Dynamical Fluctuation of Troposphere Height Over Baghdad City

Troposphere height has a wide interaction with other atmospheric components, it gives a good indication about what happened inside, therefore this work tried to investigate the heat rate effect on troposphere height especially after the global warming intensity and increase temperature degree rate along the time, thus the study covered 13 years to understand the real behavior of troposphere. Data of this work given from the European center for medium-range weather forecasting (ECMWF) over Baghdad city, the result showed that there is a fluctuation with troposphere height and the difference between a higher and lower point in winter was about (120 m) and that was higher than its rate on summer which was about only (30 m), also the result denoted that the fluctuation frequency becomes lower in the late of the study period. On the other side, the study reached to that the coherence between the temperature fluctuation and troposphere height fluctuation become higher in summer as compared with winter but in general the troposphere height recorded increasing trend over time of the study period.
