The impact of climate change on the number of days of survival of the phenomenon of freezing in Iraq for the period from 1968-2021

Abstract

The research revealed a trend towards a decrease in the rates of the number of days of freezing phenomenon, as the highest rates were recorded in January, while the lowest rates were recorded during April during the study period. The highest and lowest rates of change were during December, as the Mosul station recorded the lowest positive change rate amounted to (+0.16%), while the highest negative change rate was recorded in Basra station, which amounted to (-63.01%). In the fifth climatic cycle, as for the seasonal change rate, the Basra station recorded the highest negative change rate, amounting to (-29.01%), at the same time, the Mosul station recorded the lowest negative change rate, amounting to (8.14 %). In the northern stations, it can be said that the number of days of the freezing phenomenon began to decrease in general, and this is due to climatic changes that in turn affected the elements of the climate, specifically the temperatures, and this was reflected in cases of low temperatures (0 m and below(.
