Abstract    This paper aims to predict the periodic variation of ground temperature with depth for time variant condition of ambient air temperature and solar radiation data for Jamshedpur, India. Fourier series and numerical techniques have been used to determine (hottest and coldest day) diurnal and annual temperature variation of the year 2015. The diurnal temperature variation is up to 0.2 m depth of soil whereas annual temperature variation is up to 3 m depth.


Keywords    Soil temperature; Numerical ; Fourier series


چکیده    هدف از این مقاله پیش بینی تغییرات دوره ای دمای زمین با عمق برای شرایط مختلف دمای هوا و داده های تابش خورشیدی برای جمشیدپور، هند است. سری فوریه و تکنیک های عددی برای تعیین دمای روزانه و سالانه داغترین و سردترین روز سال 2015 استفاده شده است. تغییرات دما روزانه تا عمق خاک 0.2 متر است در حالیکه تغییرات دما سالانه تا عمق 3 متر است.
