The relationship between high-pressure systems and concentrations Carbon dioxide gas in the city of Kirkuk For the climate cycle (2011-2022

Abstract

One of the most important problems facing humans and their environmentAnd the most prominent of themFrom ancient times to the present day, climate change, with all its elements and phenomena, has been a constant.KhIt deals with human problems and various activities; therefore, studying climate change and its effects is a vital and essential field that has captured the attention of scientists, whether climatologists or others. The atmosphere is a crucial and fundamental part of life, and it consists of a mixture of homogeneous gases that disperse and concentrate solid and gaseous pollutants.Its effectThe emission (concentration or spread of surface air pollutants is linked to the overall upper system, and then gaseous and particulate air pollutants are drawn in) is related to the characteristics and phenomena of the (overall) atmosphere.

This study aims to analyze the impact of high-pressure systems on air pollutant concentrations in Kirkuk, as these are key factors affecting the activities of living organisms. The researcher relied on data and information from NASA's Surface Weather Forecasts website for the period (2011-2022), using statistical methods and selecting the most important methods for calculating carbon dioxide levels.CO2 levels in the study area were analyzed, and the relative change in these levels was applied to the Kirkuk station. Therefore, this research will utilize the general trend and relative change methods to illustrate the changes occurring in CO2 levels in the study area, to reveal the general trend and rate of change, and then to express the trend coefficient as a percentage. The study concluded that:

1- The highest temperature recorded during the climate cycle (2011-2022) was in January (4.179ppmDuring the 2021-2022 season, the lowest-scoring month was November.3.94ppm) in the (2012-2013) season.

2-During the climatic cycle (2011-2022), the highest average concentration of carbon dioxide at the Kirkuk station was observed during the month ofMays reached (4.075ppm)And the lowest rate during the monthIn September and November, it reached (4.022ppm).

3- During the climate cycle (2011-2022), the relative change in concentrations reached Carbon dioxide is the highest concentration of carbon dioxide in Kirkuk power plant this month.October (26.44%)Less than a monthSeptember (0.49%4)All months recorded a positive trend.

4- High pressure systems have a clear effect on the concentration of carbon dioxide pollutant in the study area. It was found that they had a positive effect on the concentration of that pollutant in all months of the year except for some months that recorded a negative effect. This explains the increase or decrease in concentrationsCarbon dioxide gas pollutant, where the explanatory coefficient varied between pressure systems on the one hand and between months on the other..

5-It is observedThe highest impact in the caseHigh EuropeanextensionExistence with a direct correlationstrongbetween High EuropeanCenter and focusCO2, which reached 0.78, according to the interpretation factor (R2=0.62) This explains why the system contributes to (62%) of the changes that occur to CO2 gas, and the remaining percentage of (38%) is due to other variables..
