Experimental data were applied for the modelling optimal cowshed temperature environment in laboratory test bench by a mass-flow method. The principal factor affecting exponent growth of ammonia emission was increasing air and manure surface temperature. With the manure temperature increasing from 4°C to 30°C, growth in the ammonia emission grew fourfold, that is, from 102 to 430 mg m(-2)h(-1)....

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...

We simulate the effect of climate change on water requirements of cold seasonwheat in various climatic zones of Iran. The research considers both observedclimate (temperature and precipitation) changes during recent decades (1960-2009)based on instrumental records and projected future changes to 2100 based on theMAGICC/SCENGEN 5.3 compound model. 20 General Circulation models are usedbased on a...

Trends in short-lived high-temperature extremes record a different dimension of change than the extensively studied annual and seasonal mean daily temperatures. They also have important socioeconomic, environmental, and human health implications. Here, we present analysis of the highest temperature of the year for approximately 9000 stations globally, focusing on quantifying spatially explicit ...

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.

[1] We construct an extratropical reduced temperature–depth profile for land areas north of 20 N latitude from the global borehole temperature database compiled for climate reconstruction. The mean reduced temperature profile compares well with a time series constructed from an initial baseline temperature (0.6 ± 0.1 C) and the last 140 years of gridded annual surface air temperature data diffu...

The Mangla reservoir was built for irrigation as well as power generation. The variability in climatic variables (temperature and precipitation) at spatial and temporal scales affects the streamflows. To consider the hydro-climatic unpredictability, 50 years (1961-2010) record was scrutinized. The time series were divided in two periods of 25 years each (1961-1985, 1 and 19862010, 2). Results o...

The soil climate data has been collected during a recent biocomplexity study along a bioclimatic gradient in the North American Arctic Tundra. The measurements were made from South to North at: Happy Valley, Sagwon Hills, Franklin Bluffs, Deadhorse, West Dock, Howe Island, Green Cabin, Mould Bay and Isachsen research sites. Mean annual air temperature changes from around –10°C at the Happy Vall...
