امروزه پدیده ی تغییر اقلیم به عنوان یک معضل جدی گریبان گیر کشورهای جهان شده است، به نظر می رسد که اکوسیستم ها به طور ویژه ای از این تغییرات آسیب بینند، از این رو مطالعه ی روند تغییرات متغیرهای اقلیمی در درازمدت اهمیت ویژه ای در بررسی های اقلیمی و پیش بینی آن در آینده خواهد داشت. پدیده ی بارش تابع عوامل زیادی می باشد که پیش بینی آن به روش های معمول آماری از دقت کمی برخوردار است. روش های مختلفی ب...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
flood is one of the most calamitous natural disasters that causes extensive property and life damages across theworld. it however, could be a blessing due to its special natural water resources recharging value. by simulating themagnitude of probable floods considering the anthropogenic and natural effects and implementing contingency plans,their damages could be reduced. in this paper, the gen...
We analyse the response of the TIE-GCM computer model of the upper atmosphere to atmospheric tides at its lower boundary and to variations of night-time ionization rates. TIE-GCM is an expensive code, and we choose to use our thirty evaluations of the model to construct an emulator, and then use the emulator for the analysis. TIE-GCM has some non-standard features, namely a periodic input, and ...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
Concern about the impact of climate change on natural and socioeconomic systems has been increased in recent years and this issue caused an increasing interest in the scientific community . The aim of this study is to evaluate changes in parameters such as precipitation, minimum and maximum temperature by General Circulation Models (GCM) and its impact on average runoff using SWAT model in Gh...
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...

The authors propose a simple theory to explain a climatic drift previously found in a series of coupled general circulation model (GCM) experiments. Their theory places the GCM results on a simple stability diagram for the thermohaline circulation in the Atlantic. It is argued that the drift is due to Stommel’s salt advection feedback and arises because the particular spinup procedure of the co...
