Abstract: 

In this paper, atmospheric circulations caused by airflow over mountains and hills with different experimental setups are investigated. It is known that in a stable atmosphere the airflow over wide mountains makes the air parcels move in a wave like pattern in the vertical plane. First, the steady state of the momentum equation in the zonal and vertical directions, the thermodynamic and continuity equations are linearized, neglecting friction and rotation. Then combining the linearized equations into a Helmholtz type equation for the vertical velocity, W (or stream function,) is solved using the Fourier transform method. The experiments are performed for one and two isolated mountain peaks with different heights and varying horizontal velocity and Scorer parameter using a one and two layer models. Results show that, if the Scorer parameter is larger in the lower layer then the airflow follows the shape of the mountain and associated troughs and ridges are deeper with increased mountain height and horizontal wind speed. Moreover, ascending and descending vertical motions are formed in the mountain side and leeward side with their cores located at around 3 km altitude. Their amplitudes are extended to higher levels up to 10 km.

Abstract: 

The Shotori mountain range at northern end of the Nayband active fault is one of the east central Iranian ranges in east of Tabas city and playa. Old alluvial cyclic stream terraces and buried Quaternary fault scarps in western mountain front area, and three kind of old, braided, and active alluvial fans in Tabas plain are witnesses to mountain neotectonic uplift, westward migration of Quaternary sedimentation, and eastward movement of retrograde erosion along seasonal rivers. Ancient perched caves and qanats in alluvial valley slopes present the speed of deep erosion.Outcropped Neogene anticlines, old erosional terraces, meandring antecedent river gorges, and warping of the old fans in Tabas plain all point to periodic active uplift of the plain with respect to the playa. Geomorphic indices, such as knickpoints in longitudinal river profile, valley width/heigth ratio, and mountain front sinuosity show that the active tectonic movements are due to the Quaternary faults in the Tabas plain and along northern and southern parts of the moimtain front, but the middle front seems to be inactive in the present time.Meanwhile, the 1978 earthquake of Tabas (Ms=7.3) after an 11-century seismic gap is a proof to the active westward migration of the deformational front. In this way, the close relationships between the tectonic geomorphology of the area and the seismotectonics of the recent earthquake led us to introducing relic, inactive, active, and new-born mountain fronts in the area; and the role of such studies in better undrestanding of activity and seismicity history of regions is emphasized.

Abstract: 

کوهستان شیرکوه در مرکز استان یزد واقع شده که به وسیله نواحی گرم و خشک احاطه شده است. موقعیت جغرافیایی این منطقه موجب ایجاد اکوسیستمی بسیار حساس گردیده که پوشش گیاهی آن نقش مهمی در معیشت مردم اطراف دارد. در مطالعه حاضر با استفاده از نمونه گیری ها، داده های اقلیمی و نیز تصاویر ماهواره ای، رابطه ی میان تغییرات دما (به عنوان شاخص اقلیم) و تغییرات میزان پوشش گیاهی در دو ماه گرم و سرد برای منطقه به دست آمد. نتایج نشان داد که در ماه آوریل از دمای کم به دمای زیاد میزان NDVI افزایش می یابد و در در ماه ژوئن تا دمای 11 درجه با افزایش دما، میزان NDVI افزایش یافته و پس از آن کاهش می یابد. از نتایج این مطالعه می توان اینگونه استنباط کرد که تغییرات NDVI تیپ های گیاهی یکسان در ماه های مختلف سال با افزایش ارتفاع و تغییر طبقات دمایی بین رویشگاه های سرد و گرم در یک منطقه ی کوهستانی می تواند تحت تاثیر افزایش دمای محیط کمتر شود.
