Abstract
This research paper is about thevariationin the degree of Continentality climate of the Iraq during (40) years for a number of climate station. Using Poresof formula, it is found out that the climate of Iraq ranges between extreme Continentality and very extreme Continentality, and that the Continentality degree is characterized with extreme frequency from one year to another. In certain years, the degree of climate Continentality decreases while in other years it rises in such a way that there is no similarity in the Continental degree from one year to another for the same station. As for the general trend of the degree of Continentality, the last years had noticed special variations, which are divided in to three climate regions: the first region exists in the North and North-East of the country inwhich the Continentality degree tended to decrease and it is ranged between-0.2% to -0.6%,while the Continentality degree of the second region, which is located in the middle and north of the country, tended to rise simply and this ranged between 0.6% to 1.7%. Finally, the Continentality degree of the third region, which is located in the south-east tended to a most clear rise which ranged between 2.5% to 8.7%. By drawing maps of the annual Continentality degree, it is found out that in some yearsthe area of the extreme Continentality climate and the very extreme Continentality climate are equal, while in other years, the area of the extreme Continentality climate becomes much wider and the opposite happens in other years.
