Abstract: Wind speed is one of the most meteorological variables which has been changing rapidly with time. Due to the properties of wind speed such as non - stationarity, high fluctuations and irregularity. accurate forecasting becomes a challenge because, The wind speed is easily influenced by many factors, such as latitude, altitude, terrain, pressure, temperature. Therefore, The forecasting of the wind speed is important for many environmental, economic and meteorological applications. Due to the difficulties of the physical models and their non - availability, The Box - Jenkins ARIMA model has been used .Because, it is suitable tool to predict the wind speed and can also be used as an effective tool to get the missing data which existing within the time series of monthly mean wind speed. When Box - Jenkins ARIMA model has used, The ARIMA (15,1,10) model has determined as a suitable model for the monthly mean wind speed for studied stations in Iraqi after passing through the four stages of the model that include Identification of The Time Series, Estimation of The Model Parameters, Diagnostic Check of The Residuals and Model Adequacy and finally, The Forecasting. Many of the evaluation criteria have been used to check the accuracy of the best proposed prediction models by lowest values of each MAE and RMSE and MAPE and the highest values of the correlation coefficient (R2) and correlation coefficient (r), which confirmed the preference of ARIMA(15,1,10) for the monthly mean of wind speed but, This model could not applied on the daily mean of wind speed due to difficult in chose one best - fit model for all time series in all regions of Iraq. Because, The large variance of the wind speed during day and night and has not appeared clear correlation in all stations as shown in monthly data. The best solution is to take the difference of the non - stationarity time series from one lag to the next and then analyze this series after reaching to stationarity. The time series of daily wind speed need to take the difference once for the Baghdad station (d = 1) and twice for the Kirkuk station (d = 2) and three times for the Nasiriya station (d = 3) for reaching to stationarity. When ARIMA(15,1,10) model has been used, All the residuals were found within the confidence intervals and The error rate of using MAPE measure has been found near ( 4% ) for all studied stations in Iraq .

Abstract: onthly and annual values of the total column ozone amount have been analyzed for five locations of Iraq for the period from 1979 to 2012 employing Total ozone Mapping Spectrometer (TOMS) data point and (1o × 1.25o ) grid data, It is found that ozone variation is function of latitude, where the higher values of total ozone column occurs at the northern Iraq which represented by Mosul location, it decreases gradually from northern location (Mosul) passing by middle region locations (Biji, Baghdad and Rutba) to southern location (Basra). The values of Total ozone column start to increase gradually from November to reach its maximum at March then it decreases gradually to reach its minimum values at October. The analysis of the spatial distribution of the monthly average of total ozone column for each month of the year has been made. It is found that the largest of total ozone column amounts occurs systematically over the northern regions during winter whereas in spring and early summer months the maximum values of total ozone column directed to the northwestern regions of the Iraq. Latitudinal gradients in total ozone column are very strong especially during winter, spring and early summer months. The spatiotemporal trend analysis has been made by converting the gridded data from time domain to spatial domain, it is found that the results show that the total ozone column trends was negative during most months of the year, whereas the spatial trend analysis of the second period of study (2005 - 2012) presented positive total ozone column during all months of the year except February and September which presented a negative trends and the overall presented positive trends varied from 0.1 to 2.3 DU / year. Finally the results of the two period trend analysis indicated that the ozonelayer may be responding as expected to the reducing on ozone - depleting substances imposed by the Montreal Protocol.

