Abstract:
The study aims to identify the liturgical properties in the city of Nassiryah, especially, in terms of temperature , wind speed and their direction. Also it aims to discover the presence of thermal island and study the effect of factor on this city .Moreover, it aimes to indicate of the heat island on the climate of the city. The problem of the study is to show if there is heat island in the city of nassiryah and generated by minor problems. Also it aims to indicate the effect of spatial disparities of urban land uses in the formation of the heat island phenomenon and the heat island effect in the climate elements in the city of nassiryah.The researcher of this study on the field work. The work began by dividing of the city into seven axes to cover all of the city. Each of these axes contained number of monitoring points. , degree of, a ,humidity ,downwind to find out a thermic island .It also studies the affected on the city and the heat island on the climate of the city .The study depends upon fieldwork it has been divided into seven axes .Each axe involves a number of monitoring points. And that number depends on the length of each axis by 75 monitoring points : representing(Haboubi square) center of the city is the starting point for a team of field who has been trained on how to measure, and has field monitoring operations by digital measure devices for measuring temperature, wind speed and direction, relative humidity for all seasons of the year as such month (October) autumn month (January) winter month (April),the spring observations field, it shows the existence of a major heat island shows in addition to the secondary Islands.It was the highest thermal difference between the rural city center next to it through observation amounting to (8(16;00) in the axis (Habubi the bo Fayyad),the higher the difference in the relative humidity was (15%) in the axis (Habubi thermal power plant Nassiryah) in field of winter balances first seveno,clock in the evening (13/ January/2016), either wind speed recorder the biggest difference in the axis ( Habubi neighborhood redemption) reached (6.8m/s)in the first Winter balances five o'clock in the morning (13/January/2016) the station readings in the city of Nassiryah reached a high thermal difference between them and the center was(4.7m) balances autumnal third at seven in the evening, the higher the difference in the relative humidity was (12.7%) in the winter balances theIIsecond time the second afternoon the highest difference in wind speed reached (8.5m/s) in the winter balances the second time in the afternoon, and in the balances morning winter. The study highlighted the statistical relationships that have been followed and reliable in the study, for example .the factor of simple correlation simple regression that illustrates the statistical relations weather trdah or the reverse in terms of impact between the natural and human geographical factors.The results of statistical analysis have shown that there is a strong extreme correlation between a dimension factor for bodies of water with the temperature which is (0.997) and poorly inversely correlation is between the temperature and distance from the center because of the high population density and the results show that the correlation factor is a strong proportional correlation between the distance from the center and the speed of wind which is (0.849).The results indicate that there is a strong correlation between the temperature and the relative humidity value of the correlation coefficient( - 0.986).Also there is a weak reversal link between a population density and the temperature 5m.The value of Pearson, a correlation coefficient, is ( - 0.032).The results of statistical analysis show that there is the presence of extrusive link an average (0.712) between the temperature and the density of traffic. The results also show that there is a strong factor of the link is (0.993).There is also a strong reversal proportional correlation between the temperature and the percentage of vegetation in the city as it is ( - 0.904).the results indicate there is a strong proportional correlation between the it is ( - 0.904).the results indicate there is a strong proportional correlation between the relative humidity and the vegetation in the city which is (0.839).Also the results show that there is a strong extrusive link with the temperature which is (0.888).
