[ 1 ] - برآورد میانگین روزانه دمای خاک در چند نمونه اقلیمی ایران با استفاده از داده‌های هواشناسی
Soil temperature is one of the important variables in hydrology, agriculture, meteorology and climatology studies. Owing to the fact that soil temperature is only measured at synoptic stations, reconstruction of this variable in other places is of great importance for many relevant agricultural surveys. Using 10-year (1996-2005) daily meteorological observations, including: air temperature, glo...
[ 2 ] - ارزیابی حساسیت مدل‌های مختلف تبخیر- تعرق مرجع (ETo) به سیگنال‌های تغییر اقلیم در اقلیم سرد نیمه خشک همدان
Under different climatic conditions of Iran, the evaluation of evapotranspiration (ETo) models sensitivity to meteorological parameters, prior to introducing the superior performance model, seems quite necessary. Using a 35-year (1971-2005) climatological observations in Hamedan, this study compares the sensitivity of different commonly used evapotranspiration models to different meteorological...
[ 4 ] - ارزیابی روند احتمالی تغییرات اختلاف دمای شبانه‌روزی در برخی اقلیم‌های خشک کشور طی پنج دهه گذشته
Climate is an important and determinning factor affecting many agricultural products. Diurnal temperature range (DTR) is an effective parameter in assessing climate change impacts on environment in a region. This parameter is determined by the difference between minimum and maximum air temperatures. In this study, changes in the daily DTR collected from 11 synoptic stations were analyzed. The s...
[ 5 ] - ارزیابی دقت روش‌های شبکه عصبی مصنوعی و عصبی- فازی در شبیه‌سازی تابش کل خورشیدی
Solar radiation is an important climate parameter which can affect hydrological and meteorological processes. This parameter is a key element in development of solar energy application studies. The purpose of this study is the assessment of artificial intelligence techniques in prediction of solar radiation (Rs) using artificial neural network (ANN) and adaptive neuro-fuzzy inference system (AN...