Abstract: درجة حرارة سطح البحر تلعب دور مهم في التغير المناخي لانها تؤثر على درجة حرارة الهواء مباشرة فوق السطح ومعدل التبخر للماء والذي يؤثر بدوره على درجة حرارة الهواء وتكوين الغيوم والامطار. لذلك دراسة درجة حرارة سطح البحر مهمه في حل المشاكل للظواهر الجوية والبحرية ونظام المناخ للارض. يهدف هذا البحث الى دراسة تاثير تغيرات درجة حرارة سطح البحرالابيض المتوسط(SST) على درجة حرارة الهواء السطحية(T2M) والامطار(TP) لمنطقة الشرق الاوسط خلال الفترة .(1980 - 2009) البيانات المستخدمة في هذه الدراسة تم الحصول عليها من المركز الاوربي وتم عمل ثلاث شبكات للمتغيرات لايجاد العلاقة بين SST وT2MوTP ب استخدام طريقتين للتحليل الاحصائي. ففي الجزء الاول من الدراسة تم استخدام طرق التحليل الاحصائي مثل السلاسل الزمنية ومعامل الارتباط, وتم اختيار ثلاث مواقع (نقاط) على الشبكة في البحر المتوسط واربع مناطق في الشرق الاوسط (بغداد, عمان, دمشق, بيروت).النتائج اظهرت ان التغيرات في درجة حرارة سطح البحر لها اكبر قيمة للميل في شهر تموز (0.06) للنقاط الثلاثة واقل قيمة كانت في الفصول الانتقالية, في شهر نيسان كانت (0.01) للنقطتين الاولى والثالثة, في شهرتشرين الاول كانت قيمة الميل (0.04) في النقطة الثالثة. اما اعلى قيمة للميل لدرجة حرارة الهواء السطحية في الشرق الاوسط فكانت في شهر تموز (0.06) في مدينتي بغداد ودمشق وكانت اقل قيمة في شهر نيسان (0.006 - ) في مدينة عمان. بالنسبة لقيمة الميل للامطار فكانت اعلى قيمة في عمان وبيروت (0.3) خلال شهري كانون الاول وشباط على التوالي, واقل قيمة للميل كانت في بغداد (0.27 - ) خلال شهر كانون الاول. بينت النتائج ان درجة حرارة سطح البحر لها اكبر تاثير على درجة حرارة الهواء السطحية في شهر تموز, بسبب ان معامل الارتباط كانت له اعلى قيمة (0.58), (0.48), (0.50), (0.56) للمدن بغداد وعمان ودمشق وبيروت على التوالي خصوصا مع النقطة الاولى. اقل قيمه خصوصا للنقطتين االثانيه والثالثه فكانت في شهر نيسان, (0.007 - ), (0.08 - ), (0.08 - ), (0.08 - ) للمدن بغداد وعمان ودمشق وبيروت على التوالي.ولوحظ انه لاتوجد علاقة بين درجة حرارة سطح البحر والامطار للمناطق الاربع لان معامل الارتباط له قيم قليله في كل المواسم المطرية.في الجزء الثاي من الدراسة فتم استخدام طريقة التحليل بواسطة الدالة التجربيبة المتعامدة (EOF) للتغاير المكاني واخذت اول نمطين للـEOF الاول والثاني (EOF2, EOF1) وطريقة التحليل بواسطة (PC) للتغاير الزمني للنمط الاول (PC1). استخدمت شبكتين للنقاط للبيانات, الاولى تمثل شبكة SST لمنطقة البحر المتوسط والشبكة الثانية تمثل شبكة ((T2M,TP لمنطقة الشرق الاوسط وبقدره تميز 0.50 x 0.50 وقسمت فترة الدراسة الى فترات تمثل كل عشر سنوات.النتائج بينت ان نسبة التغاير المكاني لدرجة حرارة سطح البحر للـEOF1 ودرجة الحرارة السطحية كانت 97% و95% من التغاير الكلي على التوالي , وهذا يشير الى وجود علاقة محتملة بينهم, بينما التغاير المكاني للامطار سجلت اقل قيمة خلال فترة الدراسة.اما التحليل بواسطه التغاير الزمني بواسطه PC للـ SST فقط لوحظ وجود دوره قوية لها عشر قمم كل عشر سنوات من فترة الدراسة. | Sea surface temperature plays an important role in the climate change, because it affects the temperature of the air immediately above the surface, evaporation rate of water, cloud formation and precipitation. Therefore, the study of sea surface temperature is fairly essential for solving many meteorological and oceanographic problems and climate system of the earth. The aim of this thesis is to study the effect of sea surface temperature (SST) variation of Mediterranean Sea on air surface temperature (T2M) and rainfall (TP) in Middle East during the period (1980 - 2009). The data used in this study obtained from the Europe center (ECMWF) and made three grids of the variables in order to determine the relationship between SST and (T2M, TP) by using two statistical analysis methods. In the first part of study, statistical analysis technique used such as time series and correlation coefficient, and select three location (points I,II,III) on the grid of Mediterranean sea and four locations on Middle East (Baghdad, Amman, Damascus, Beirut). The results show that, The variation of SST has the highest value of trend in July (0.06) for the points I, II, III and the lowest value was in the transition season, in April was (0.01) for point I, III, in October was (0.04) for point III. While the highest value of trend for T2M in Middle East was in July (0.06) in Baghdad and Amman city and the lowest value in April ( - 0.006) in Amman city. For the value of trend of rainfall, the highest value was in Amman and Beirut (0.3) in December and February months respectively, and the lowest value of trend was in Baghdad ( - 0.27) in December month. The results show that the SST has the largest impact on T2M in July, because the correlation coefficients has the highest value (0.58), (0.48), (0.50), and (0.56) for Baghdad, Amman, Damascus and Beirut respectively especially for point I. The lowest value of especially for point II, III, in April was ( - 0.07), ( - 0.008), ( - 0.008) and ( - 0.008) for Baghdad, Amman, Damascus and Beirut respectively. And notes there is no relation between SST and TP for the four locations, because the correlation coefficient has small value in all rainfall months. The second part of the study use the Empirical orthogonal function (EOF) for the spatial variance and take the first two EOF (EOF1, EOF2) mode, and principle component analysis (PCA) tool for the temporal variation of (PC1) mode. Two grids of points have been used for the data; the first one represents the SST grid of Mediterranean Sea area and the second one represents the (T2M, TP) grid of Middle East of 0.50 x 0.50 and the period of study divided into periods every 10 years. The results show that the percentage of spatial variation of EOF1 for SST and T2M was 97% and 95% of total variance respectively, that indicate to have possible relationship between them while the spatial variance of TP record the lowest value in the period of study. The analysis made by the temporal variance of PC for SST show it has strong cycle with 10 peaks every 10 years of the period of study.

