This piece of research analyzes the general-index change of annual medium temperatures in some stations of the Syrian Coast during the years 1970-2010, so as to identify the amount of change in temperatures and the effect of such a change on the prob
able density that results in annual medium temperatures that are both extreme and unnormal.
Results point to an increase in temperatures in all those stations between 0.8 and 2 Celsius degrees. This increase is significant statistically. At the same time, temperatures had not gone lower than their general average in all those stations during the first decade of the 21st century, contributing to an increase of the annual average of temperature during the years 2001-2010 in comparison with the years 1970-2000.
Using Natural Distribution Diagram during the years 2001-2010, analysis of the probable density of temperature refers to a great increase in the possibility of having higher extreme temperatures whose value did not exceed 5% over the last three decades. By contrast, lower extreme records had zero probability and got higher than they had been during the three decades of the late century.
Due to the importance of climate changes and their strong and increasing influences
on different human and ecological systems, It is necessary to study and understand these
changes. This research aims to determine the direction and magnitude of the
change in
temperatures and rainfall trend during 1978-2011 in Latakia, Kasaab and Slenfeh. The
study has been done through the analysis of annual, seasonal, and monthly rainfall amount
and temperature average, which showed a significant increasing in the average annual
temperature in the three regions and significant seasonally increasing except for Winter in
Latakia and Slenfeh, Autumn in Latakia. But the annual rainfall changes were nonsignificant,
while seasonally rainfall increased significantly in Slenfeh Winter and
decreased in Kasaab Winter. After dividing the entire study duration into two equal periods
1978-1995, 1995-2011 and comparing the second period with the first one, we found a
significant increasing in the average annual temperature in the three regions,
non- significant in the annual and seasonal rainfall changes. The highest significant in
seasonal temperature in Latakia, Kasaab and Slenfeh reached +1.5, +2.9, +1.8 during
September, August، and May respectively. While the annual drought showed increased
trend in Latakia and kasaab and decreased one in Slenfeh.
