Behavior of the Total Column Ozone and Temperature above Iraq during 2012 Strong Geomagnetic Storms

Zahra T. I., Najat M. R. Al-Ubaidi

Abstract: The aim of this research is to investigate the behavior of the Ozone layer through the total column Ozone (TCO) during the strong geomagnetic storms of the year 2012 and to find the effect of the geomagnetic storms on the variation of the temperature (T2m) two meter above the Earth surface by studying the hourly variations, daily average and monthly average of these two parameters above Iraqi region (38- 49N, 28-38E), The data of (TCO) and (T2m) were selected from the ERA satellite for year 2012, in which there are seven strong geomagnetic storms occurred along five months. Drawing the monthly and the daily average (two days before, stormy day, and seven days after the stormy day for three Iraqi cities Muthanna, Baghdad, and Sulaymaniyah). From monthly average the results reveals that the thickness of Ozone layer in North of Iraq wider than the Middle and South of Iraq for all stormy months except in October of 2012 appears that the maximum in Middle of Iraq. About the temperature it is reversely preoperational with Ozone thickness. The maximum values of TCO in spring it reaches 327 DU in April. From the hourly variations of TCO and T2m for three Iraqi cities, it seen that in some events it is decreases and others increases do not depend on storm type, utmost it is increases. The slope of trend line for variation of (TCO) with the variation of (T2m) drawn gives that there is no relationship between them along the three cities taken and for all events.