Relationships between solar activity (sunspot cycles) with some climate elements such as precipitation, Air temperature was the primary aim of this thesis, biased on many years of observations and using linear correlation coefficients to examine the relations between two variables. The methods of this research were organized in two domains as follows : The first domain : Studied the relation between solar cycles (for about eleven cycles) with (NAO) and with (ENSO). The main results were the long - term variations of NAO are negatively correlated with sunspot activity at the end of the 19th and the beginning of the 20th century, with a correlation coefficient of ( - 0.65), whereas positively correlated for the period (1940 - 2010), with a correlation coefficient of (0.75), links (NAO and ENSO) with air temperature and precipitation have been also studied for three stations, Mosul, Baghdad and Basra. The main results showed that the NAO is closely correlated with air temperature in winter season (higher than summer) for the three stations, but this correlation relatively decreased toward south of Iraq. The relation between NAO and precipitation was oscillated between high and low correlations. The relations between the ENSO with air temperature and with precipitation were not obvious for the three stations. The second domain : is using continuous wavelet transformation by MATLAB technique. The relations between the solar cycles with annual precipitation for the period (1910 - 2000), air temperature, for the period (1871 - 2008) have been studied for Iraq. The results indicated that the sunspot cycles have three main periods, around 11, 21 and 33 year, while the studied climate elements had small periods (3 - 7) as well as the 11, 21, 33 years. After applying moving average according to the periodicities that found by continuous wavelet transformation, relations between solar cycles were closely related to the annual precipitation. Whereas the correlation of solar activity with air temperature was found to vary with place and time

Abstract: The ongoing depleting of oil and gas reserves, combined with the growing concerns about global warming, has made it inevitable to seek alternative resources of energy. To substitute oil produced energy and eventually minimize atmospheric degradation, renewable energy resources have increasingly become attractive and have been widely used. Therefore, this study focuses on one of the most important resources of renewable energy which is wind energy.Wind speed and direction data of Sulaymaniyah Province (airport station) in the north of Iraq in (2012) measured with 10 seconds time interval, were used to calculate wind potential in the site. Wind speed values with 10 seconds time interval are important to calculate wind turbulence intensity. Mean wind speed and standard deviation with (1, 10, and 60 minutes) time intervals were calculated, together with wind speed distribution, wind direction distribution, wind shear, and turbulence intensity; also, the appropriate class of wind turbine was identified.The impact of meteorological parameters (turbulence intensity, and wind shear) on the performance of wind turbine has been calculated using a MATLAB programming language, which was designed and implemented for this study.Results show that the turbulence intensity is the most significant parameter due to its major effects on the useful life time of a wind turbine. In addition, ambient turbulence intensity was determined, and the turbulence generated by wind turbines was calculated, this type of turbulence is called effective turbulence intensity (Ieff). It was found that wind turbine class (C) is a suitable choice to be installed at the study site (Sulaymaniyah airport station).VIAlso, results show that wind shear is a very important concept for wind turbine developers and installers, since a small difference in wind speed can lead to large difference in power output of a wind turbine. This can be achieved either by calculating wind speed at different heights using equivalent wind speed or by calculating wind speed at hub height using power law. It can be concluded that using equivalent wind speed to evaluate the site gives better calculation of mean wind speed available at that site than wind speed calculated at hub height only. In addition, shear exponent calculation as a function of height is more accurate than its assumed constant value (0.14), in power density estimation.Moreover, wind speed data, of Baghdad Province (Al - Mustansiriyah University meteorological station) in the middle of Iraq in (2008) measured with 15 minutes time interval, were used to calculate the characteristic turbulence intensity of small wind turbine, and monthly mean turbulence intensity. It was found that wind turbine class (B) is the best choice in Al - Mustansiriyah University site. In addition, the highest values of monthly mean turbulence intensity at Baghdad (Al - Mustansiriyah University) were obtained during November, and January, while the lowest values were in June, and July.Finally, wind data were analyzed using Weibull distribution function with its parameters (scale and shape), which were calculated using three analytical methods. Results show that the maximum likelihood method (MLM) gives the best calculation for Weibull parameters in both Sulaymaniyah airport and Al - Mustansiriyah University stations.

