أثر المنظومات الضغطية في تراكيز الملوثات الجوية في مدينة البصرة لسنة (2015)‎

الملخص EN

The research deals with the climatic impacts of high and low pressure systems- depending on the analysis of climatic maps of the level (1000) millibar at the day observation 1200 GMT three p.

m Basrah time 2015- on the concentration of air pollutants like (Methane, and methane free compounds, carbon monoxide, nitrogen monoxide, ozone, hydrogen sulfide, sulphur dioxide, carbon dioxide, and the total amount of hydrocarbons) over Basrah city.

It is noticed that the high pressure system helps spreading the concentration of the pollutants and reduce their value.

However, the low pressure system helps accumulating the concentration of the pollutants and increase their value when the Indian seasonal low pressure system helps increase the temperature, decrease relative humidity and air pressure if it is in the center position, when the Sudanese low pressure system reaches it helps decreasing temperature and increasing relative humidity and decreasing air pressure; however, when it is in the stretching status it helps increasing temperature and decreasing relative humidity and increasing air pressure.

The European high pressure system helps decreasing temperature and relative humidity and increasing air pressure.
