temperature and precipitation are among important atmospheric parameters for watershed planning. assessment of temperature and precipitation trends is very important for future watershed planning. in this paper, trends of atmospheric parameters such as seasonal and annual temperature and precipitation were examined for the synoptic stations of bandar anzali, rasht, ramsar, babolsar and gorgan. ...

this analysis was conducted on 31 synoptic stations in iran. initially, the mann-kendall test was administered in order to analyse the trend of alterations of these two components over time and the results suggest that 16% of the stations show significant relationship with annual precipitation (positive and negative). more stations showed significant relationships between sunspots and minimum a...

in recent years, mangrove forests with the high economical and environmental value are threatened with extinction by human activities. ex-situ conservation is an appropriate method to conservation this forest. this study was conducted with the purpose of studying the role of climatology factors as one of the most important environmental parameters in dispersion of mangrove forests of hormozgan ...

abstract knowledge of the coordination of the agricultural activities in every region with the weather and climate condition of that area is necessary for any kind of agriculture activity. therefore, understanding the climate and analyzing the ecophysiological characteristics of plants are the most important factors in production. saffron is one of the most valuable plants, which is planted in ...

in this study, we aimed to reconstruct the mean, maximum mean and ‎minimum mean temperature from the chronology of tree rings width of two ‎quercus persica sites in dena region, where efficient climatic data have a ‎short period (1982-2011). the duration of common chronology of the sites ‎is 131 years (1881-2011).considering the strong correlation between ‎climatic data and growth rin...

with respect to wide distribution of a. sieberi besser in iran, various studies have been done on its habitats and different ecological properties have been referred as effective factors in establishment of this species. in this research, we tried to study the ecological range of a. sieberi and its relationship with vegetative characteristics. therefore, climate properties including annual prec...
