Abstract

The research aims to study the temporal and spatial variations of the frequency of cold waves in Iraq for the period (2000-2005), based on the daily data of daily minimum temperatures for ten climatic stations. The cold wave was extracted using the cold wave threshold as well as the use of hourly weather maps from the Plymouth location, and the results showed In time, the year 2002 was one of the most frequent years of cold waves occurring in the months (January, March, November, December), and the longest wave recorded in the month of March lasted thirteen days, and the center of the groove was over Iraq and Jordan, while the denting was concentrated Over Afghanistan, Turkmenistan, and on the surface high pressure concentrated over Europe and Turkey and low pressure over Saudi Arabia, while spatial variations witnessed a number of cold waves during the study period as the most frequent stations were recorded in the Khanaqin station, and explains the reason for the repeated cold waves affecting Iraq is the frequency of blocks Cold air coming from Europe and Asia.
