the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
Ectotherms, such as insects, experience non-constant temperatures in nature. Daily mean temperatures can be derived from the daily maximum and minimum temperatures. However, the converse is not true and environments with the same mean temperature can exhibit very different diurnal temperate ranges. Here we apply a degree-day model for development of the grape berry moth (Paralobesia viteana, a ...
Site-specific and accurate prediction of daily minimum air and grass temperatures, made available online several hours before their occurrence, would be of significant benefit to several economic sectors and for planning human activities. Site-specific and reasonably accurate nowcasts of daily minimum temperature several hours before its occurrence, using measured sub-hourly temperatures hours ...
As an intrinsic feature of daily surface air temperature (SAT) variability found in station measurements, temporal asymmetry (TA) can be taken as evaluation metric to access the quality SAT re-analysis product. In this study, TA calculated from four variables, i.e., mean (Tmean), maximum (Tmax), minimum (Tmin) and diurnal range (TDTR = Tmax − Tmin), is applied evaluate synoptic-scale performanc...
abstract long-term historical weather data are needed to conduct crop simulation analysis. simulated climatic data may be used when long series of historic data are not available or convenient or when future data are needed. the aim of this study was to generate daily weather values for maximum and minimum air temperatures. a number of weather generators are compared here. data from ten station...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
Abstract. Near-surface air temperature (Ta) is an important physical parameter that reflects climate change. Many methods are used to obtain the daily maximum (Tmax?), minimum (Tmin?), and average (Tavg) temperature, but affected by multiple factors. To Ta data (Tmax?, Tmin?, Tavg) with high spatio-temporal resolution in China, we fully analyzed advantages disadvantages of various existing data...
The use of land surface temperature and vertical temperature profile data from Moderate Resolution Imaging Spectroradiometer (MODIS), to estimate high spatial resolution daily and monthly maximum and minimum 2 m above ground level (AGL) air temperatures for regions with limited in situ data was investigated. A diurnal air temperature change model was proposed to consider the differences between...
This paper presents a comprehensive analysis of the effect urbanization on surface air temperature (SAT) from 1951 to 2018 in Philippines. The daily minimum (Tmin) and maximum (Tmax) records 34 meteorological stations were used derive extreme indices. These then classified as urban or rural based satellite night-lights. results showed significant difference SAT trends between stations, indicati...
Defined as the difference between daily maximum (Tmax) and minimum surface air temperature (Tmin), diurnal range (DTR) is critical to local climate, ecosystem, socio-economic functioning. This study investigates how DTR responds future global warming, using a novel, fine-resolution convection-permitting regional climate model. Results demonstrate asymmetrical impact of that is, more substantial...
