abstarct development of greenhouse gases in future periods not only causes change in average amounts of climate variables but also makes variables of this variability affected. then for sure concerning alternations followed with climate variables’ fluctuations and its average amounts in effecting on runoff would make more reliable results. in this inquiry initially fluctuations and average amou...

This paper examines statistical approaches for interpolating climatic data over large regions, providing a brief introduction to interpolation techniques for climate variables of use in agricultural research, as well as general recommendations for future research to assess interpolation techniques. Three approaches—1) inverse distance weighted averaging (IDWA), 2) thin plate smoothing splines a...

analysis of the spatial and temporal trends of precipitation and temperature are pertinent for future development and sustainable management of water resources in a given region. in this paper, we present a study concerning the climatic behavior of two principal observables variables, viz. monthly temperature (maximum and minimum) and mean precipitations obtained from the measurements carried o...

evapotranspiration is one of the most important components of the hydrological cycle which is directly influenced by atmospheric conditions. this study investigated annual and seasonal trends in reference evapotranspiration (et0) and its key influencing climatic variables during 1966-2005 at 10 stations in southern iran (with centrality of fars province). first, multivariate regression analysis...

BACKGROUND The purpose of this study was to drawing a regression model of organizational climate of central libraries of Iran's universities. METHODS This study is an applied research. The statistical population of this study consisted of 96 employees of the central libraries of Iran's public universities selected among the 117 universities affiliated to the Ministry of Health by Stratified S...

food security in the world that water shortages are faced is very important, especially in arid regions. effects of climate change on agricultural water requirement have doubled this importance. in this study, the risk of water demand has been assessed for a wide range of products under climate change. aogcm models have been used to simulate climate variables. the climate change scenarios of cl...

background : zoonotic cutaneous leishmaniasis (zcl), an important public health problem in iran, is sensitive to climate conditions. this study aimed to examine dynamic relations between the climate factors and incidence of zcl in golestan province, northern iran during 2010–2012. methods : data of monthly climatic factors, including temperature variables, relative humidity variables, evaporati...

1. Two dominant drivers of species distributions are climate and habitat, both of which are changing rapidly. Understanding the relative importance of variables that can control distributions is critical, especially for invasive species that may spread rapidly and have strong effects on ecosystems. 2. Here, we examine the relative importance of climate and habitat variables in controlling the d...
