The Role of Teleconnection Patterns on Wind Speed of Iraqi-Kurdistan Region

Abstract

Changes in the wind speed of the Iraqi-Kurdistan region are associated with many types of teleconnection patterns. Daily wind speed datasets for eight meteorological stations in the Iraqi-Kurdistan region were gathered from Sulaymaniya, Penjwen, Hallabja, Kalar, Erbil, Sallahadin, Zakho, and Duhok weather stations. spectral comparability between the daily wind speed of the eight sites and prominent atmospheric indices was implemented for the North Atlantic Oscillation (NAO), Southern Oscillation (SO), Mediterranean Oscillation (MO), and Arctic Oscillation (AO), using the multi-taper method (MTM) for spectral analysis to find the source of the wind speed cycle of the cites for the study area. It was found that the common cycles for the eight stations are 2.22, 2.5, 3.33, 3.7, 4.35, 5.56, 7.14, 10, and 14.29 cycles. It is obvious that there are common cycles between each of the NAO, SO, MO, and AO indices and the cycles of daily wind speed of the eight stations. The results of this study will allow us to understand the relation between the regional daily wind speeds patterns fluctuations and the global teleconnection patterns and also to forecast the behavior of daily regional wind speed.
