Determining the seasonal drought north of the latitude of 34 degrees in Iraq for the period (1991-2022(
Abstract
This research aims to identify the dry and wet seasons north of latitude (34) degrees in Iraq using the Standardized Precipitation Index (SPI) based on climatic readings from ten climatic stations, as well as supplemental stations for spatial completion, for the period (1991-2022). Rainfall data was downloaded from the website:https://power.larc.nasa.gov/data The research found that the Duhok station retained the highest rate for wet seasons, while the Haditha station retained the highest rate for dry seasons. The study period was divided into two climatic periods for comparison, and the results of the first climatic period (1991-2008) showed that dry seasons were the most frequent in most stations in the study area. As for the second climatic period (2009-2022), wet seasons tended to increase in most stations in the study area, with the moderate drought and moderate moisture categories being the most frequent during the study period.
