Drought is a natural event that very influential on the availability of water reserves in soil, both needed for agricultural purposes and human needs. The Irrigation Areas (DI) conducted by study are Pandanduri-Swangi, Rutus, Terara Temusik which located Palung River Basin. This Analysis includes Rainfall, Regional Evaporation, calculation drought Palmer Severity Index (PDSI) method. Then do co...

Droughts are a natural, recurrent climate extreme that can inflict long-lasting devastation on natural ecosystems and socio-economic sectors. Unlike other hazards, drought onset is insidious often affects greater spatial extent over prolonged temporal scale. In the United States evolution of its impacts typically region-specific intensified precipitation variability may obscure how manifest. th...

BACKGROUND Health related quality of life is an important outcome measure in studies involving patients with chronic neurological conditions. Disease specific patient reported outcome measures (PROMs) are increasingly used as primary end points in clinical trials. The most widely used disease specific PROM is the 39 item Parkinson's Disease Questionnaire (PDQ-39). The aim of this study was to d...

Droughts can severely reduce the productivity of agricultural lands and forests. The United States Department of Agriculture (USDA) Southeast Regional Climate Hub (SERCH) has launched the Lately Identified Geospecific Heightened Threat System (LIGHTS) to inform its users of potential water deficiency threats. The system identifies droughts and other climate anomalies such as extreme precipitati...

Moisture conditions, especially those that occur as multi-decadal anomalies, have profound impacts on society, in arid and semi-arid regions. However, the lack of high-resolution climate data for first millennium CE greatly limits our understanding how moisture variations influenced history. Here, we present an 1882-year (134–2015 CE) tree-ring chronology developed from Qilian juniper (Juniperu...

This study systematically reviews the under-researched experience of performance indices to determine extreme hydroclimate in tropical Southeast Asia. The review was conducted by Preferred Reporting Items for Systematic Review and Meta-Analysis methods with SCOPUS databases. screening articles is based on inclusion exclusion criteria encompassing published between 2000 2021 solely focused three...

Drought is a complex hazard, and it has an impact on agricultural, ecological, and socio-economic systems. The vegetation condition index (VCI), which is derived from remote-sensing data, has been widely used for drought monitoring. However, VCI based on the normalized difference vegetation index (NDVI) does not perform well in certain circumstances. In this study, we examined the utility of th...

The North American Monsoon delivers warm season precipitation to much of the southwestern United States, yet the importance of this water source for forested ecosystems in the region is not well understood. While it is widely accepted that trees in southwestern forests use winter precipitation for earlywood production, the extent to which summer (monsoon season) precipitation supports latewood ...

Drought is one of the most devastating natural disasters, especially in China. In drought assessment, PDI has high robustness, easier to obtain than indices such as SPEI and PDSI, more advantageous regions with sparse stations. The present study employs annual precipitation temperature data from 830 meteorological stations systematically interannual variation characteristics humidity China duri...

In this report we describe how we adapted the Parallel Log Structured Filesystem (PLFS) to enable HPC applications to be able read and write data from the HDFS cloud storage subsystem. Our enhanced version of PLFS provides HPC applications with the ability to concurrently write from multiple compute nodes into a single file stored in HDFS, thus allowing HPC applications to checkpoint. Our resul...
