From the aspect of global drought monitoring, improving regional monitoring method is becoming increasingly important for sustainable development agriculture and economy. The standardized precipitation conversion index (SPCI) calculated by Global Navigation Satellite System (GNSS) observation a new means that has advantages simple calculation real-time monitoring. However, only SPCI with 12-mon...

As an important ecological security barrier in northern China, the Inner Mongolia Autonomous Region (hereinafter referred to as Mongolia) is seriously affected by drought. It of great significance characterize spatial distribution drought and identify influencing factors Due complex interactions among driving factors, it difficult quantify contribution each factor using linear correlation analy...

This study analyses long-term changes in drought indices (Standardised Precipitation Index—SPI, Standardised Precipitation–Evapotranspiration Index—SPEI) at 1 and 3 months scales 182 stations 11 central eastern European countries during 1949–2018. For comparative purposes, the necessary atmospheric evaporative demand (AED) to obtain SPEI was calculated using two methods, Hargreaves-Samani (SPEI...

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...

BACKGROUND & OBJECTIVES Group C and group G streptococci (together GCGS) are often regarded as commensal bacteria and their role in streptococcal disease burden is under-recognized. While reports of recovery of GCGS from normally sterile body sites are increasing, their resistance to macrolides, fluoroquinolone further warrants all invasive β haemolytic streptococci to be identified to the spec...

Atmospheric drought in lowlands in Slovakia is analyzed on the bases of Standardised Precipitation Index (SPI) and Standardised Precipitation Evapotranspiration Index (SPEI). This paper gives information about the dynamic, intensity, seasonal and territorial differences in occurrence of drought with various intensity: mild (near to normal), moderate, severe and extreme for the period 1961–2011....

The paper presents the re e tion fa ilities of the spe i ation language Slam-sl. Slam-sl is an obje t oriented spei ation language where lass methods are spe i ed by pre and post onditions. The re e tion apabilities permit managing these pre and post onditions in spe i ations what means that semanti re e tion is possible. The range of interesting appli ations is very wide: formal spe i ation of...

Effective identification of drought-related events and quantitative analysis the spatio-temporal evolution drought are essential for regional disaster prevention mitigation sustainable development. Based on monthly precipitation average temperature data from 113 grid points in Liaohe River Basin (LRB) 1961 to 2018, this study evaluated standardized evapotranspiration index (SPEI) monthly, quart...
