Abstract
The current study aims to determine the dry seasons north of the °35
latitude in Iraq using the standard precipitation index (SPI) standard,
which defines and classifies the dry and wet seasons during the seasons
(fall, winter, spring) and (rainy season) (D) using the CROP WAT
program, through which the climate of the study area is classified
according to the Monthan Banean budget, as well as the general trend of
drought according to the drought coefficient (D).
The study relied on the data of the monthly averages of rainfall for
nine climatic stations distributed over the study area geographically
and for( 35) seasons for the period (1979-2014), which were downloaded
from (http: // global weather data for swat.tamu. edu). The duration of
the study for each of the stations in the study area was divided into
two climatic periods for comparison. The first climatic period
(1979-1997) was for (18) seasons, while the second climatic period
(1998-2014) for (17) seasons.
The study found that the general trend of the drought took a
decreasing trend during the seasons (fall, winter, spring) and (rainy
season) for the period of study (1997-2014) for all the stations of the
study area. The first climatic period (1979-1997) During the seasons
(,fall winter, spring) and (rainy season) for all stations. The wet
seasons for the first season were (71)% (86%) and the dry season was
(29%) (14% ). The second climatic period (1998-2014) led to drought for
all stations in the study area. During the seasons and the vessels of
the rainy season (68%) (78%) The percentage of wet seasons stood at
(32%) (22%).
