introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...
For the first time in metcorological history the broad aspects of the southerly low-level jet o\er the Western Plains have been studied in fine detail both in time and space. This as acconiplished in the spring of 1961 by means of a line of 13 pibal stations established between Amarillo, Tex., and Little Rock, Ark. Twenty-five consecutive hourly observations were taken at each station on a tota...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
Background and Aim: Autotoxic substances such as JP-4 jet fuel can have negative effects on the auditory system by the various means such as cochlear dysfunction. The purpose of this study was to investigate the combined effects of exposure to JP-4 jet fuel and noise on hearing loss in rats, to determine the possible interference effects of these two risk factors on rat auditory system. Methods...
Rossby Wave Chromatography (RWC) is implemented in a linearized barotropic model as a tool to understand the response of the mid-latitude jet to external forcing. Given the background zonal-mean flow and the space-time structure of the baroclinic wave activity source, RWC calculates the space-time structure of the upper tropospheric eddy momentum fluxes. RWC is used to diagnose and understand t...
