Since teleconnections are significant components of the natural climatic variability, any future climatic changes are expected to influence their structure and intensity and subsequently their implications on the regional climate. Taking into account these findings, the aim of this study is to investigate the existence of EMP and its potential spatial variations in the future, in connection with the IPCC Emission Scenarios of greenhouse gases. For this purpose, gridded daily data of geopotential height at 500 hPa have been used. For the present climate, the datasets derive from NCEP/NCAR archive and cover the period 1958 to 2003 on 2.5°x 2.5° latitude by longitude grid. For the future, the datasets derive from HadAM3P model for the period 2070-2100, on the basis of two different IPCC scenarios. Two different approaches were employed on a seasonal basis in order to identify the centres of action for this pattern: Rotated Principal Component Analysis and Correlation analysis. First, the validation of the model results (control run) against the gridded data of NCEP/NCAR for the present period 1960-1990 demonstrated that the two datasets agree quite well. Then, it was found that the EMP exists in the future (2070-2100) under different scenarios of greenhouse gases emissions and subsequent global warming but not in its present form. For the scenario that predicts global temperature increase by 2.3°C, the pattern forms with a northeastward shift of the two poles relative to location in the present climate. If the global temperature increase is higher (of 3.3°C), the whole EMP is shifted to the southeast by almost 10°, as compared to its present form. These results are collaborated by both approaches employed.</p></abstract><publication_date><month>04</month><day>29</day><year>2013</year></publication_date><pages><first_page>195</first_page><last_page>203</last_page></pages><publisher_item><identifier id_type="pii">410</identifier></publisher_item><doi_data><doi>10.30955/gnj.000410</doi><timestamp>1714154115</timestamp><resource>https://journal.gnest.org/publication/410</resource></doi_data></journal_article></journal></body></doi_batch> </div>
