Abstract
The study examines the cloud cover and its fluctuation and its relationship to atmospheric ozone in Iraq, and accordingly, all types of cloud cover were studied according to octase from 1-8 in four separate regions of Iraq, namely Mosul, Baghdad, Rutba and Basra, in order to give a clear picture of the cloud cover of its types and to find the fluctuation of cloud cover for each type. Reliance on statistical operations* on the general average for each type of cloud cover. The data of the General Authority for Meteorology and Seismic Monitoring in the Ministry of Transport and Communications for the period 1980/1981-1990/1991, starting from September 1980 to August 1991, has been relied upon. As for the cloud cover information for the period 2010/2011-2020/2021 of all kinds, starting from September in 2010 to August in 2021, and thus the study period for both periods is 11 years only, and it was obtained from approved websites ecmwf.int Two tables have been drawn with one page for each study area and for the two periods in order to reduce the number of pages in the research as much as possible and that there are detailed numbers In the analysis, but when drawing the tables, the statistical programs depend on the aspect of approximation to reduce the area of the table by reducing the sizes of cells within the table, and then extracted The average ozone layer rise for the two observations (12z, 00), And then finding the fluctuation in each period and for each observation from the general average, and it was found that there is a decrease in the thickness of the ozone layer in the atmosphere in the selected study areas (Mosul, Baghdad, Rutba, Basra) for the period 2010/2011-2020/2021, when to the average The thickness of the ozone layer in the period 1980/1981-1990/1991, and it was found that there is a decrease in the values of cloud cover for all types of octas and there is no absence of it in the summer months for the modern period of the study than the previous period of the study, and in the month of September it was found that there is an of some types of cover Al-Ghamy in the period 2010/2011-2020/2021, the period 1980/1981-1990/1991, The representation of fluctuations in the figures has been dispensed with in order to be clear and not overcrowded with data and the figure distorted for the reader, and that these recent results may indicate the presence of climatic change in the absence of cloud cover, and accordingly, it may be a door for other climatic studies if the researchers direct them at the present time.
