تحليل الكثل الهوائية على كمية الغبار المتساقط في محافظة ديالى خلال مدة (2016-2017)‎

Abstract EN

The study of air masses is of the important geographical studies4 it is one of the surface climatic phenomena that affect the environmental aspects related to climatic conditions and determine air pollution.

The study discussed five district (Baqubah Bany Saad‘ Baladrooz‘ Khanaqeen and Khalees) in Diyala province.

The study considered the dust deposited from the Directorate of Diyala Province Division for the years 2016 and 2017 and the climatic data of the two pressure levels (sea level and 500 milligrams) of the General Organization for Aeronautics and Monitoring Seismic data indicated that the amount of dust deposited for 2016 more than the amount of dust deposited for the year 2017, and the rate of a tmospheric pressure less than 2017‘ which means the control of the low atmospheric pressure system in 2017 and the maximum temperature for the month of January and February and March and October For the year 2017 and the humidity for the month of December and October ‘ and less than the equivalent of 2017, and the rain for the month of May 2016 was less rainfall than the equivalent of 2017.

The study also analyzed the highest and lowest value of the deposited dust in the two mentioned years4 which were for the months of July and January 2016, and for June and April 2017‘ the first two axes are the synoptic axis‘ (500 mb).

The increase in dust and precipitation increased with the increase in temperature and dryness of the air mass‘ which led to an increase in the contour height of the maps.

The lack of dust deposited coincided with the dominance of the high altitude system ‘ while the maps of (500) T decrease dust deposited with low temperature air mass temperature and humidity increase4 which led to a decline in contouring maps rise.

Also included the correlation between precipitation and temperature (maximum, micro4 normal), relative humidity, precipitation, wind velocity and atmospheric pressure using the Excel program was found to be positive with temperature of all kinds.

The coefficient of correlation in 2016 was 0.85‘ and in 2017 was 0.53.

While with relative humidity the inverse relation was recorded (- 0.80)‘ and the wind speed (-0.11) (-0.45).

Resulting in the necessary measures to reduce them and increase the efficiency of cultivated areas to 90-80% ‘ which reduces the exposure of the province to the dangers of air pollution and the establishment of bumpers for wind and the establishment of the green belt.
