This study was conductedin 2016 to see the impact of the jet stream over on
variations the tropical rain in the regionof the Syrian coast,and has daily and monthly
observation of the site by the current virtual movement of the sun, and the accompan
ying
withdrawal of air masses to the surface, causing a state of atmospheric stability,and
therefore studded a private air depressions during the summer half of the year, and studied
each of the geographical location of the regionand the astronomical research of the impact
in the face of Western wind.It was synoptic uppeweather maps r analysis at 200mbr, and
turned out to be the focus of mainstream role in incitementof air masses, and identified the
relationship between the atmospheric pressure values at 200mbr, and the amount of
rainfall, where the relationship is an inverse to the level of the month and quarter and year.
