According to what is stated in the scientific literature, vegetation cover affects air temperatures in the areas in which it is found and works to reduce them through the processes of evaporation and transpiration, whether from the plant itself or wet surfaces within a specific area. Knowing the exact extent of the effect helps in choosing the most appropriate places to install stations for agricultural monitoring to be truly representative of the agricultural reality, and also helps in knowing the most appropriate safety for planting vegetation within cities. We chose two stations that were installed for agricultural purposes in agricultural areas within the city of Baghdad: Abu Ghraib station (A) in Abu Ghraib district and Al-Rashidiya station (B) in Rashidiya district. The monthly average air temperature for stations A and B was obtained from the Agricultural Meteorological Center of the Ministry of Agriculture for a period of 5 years (2018–2022). The results of this research showed, in general, that station (A) recorded values very close to (B), and in some periods, (B) recorded values higher than (A), and it was not recorded that (A) was higher except in a few months., and statistical analysis of the data shows that the highest difference between them was (1.48) in May 2018, and the lowest difference between them was (0.01). In September 2022, to study the effect of vegetation on temperature, the Natural Difference Vegetation Index (NDVI) was created and NDVI circular maps were made around each station, the first case with a radius of 10/km with an area of (315)/km2 and the second case with a radius of 2/km. With an area of (12.56)/km2. In both areas, no clear effect of vegetation on the temperatures recorded by the two stations was observed, despite the abundance of plants, water bodies, and barren lands surrounding the station. It was found that the most noticeable effect was the vegetation cover closest to the station at a distance ranging from 150 to 200 meters, and this was clearly shown in (A).

Seasonal variability is the complex non-linear response of the physical climate system. There are two types of natural variability: those external and internal to the climate system. In any given season, natural variability may cause the climate to be different than its long-term average. This study examines with the seasonal variation of the maximum temperatures during the summer season. In addition, the maximum temperatures in May become close to the characteristics of the summer season. The monthly data for maximum temperature of May, June and July were used from Iraqi Meteorological Organization and Seismology (IMOS) for 47 years from 1970 to 2017 for Baghdad city. This period was long enough to estimate the range of approaching maximum temperature (Tmax) May to summer. Results revealed a significant Tmax for Baghdad during the second period (1992–2017) and ‎shown similar behavior of Tmax in May to June and July; on the contrary that first period (1970–1991). In second period, two phases have been found out, positive phase and negative phase. The positive phase were happened in 1995, 1999, and 2006, and the negative phase was four cases (1992, 2004, 2013, and 2016), while a few cases recorded in first period. The amplitudes of monthly variability had same distance of leaner correlation especially in 1999 and 2013 that represent coherent wave with summer seasons. The variance difference for Tmax between May and June approximately was 2°C for second study’s period, while exceed this range in first period. This variance change to 7.5°C when found difference between July and May.

Surface Air Temperature (SAT) is an important weather element affecting the climate and its nature, as it greatly affects the nature of the atmosphere prevailing in the city of Baghdad, as well as the main influence on the pressure systems affecting Iraq and thus the city of Baghdad. In this study, the annual SAT for three aspects of temperatures (mean, maximum, and minimum) for Baghdad city of approved 11 years had studied, analyzed and discussed. The sources of data came from two sources. First, Iraqi Meteorological Organization and Seismology (IMOS), which represented the arithmetic average annually of the SAT, maximum and minimum temperature for the period (2009 – 2019). Second source of data was from Mustansiriyah University, atmospheric sciences department of Atmospheric Sciences - college of Science, the data are supported as monthly average for SAT for Baghdad. Results shown Basrah was high annual of SAT than four selective cities in Iraq. The variation of annual SAT was in the end study period where reach to 7 oC in mean of SAT for Basrah city. The trend of SAT for Baghdad city was positive for Mean and maximum, while negative for minimum case. Mustansiriyah station was high than IMOS station by 2 oC for mean of SAT, and 5 oC for maximum SAT.
