampling area is often limited. Cranes provide good opportunity research count accuracy because they are large, conspicuous, and congregate during part year, on staging areas...

The National Agricultural Decision Support System (NADSS) is a web based geospatial decision support system used to aid producers and decision makers in analyzing and effectively mitigating the effects of drought. The NADSS application is unique in its implementation, containing web-based implementations of commonly utilized drought indices including the Newhall Simulation Model (NSM), Palmer D...

The devastating socioeconomic impacts of recent droughts have intensified the need for improved drought monitoring in South Africa (SA). This study has shown that not all indices can be universally applicable at regions worldwide, and there is no single index represent aspects droughts. aim this was to review performance applicability Palmer severity (PDSI), surface water supply (SWSI), vegetat...

Wildfire predictions provide useful information for fire management planning and implementation. Temperature precipitation have been used as the primary meteorological predictors wildfires in China. This study is to improve prediction skills of long-range (monthly, seasonal, annual) China by identifying other important predictors. Provincial data during 1999–2020 were calculate correlations bet...
