| Abstract | ||
| Depending on metrological information measured for Baghdad station, which represented the arithmetic average( monthly) of the temperatures and the maximum temperatures for the period 2000-2010,And we have obtained from the Iraqi Meteorological Organization and Seismology(IMOS),The anomalies monthly values of these two variables account in an attempt to understand the relationship between them and the effect of one over the other and using Sigma plot program shows that: the months that represents the beginning of seasons separated for Baghdad station (December-June-September-March) Variation between Tmean and Tmax in the first five years is happening 2000-2004)) in other words, the effect of the Tmax be More on theTmean and thus have a positive variance and again Tmean be the biggest impact on the Tmax and then followed by a period similar to or match the behavior of (2005-2009), in 2010 starts anothervariance , while the half season (January -April-October to July) which occure to match similar in behavior and convergence of values where this period represents the stability of the temperature for each season and that the highest fluctuation of maximum temperatures was 2.9 in 2008 and the highest anomaly monthly average was in 2006 and amounted to 2.9 also, This was the first part of the search, while the second part is calculating Temperature-Humidity Index( THI)or discomfort index using the monthly average temperatures and again using the maximum temperature show that in Winter difference between the THI values when using Temp Average (8-14) either using Temp max be (13-19) Thus, the THI average be within the extremely cold climates and uncomfortable, but they are perfect in maximum temperature , while the summer is THI values when use Temp Average (24.9-27.7) and when using Temp max be (29.9-34) and thus, there is a difference of 5-7 degrees between the two cases, and both cases are under extreme heat and thus they are not suitable for the comfortable o f humanThus, the monthly average temperature does not give a clear picture of the actual behavior of the temperature without taking into consideration the impact of the maximum and minimum as influential real temperature Weather . | ||
