| Abstract | ||
| The climate system is very sensitive to the changes caused by the temperature of sea surface, which extremely affecting it ,and to understand this relationship, the coefficient oscillation of the North Atlantic and its association with climate variables, which include all anomalies of surface minimum and maximum temperatures .So, were calculated this study ,used both the National Center (U.S.) for the environment and forecasting (NCEP) to calculate the coefficient of fluctuation of the North Atlantic, and the General Authority form meteorological and seismic monitoring data to calculate the anomaly of minimum and maximum surface temperatures of (January, April, July, October) for the period (1989-2010). The results shows that the climatic changes represented by anomaly surface temperatures and pressure over Baghdad city is associated with the coefficient of fluctuation of the North Atlantic(NAO) coefficient of correlation value equals (0.168 and 0.201), respectively, while the value of the correlation coefficient between the coefficient of fluctuation of the North Atlantic(NAO) and surface pressure anomaly equals (-0.240), so impact of both these climate variables and the coefficient of the North Atlantic oscillation are more in winter than in summer. | ||
