Analytical Study of Climate Change Indicators for Minimum Temperatures in Selected Regions of Iraq and their Trends

Abstract

Extreme weather conditions have a severe impact on many important aspects of life, so it is necessary to predict the patterns of these conditions in the future in order to control them. To avoid many disasters that may lead to human lives and cause a lot of damage to the natural environment as well as infrastructure, these indicators are calculated based on daily monitoring of minimum temperatures.In this study, we have selected three indicators of extreme climatic phenomena for minimum temperatures, represented by those indicators identified by the Expert Group on Climate Change Monitoring. These indicators reveal the existence of climate change or not. The work of this joint team between the Climate Science Committee, the World Climate Research Program, and the Joint Technical Committee on Oceanography and Marine Meteorology, all of which met under the auspices of the World Organization. Climate indicators calculated from daily temperature data are also one of the ways to describe the frequency and intensity of extreme climatic phenomena. This study was carried out through R clim Dex, an open-source program based on the definitions developed by the World Meteorological Organization's Panel of Experts on Climate Change, which was issued in 2009, as in Table (1), and the analysis of trends in extreme microtemperature chains on various human activities.
