in this research the temporal-spatial changing trend of nightly temperatures in isfahan province has been studied with the purpose of manifesting temperature changes, recognition of temperature abnormality and comparison for the two methods of pixel and station. on this basis, the data of the minimum temperature average of 21 synoptic and climatology stations were processed in the said province...

abstract the temperature of water entering the soil or variation in soil temperature has a direct impact on soil hydraulic conductivity via the effect on water viscosity. in this research, the time variability of soil saturated hydraulic conductivity (ks) was studied. the relation between soil temperature and fluid viscosity with hydraulic conductivity were also studied. the necessary experimen...

Using clim ate records from 20 weather stations, we investigated the changes in temperature, rainfall, and length of the growing season between 1961 and 1995. To establish a link between changes in climate and tree growth, we analyzed radial increment rates from tree rings over the same period. Our results indicate: (1) no change in precipitation over the period; (2) a highly significant increa...

This study presents a comprehensive assessment of the variability and trends of the precipitation and temperature along with the trends in drought indices over the State of California. The non-parametric Mann–Kendall trend test is applied with a trend-free pre-whitening procedure in trend identification. A dataset containing 120-year (water years 1896–2015) monthly precipitation, average temper...

BACKGROUND The minimum mortality temperature from J- or U-shaped curves varies across cities with different climates. This variation conveys information on adaptation, but ability to characterize is limited by the absence of a method to describe uncertainty in estimated minimum mortality temperatures. METHODS We propose an approximate parametric bootstrap estimator of confidence interval (CI)...
