Increasing global warming can potentially increase the intensity of ENSO and IOD extreme phenomena in future, which could potential for wildfires. This study aims to develop a hotspot prediction model Kalimantan region using climate indicators such as precipitation its derivatives, IOD. The was developed Principal Model Analysis (PMA) initial basis. overall performance is evaluated concept Cros...

BACKGROUND Many studies have reported associations between temperature extremes and cardiovascular mortality but little has been understood about differences in the effects on acute and chronic diseases. The present study examines hot and cold spell effects on ischaemic heart disease (IHD) mortality in the Czech Republic during 1994-2009, with emphasis upon differences in the effects on acute m...

The Madden Julian oscillation (MJO) is known as the primary mode of large-scale inter-seasonal variability in tropical regions, affectimg equatorial and sub-tropical climates. This study investigated the effects of the MJO on the occurrence of wet and dry spells in Fars province, central southern part of Iran, during November-April. Monthly precipitation data of nine stations spread over variou...

Breath-holding spells are benign, paroxysmal events with apnea and postural tone changes after a crying episode in infants. The objective of this study was to investigate the pathologies in brain metabolite values in the absence of seizure in children with breath-holding spells by using magnetic resonance spectroscopy (MRS). Brain MRS examination was performed on 18 children with breath-holding...

Abstract The paper discusses the impact of atmospheric circulation on occurrence droughts. research includes mean monthly discharges for 7 rivers in 1954–2018. Dry periods were determined with Standardised Streamflow Indices (SSI-12). Additionally, type calendar Central Poland was used to determine indices: western zonal (W), southern meridional (S) and cyclonicity (C). analyses indicated a var...

This paper investigates the persistence of poverty over individuals' lifetimes using a hazard rate approach that accounts for multiple spells of poverty and incorporates spell duration, individual and household characteristics, and unobserved heterogeneity. The findings highlight the importance of considering multiple spells in an analysis of poverty persistence, with half of those who end pove...

Characterising ocean temperature variability and extremes is fundamental for understanding the thermal bounds in which marine ecosystems have adapted. While there growing evidence of how heatwaves threaten ecosystems, prolonged periods extremely cold temperatures, cold-spells, received less global attention. We synthesize literature on their ecological impacts physical mechanisms. Ecological th...

Evaporation losses of rainfall intercepted by canopies depend on many factors, including the temporal scale observations. At event scale, interception is a few millimetres, whereas at larger number times that canopy filled and then depleted can make an important fraction depth. Recently, simplified interception/evaporation model has been proposed, which considers modified Merrian to compute dur...
