  • Spatial analysis and investigation of Tele-connection patterns with drought in central Iran 

    فاطمی, مهران؛ امیدوار, کمال؛ مسگری, ابراهیم؛ نارنگی فرد, مهدی (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2016-12-21)
    This study, adopting an environmental approach to atmospheric circulation, estimates drought periods over a 20-year period (1992-2011) in 21 synoptic stations in Kerman, Yazd and Isfahan provinces, which share a long-term ...

  • Self-Consistent hot spot tracing particles by kinetic simulations: With the emphasis on Cusp particle entry 

    کلایی, محمدجواد؛ اسماعیلی, امین (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2016-12-21)
    One of the most important advantages of particle simulation as compared to fluid simulation is the capacity for working with and tracing particles. In particle simulations, the test particle method is usually used to get ...

  • On the source of plasma density and electric field perturbations in PMSE and PMWE regions 

    محمودیان, علیرضا؛ Mohebalhojeh, Alireza؛ مزرعه‌فراهانی, مجید؛ Scales, Wayne (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2016-12-21)
    تشکیل ابرهای مسسفری در فصل تابستان و در ارتفاع ۸۰ تا ۹۰ کیلومتری از سطح زمین در نواحی قطبی دارای اهمیت بسیار زیادی می باشند. ارتباط مستقیم بین افزایش مشاهده این ابرها و پدیده گرم شدن کره زمین از دلایل اصلی اهمیت مطالعه این ...

  • Optimizing design of 3D seismic acquisition by CRS trace interpolation 

    ُSoleimani, Mehrdad؛ Roshandel Kahoo, Amin (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2016-12-21)
    Land seismic data acquisition in most of cases suffers from obstacles in fields which deviates geometry of the real acquired data from what was designed. These obstacles will cause gaps, narrow azimuth and offset limitation ...

  • Evaluation of Groundwater Vulnerability Using Data Mining Technique in Hashtgerd Plain 

    Javadi, Saman؛ Hashemy, S. Mehdy (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2016-12-21)
    Groundwater vulnerability assessment would be one of the effective informative methods to provide a basis for determining source of pollution. Vulnerability maps are employed as an important solution in order to handle ...
