Study of the relative change of ozone values in Baghdad

Abstract

Abstract:

      Climatology is one of the applied sciences that we rarely find a competitor in in the field of its close connection with human life and the various manifestations of its activity, as it is one of the main factors affecting the life activities of various living organisms, and therefore it enables researchers to understand and explain various vital phenomena after understanding their surroundings, and thus develop strategies  It serves as a safeguard for the environment from the danger of deterioration and pollution, and then it has preserved normal life.  The research aims to determine the total ozone values   in Iraq, through the use of statistical methods and the selection of the most important methods through which the ozone can be calculated in the study area, and thus analyze the relative change in the study area. This research was applied in the station (Baghdad), so it will be done in this  The chapter is based on the use of the general trend method and the relative rate of change in order to clarify the changes occurring in the ozone values   in the study area, and to reveal the general trend and rate of change in the study area (Trend Detection).  The trend coefficient as a percentage of all the variables in the climate elements, as well as for the annual rates of change) according to the following equation:.

 whereas :

 

c = annual relative rate of change*

 bi = trend coefficient

 y = arithmetic mean

 (**bi) can be extracted from the following equation:

 

  2- 1=Difference between the two means

 T2-T1 = difference between the two times
