A Statistical Analysis of the Geographical and Climatic Variables Influencing the Continentality Degree in Al-Anbar Governorate

الملخص

Continental phenomenon is an essential feature of the climate of the study area, which is characterized by high annual thermal range between (24-25) ° C, low rainfall (58-200) mm per-year and high evaporation values in the summer due to reaching maximum temperatures more than (45) ° C, all this was reflected in the dryness of the region and the dominion of the phenomenon of desertification and thus the destruction of ecosystems and disruption in their balance.

The research aims to show the impact of geographical and climatic factors in the variability of the pattern of geographical distribution of the bituminous degree. The research adopted statistical testing in revealing the most important of those factors affecting this distribution of the six stations, and the results were as the following:

1-All stations recorded a single climatic description, dominated by the very dry continental region according to the Borisov equation, between (72) degrees for Al-Qaim station, located in the far northwest of the governorate, and (76.2) degrees at Al-Nukhaib station located in the south of the governorate.

2- The results of the statistical test showed that the most variable and influencing factors in the phenomenon are relative humidity, wind speed, latitude and the number of clear days with high interpretation coefficients and of significant significance affecting the phenomenon amounted to (81%), (80%), (73%) and (71%) respectively, and with a high correlation strength of (90%), (89%), (85%), and (84%) respectively.
