Results of assessment of the future climate change impacts is associated with some uncertainties. Considering the range of uncertainties increases reliability of the results. In this study, climate change impacts on daily precipitation, maximum and minimum temperature of Sira basin are assessed using LARS-WG model, for 2036-65 period. Accordingly, uncertainty of new emissions scenarios (RCP2.6،...

An AO is an example of teleconnection pattern in the northern hemisphere’s winter. In this study, the effect of AO on the monthly minimum temperatures in the North-East region of Iran is investigated. The required statistics, including statistics monthly minimum temperatures for 17 synoptic stations of the under study area was provided from Iran Meteorological Organization’s (IRMO). Pearson cor...

The relationship between the seasonality of ischaemic heart disease (IHD) mortality and temperature is explored for the purpose of evaluating the climate-based predictability of the magnitude and timing of the annual IHD mortality peak for 5 English counties. Seasonality is described by the amplitude (magnitude) and phase (timing) of the first harmonic of the annual cycle of IHD mortality and m...

A thorough understanding of thermal soil regimes is critical information for a wide variety of disciplines and engineering applications as well as for the evaluation of potential and limitations of thermal and optical sensors. In this study we have developed a procedure for the evaluation of global thermal soil regimes. First, pedotransfer functions are used to derive thermal soil properties (v...

We developed an innovative methodology for the reconstruction of MODIS Land Surface Temperature (LST) time series, and derived temperature indicator maps to describe the potential distribution areas for the invasive tiger mosquito Aedes albopictus, a vector of several human diseases. The distributional limit of this species in temperate areas is determined by a minimum January mean temperature ...

This study investigated seasonal changes in density and diversity of phytoplankton, chlorophyll a content, and some environmental characteristics in the Sistan region during 2014. Totally, we detected 28 genera that belonged to five groups of Chlorophyta (12 genera), Bacilloriophyta (7 genera), Cyanophyta (5 genera), Dinophyta (3 genera), and Euglenophyta (1 genus). We observed that Chlorophyta...

Thermal modelling and optimal design of a solar absorption cooling system are presented, and hourly analysis is performed over the period of a year. Three design parameters are considered, then the Real Parameter Genetic Algorithm (RPGA) is applied to obtain the minimum total annual cost. The optimization results show that the solar cooling optimum configuration needs 1630 square meter collecto...

The inter-annual and inter-decadal variation of temperature in Dabie Mountain West Anhui Province is analyzed according to actually measured data daily average temperature, maximum minimum during 1960-2013 five meteorological stations Mountain. Results show: quarterly annual (except the summer) are all a rising tendency. increases remarkably at an amplitude 0.165°C/10 years. increase 1-2 times ...
