The results of this study indicated that the synoptic patterns that lead to heavy rainfall in 22 March 1996, 24 mar 1995 and 17 November 1994 in the northern portion of FARS province includes: the low pressure that located in eastern part of Mediterranean and Black sea and southern part of Caspian Sea that created by trough that located at the middle level of atmosphere. In addition to this low...
in this research, for synchronization analysis of black sea high pressure with daily precipitation in iran data base have been created with using the sea level pressure data in reanalysis ii database in national centers for environmental prediction(ncep)/national center for atmospheric research(ncar). temporal resolution of data is daily and spatial resolution is 2.5 ã 2.5 degrees of arc. fram...
[1] Over the past fifty years, December–February mean sea level pressure has decreased markedly over both poles, corresponding to a trend toward strengthened westerlies in both hemispheres. In this study we compare observed sea level pressure trends with those simulated in response to natural and anthropogenic influence in a suite of eight upto-date coupled general circulation models. A global ...
the areas of the world that have mediterranean style climate are found at about 35 degrees north and south of the equator, on the western sides of continents. the distinctive feature of this climate is the small amount of rain in the summer. overall, the climate has a moderate amount of rainfall and warm winters and hot summers and. the climate of the mediterranean region is conditioned by its ...
1. To assess the effects of acute exposure to high altitude on baroreceptor function in man we evaluated the effects of baroreceptor activation on R-R interval and blood pressure control at high altitude. We measured the low-frequency (LF) and high-frequency (HF) components in R-R, non-invasive blood pressure and skin blood flow, and the effect of baroreceptor modulation by 0. 1-Hz sinusoidal n...
Climate control centers in each area are diverse and understanding how they relate to the atmospheric components of the Earth's surface contribute to prediction of climate fluctuations. In this study, by using Pearson's correlation and multivariate regression in a thirty-year period (1961-2010), the relationship between widespread rainfall anomalies in entire of Iran west with temperature a...
[1] Sea level in the Mediterranean Sea over the period 1993–2011 is studied on the basis of altimetry, temperature, and salinity data and gravity measurements from Gravity Recovery and Climate Experiment (GRACE) (2002–2010). An observed increase in sea level corresponds to a linear sea level trend of 3.0 0.5mm/yr dominated by the increase in the oceanic mass in the basin. The increase in sea le...
abstract this research attempts to investigate the role of the blocking systems in surface cyclogenesis over eastern mediterranean sea; but particular attention is focused on the flood of iran during march 2000 over western states of iran as: hamadan, ilam, lorestan, kermanshah, kurdestan, zanjan, ghazvin.the data used for this research includes upper level and mean sea level pressure charts ev...
