We present a microlevel study to simultaneously investigate the effects of variations in temperature and precipitation along with sudden natural disasters to infer their relative influence on migration that is likely permanent. The study is made possible by the availability of household panel data from Indonesia with an exceptional tracking rate combined with frequent occurrence of natural disa...

Accounting for the interannual climatic variations is a well-known issue for simulation-based studies of environmental systems. It often requires intensive sampling (e.g., averaging the simulation outputs over many climatic series), which hinders many sequential processes, in particular optimization algorithms. We propose here an approach based on a subset selection in a large basis of climatic...

Epidemiological studies of the relationship between climate and the onset of aneurysmal subarachnoid hemorrhage (SAH) have been reported in the temperate and subarctic latitudes. However, the relationship between the incidence of aneurysmal SAH and the climatic variations in the subtropical region remains uncertain. Epidemiological analysis requires study of an extremely isolated area. This stu...

Variations in tree-ring structure are simulated with (1) an empirical model using monthly climatic data as statistical predictors and (2) a mechanisbc model using daily climatic data as growth limiting conditions. The empirical model calibrates standardized ring-width and density chronologies of tree-rings with monthly temperature, precipitation or Palmer Drought Severity Index. The empirical m...

â â  a great portion of precipitation in the south western iran falls in the snow formation. surface runoff produced from melting snow has an important role in the recharging ground water, surface and subsurface flows. rapid snowmelt can even cause flooding . since the snowmelt cannot be easily detected from optical satellite images, snow cover area (sca) is derived as an important hydrological...

this study tried to explore disciplinary variations of web blurbs across soft and hard knowledge fields on the one hand, and to illustrate how academic publishers exploit interactional metadiscourse devices in move structure of their blurbs on the other.

This paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. The purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. We have employed a multi-method approach which combines a “qualit...

BACKGROUND Owing to the emergence of some challenges in the demographic structure of many countries and possible decrease in young human workforce in the future decades, the reduction in the fertility rate has become a major public concern. This study aimed to investigate the effects of climatic factors on fertility. AIM In this correlational study conducted during 2005-2009, the relationship...
