[ 1 ] - تأثیر دمای سطح آب اقیانوس هند بر تغییرات بارش نیمة جنوبی کشور
در پژوهش حاضر، تأثیر دمای سطح آب اقیانوس هند بر تغییرات بارش نیمة جنوبی کشور با بهره‌گیری از داده‌های ماهانة بارش و داده‌های بازواکاوی‌شده در دورة زمانی 2005-1974 بررسی و توزیع مکانی نابهنجاری بارش در ماههای اکتبر تا مه با بهره‌گیری از روش تابع متعامد تجربیEOF شناسایی شد. سپس مؤلفه‌های اول و دوم مطالعه شدند که 54 تا 7/82 درصد واریانس کل بارش را در ماههای اکتبر تا مه تعیین می‌کنند. در ادامه برا...
[ 2 ] - Analysis of statistics and anomalies of rainfall in Iran during the Warm period(1951-2010)
Investigating the variability of the spatial-temporal pattern of rainfall, which can lead to climate change, due to its strong impact, is of interest to various scientists. For this purpose, after receiving the daily precipitation data of 27 stations for the period of 60 years (2010-1951), its quality and the total monthly precipitation and statistics necessary for the continuation of the resea...
[ 3 ] - Statistical analyzes and anomalies of precipitation in cold period in order to understand the effect of climate change on different regions of Iran (1951-2010)
Investigating of rainfall behavior in the spatial-temporal dimension and determining the tolerance thresholds of different geographical areas with respect to vegetation, animal life and human activities, is essential for any decision in the environment. Therefore, precipitation data of 27 stations were received from the Meteorological Organization during the 60-year period and After the data we...
[ 4 ] - Simulation of rainfall temporal distribution pattern using WRF Model (case study of Parsian dam basin)
During the rainfall, the intensity of precipitation varies. Changes in the amount of precipitation during an event of rainfall are effective in the resulting of flood and its intensity. Knowledge of how rainfall changes over time during rainfall is determined by temporal distribution pattern of rainfall. For this purpose, availability of short-term time scales rainfalls data are important that ...
