Investigating the Meteorological Drought Using CZI in Nineveh Governorate, Iraq.

Abstract

This paper deals with the study of drought in the Nineveh region using
the Chinese Z index (CZI) for a time scale (1 month). Historical data were
used from 1981 to 2018 for Mosul, Sinjar, and Tal Afar stations. The
return period and probability event for the moderate drought were
calculated for each month separately. The results indicated that all
stations experienced the highest drought intensity in March compared
with the other months. The average probability of moderate drought
ranged between 0-0.31 for all months, and the maximum severity of the
drought was found in December from 2004 to 2008 for all stations. In
addition, the results showed that the region's climate during the study
period was within the mild drought and humidity (closest to normal).
This paper is the first study using the Chinese Z-index (CZI) in the study
area and the Iraq region