Abstract: Clouds has a crucial role in the dynamic and thermodynamics of the atmosphere. Precipitation from clouds is of vital importance for human life and activity. Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practiced in airports. The aim of this study is to develop and implement a numerical warm cloud models to simulate microphysical processes within clouds and investigate the effects of seeding process on the formation of raindrops. Results of the modeling the effects of solute on the formation of cloud droplets suggested that the super saturation is decreased by solutes and critical super saturation value depends on the activity of the solute. The results also indicated that Urea is the best solute for decreasing super saturation, as compared with other materials. Bulk modeling of warm clouds showed that updraft, fall speed, radius of cloud element, and surface temperature are the most important factors affecting the microphysical processes within the cloud parcel. An increase in these parameters can lead to an increase in the fallout from cloud. Simple model of warm cloud droplet suggested that updraft, initial drop radius, and liquid water content play an important role in the growth of cloud drop and rain formation. Numerical simulation of warm cloud seeding by salt solution showed that growth of most drops depends on seeding density value, the rate of growth of the cloud drop increase with increasing seeding density in a nonlinear way. The results illustrated that the radius of the large drop plays an important role in growth process while very small radius of small droplets has almost negligible effects on the growth process. It was found that rainfall is increased when seeding density is increased from 0 (the case of no seeding). The results also showed there is an optimum value for seeding density that gives the relatively largest amount of rainfall. Beside seeding density, the updraft radius of the cloud plays an important role in the formation of rain. Therefore the proper seeding density to be used depends on the updraft radius of the cloud

Abstract: Outgoing longwave radiation (OLR) is a thermal energy represents total upward radiation from the Earth - Atmosphere system towards space. Clouds and greenhouses gases trapped and absorb certain wavelengths of OLR and radiated back towards the Earth, this led to adding an amount of heat to the atmosphere. Variation in OLR values would be influenced Earth’s climate system by increasing or decreasing the average temperature of the Earth's surface. The present thesis involves analysis the spatiotemporal distribution of the outgoing longwave radiation (OLR) and developing an OLR estimation models. Dataset acquired from polar orbit satellite Aqua and its instrument the Atmospheric Infrared Sounder (AIRS). The study was carried out using data collected from January 2003 to December 2016 which covered a region [W : 37.5, S : 28.5, E : 49.5, N : 38.5] in a grid of resolution of 1º×1º. The 13 - years data from 2003 to 2015 were used for climatology and for establishing relationships in the developed models, multiple linear regression (MLR) and Artificial Neural Network (ANN)because the suitability of the technique to provide estimates, while the data of the year 2016 was employed to investigate the estimation capacities of these models of monthly - average OLR value in Iraq. The spatiotemporal distribution of monthly averaged values of OLR for 13 years period showed that Winter season have the minimum average values, about (270 15.8) Wm - 2. Start from Spring season OLR levels become increasingly intense and reach (306 16.2) Wm - 2. Summer season became more intense when compared to previous seasons, specifically over the southern parts of Iraq and dominate the highest OLR overall observed average values. These values reached (351 16.2), (360 14.5), (355 12.9) Wm - 2 for June, July and August respectively. As Autumn season start, the reduction of overall average OLR values start. The minimum average values reached in November with a (283.6 12.3) Wm - 2. The results also showed a zonally relationship between OLR and latitude. The spatial variance of OLR values were indicates an indirect zonally relation between OLR and latitude.Different observed meteorological parameters, including (Surface temperature (ST), Relative humidity (RH), and Cloud fraction (CF)) were offered as the input variables for modeling ANN and MLR to get OLR values. For the entire period, these three meteorological parameters were highly correlated (R= 0.980) with measured OLR. Furthermore, satellite data were used in three different locations over Iraq (Mosul, Baghdad and Basrah). Estimations of OLR values were evaluated by using several statistical bases. Comparisons among the three selected cities in test data (the year 2016) showed close agreement between the estimated OLR and measured OLR from AIRS. Mosul city at the north of the study area showed the best statistical performance indicators with the lowest root mean square error (RMSE) of (4.4966 and 1.3853) and highest correlation coefficient (R) of (0.9929 and 0.9993) for the two models (MLR and ANN) respectively, indicating model's efficiency and accuracy. Statistical analysis in term of β (regression constant) showed that surface temperature (1.823 to 2.311) tended to contribute significantly to high OLR values.The estimated results showed a satisfying performance for the ANN model when compared to the MLR model. These results obviously indicate the advantage of using the satellite AIRS data and both of MLR and ANN models to investigate the impact of the atmospheric meteorological parameters on OLR values on cities and country. Finally, the MLR model is used to map the estimated monthly average of OLR over Iraq.
