Although recent studies have examined the responses of annual- and seasonal-mean Madden-Julian oscillation (MJO) activity to global warming, little is known about seasonal cycle changes that determine timing peak MJO influence on local weather climate. By analyzing Community Earth System Model version 2 large ensemble at end 21st century, we report in both phase amplitude precipitation over tro...

Changes in the Madden-Julian Oscillation (MJO) with increasing CO2 concentrations are examined using the Goddard Institute for Space Studies Global Climate Model (GCM). Four simulations performed with fixed CO2 concentrations of 0.5, 1, 2, and 4 times preindustrial levels using the GCM coupled with a mixed layer ocean model are analyzed in terms of the basic state, rainfall, moisture and zonal ...

In this paper, we report the triggering effect of extratropical perturbation on the onset of an atypical Madden-Julian Oscillation (MJO) and onset of the 2015-16 El Niño in March 2015. The MJO exhibited several unique characteristics: the effect of extratropical forcing, atypical genesis location and timing in the equatorial western Pacific, and the extremity of amplitudes in many aspects. The ...

The land-sea surface temperature contrast on the western coast of Sumatra Island was examined using observation data obtained from the pre-Years of the Maritime Continent (YMC) field campaign from November to December 2015. Surface observations showed that, on most days, strong daytime solar radiation caused a pronounced diurnal cycle in surface air temperatures on the island, even during the l...

in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

Abstract The Madden–Julian Oscillation (MJO) is the dominant mode of intraseasonal variability in tropics and has a documented influence on extratropical extreme weather through modulation synoptic atmospheric conditions. MJO phase been correlated with anomalous tornado severe hail frequency United States (US). However, robustness this relationship unsettled, physical pathways to poorly underst...

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 ...

Introduction: Exploratory behaviors in rodents are an indicator of anxiety behaviors. In the present study, the combined effect of aerobic exercise with different intensities and inhibition of the glutamate system on exploratory behavior in rats was investigated. Materials and Methods: In this experimental study, 80 male Wistar rats were randomly divided into 10 groups including control, diazep...

انگیزه بنیادین این پژوهش آن است تا روشن سازد همزمانی و هماهنگ شدن فازهای گوناگون پدیده‌‌های نوسان‌های مادن جولیان (MJO)1 و نوسان‌های جنوبی (ENSO)2 تا چه اندازه در رویداد دوره‌های پر آب و خشک کشور سایه می‌افکند. ارزیابی‌ها نشان داد که رخداد همزمان لانینیا با فاز مثبت MJO (La-P) و نیز النینیو با فاز منفی MJO (El-N) دارای بیشترین بسامد می‌باشند. بنابراین اندازه بارش و بسامد د...
