The vast pastures and agricultural development plans for dry farming and irrigated farming in Khuzestan Province depend on rain. This requires availability of annual precipitation prediction models to be used in the management decision-making process. In this research, the long-term daily precipitation data from 15 rain gauge stations in the study area were collected for study and a relationshi...

hydrologic regime is highly dependent on climate change, as hydrologic cycle components are directly influenced by climatic conditions. this paper analyzes the impacts of climate change on the hydrologic regime of the atrak river basin in the northeast of iran. it drains to the caspian sea. the data collected at 11 hydrometeorological stations were examined to detect trends in hydroclimatologic...
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. ...

daily precipitation data from aphrodite's water resources with a spatial resolution of 0.25ëfor 57 years has been used to detect the trend of precipitation in azerbaijan republic. first of all monthly, seasonal and yearly maps and regional mean time series calculated. according to the annual map mean annual precipitation of the country is about 410 m.m there are two precipitation maximal ...
Spatial and temporal variability analysis of precipitation is an important task in water resources planning and management. This study aims to analyze the spatial and temporal variability of precipitation in the northeastern corner of Iran using data from 24 well-distributed weather stations between 1991 and 2015. The mean annual rainfall, precipitation concentration index (PCI), and their coef...
simulation of climate change in iran during 2071-2100 using precis regional climate modelling system
parameters such as future precipitation, temperature, snowfall, and runoff were modeled using precis regionalclimate modeling system in iran with the horizontal resolutions of 0.44×0.44°c in latitude and longitude under sresa2 and b2 scenarios. the dataset was based on hadam3p during the periods of 1961-1990 and 2071-2100. theoverall precipitation error of the model in the period of 1961-1990 w...
Climatic controls on fluvial landscapes are commonly characterized in terms of mean annual precipitation. However, physical erosion processes are driven by extreme events and are therefore more directly related to the intensity, duration, and frequency of individual rainfall events. Climate also influences erosional processes indirectly by controlling vegetation. In this study, we explore how i...
[1] Temperature changes at the Earth surface propagate into the subsurface and leave a thermal signature in the underlying soil and rock. Inversions of subsurface temperature measurements yield reconstructions of ground surface temperature (GST) histories that provide estimates of climatic changes. A question remaining in the interpretation of reconstructed GST histories is the extent to which ...
