  • On the Relation Between the Large-Scale Tropospheric Circulation and Air Quality in Tehran 

    Hafezi, Mojdeh؛ Mohebalhojeh, AliReza؛ Aliakbari-Bidokhti, Abbas Ali؛ Irannejad, Parviz؛ Sabetghadam, Samaneh (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2017-12-22)
    The large-scale tropospheric circulation can play a controlling role in the accumulation and ventilation of air pollutants. It thus impacts air quality in large urban areas. This paper investigates the statistical relations ...

  • Trends of Extreme Temperature Over the Lake Urmia Basin, Iran, During 1987-2014 

    Azizzadeh, Mohammadreza؛ Javan, khadijeh (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2017-12-22)
    The variability of temperature extremes has been the focus of attention during the past several decades and had a great influence on the hydrologic cycle. A long-term, high-quality daily maximum (TX) and minimum temperature ...

  • A Study of Bit Condition for Generation Rx -Mode Waves: Interaction of Particles with Z/UH-Mode Waves 

    Kalaee, Mohammad Javad (موسسه ژئوفیزیک دانشگاه تهرانInstitute of Geophysics, University of Tehran, 2017-12-22)
    Interactions of charge particles with electromagnetic waves have important effects (linear and nonlinear) on the propagation of electromagnetic waves, and it can somewhat play a role in generation of the new mode waves. ...
