The complex interaction of components in the climate system has greatly contributed to uncertainty in climate patterns. Inarguably, anthropogenic factors have relentlessly increased this phenomenon. While innumerable research aimed at forecasting these interactions and their impacts on climate identify three streams of uncertainties as; model responses, external forcing factors and internal atmospheric variability, lack of knowledge on these factors have continue to challenge efficient results pertaining to climate change, its variation and its mitigation. Surface temperature and precipitation on a monthly, seasonal and annual timescale for the period of 1978-2015 obtained from the Turkish Republic of North Cyprus Metrological department. The atmosphere-ocean interaction is herein explored to identify feasible association and impact of a series of teleconnection patterns (AO, NAO, NCP, ENSO, and WeMO) on climate in Northern Cyprus. Pearson and Spearman correlation analysis were employed to establish the possible relationship between precipitation and temperature and teleconnections patterns. NCP proves to be highly dominant in the region, at all timescales but provides the strongest relations with temperature in autumn, winter and spring. NAO and AO show significant negative correlation with temperature in winter and summer whereas ENSO shows the least association in only 21% of the temperature recorded stations; in autumn and summer. WeMO is the sole index which affects rainfall in autumn, winter and summer negatively. Its effect on temperature is seen in summer, autumn and spring both appearing negatively and positively. These results will be relevant in the downscaling of Global Circulation Models.

Assessment of changes in climate indices of the mediterranean climate region of Turkey Çetinkaya , İzem; Yücel, İsmail; Department of Civil Engineering (2020-10-28) As a consequence of climate change, frequency and intensity changes in extreme weather events have occurred. One of the most vulnerable regions of the world that is affected by the climate change is the Mediterranean region. Turkey as a Mediterranean country has a great importance to investigate the changes in climate behavior. 57 stations from Mediterranean climate region of Turkey have been selected as the study area for this thesis. This study aims to assess the climate indices that carry the valua...
Analysis and modeling of spatially and temporally varying meteorological parameter : precipitation over Turkey Aslantaş Bostan, Pınar; Akyürek, Sevda Zuhal; Heuvelink, Gerrad; Department of Geodetic and Geographical Information Technologies (2013) As precipitation is the very important parameter of climate and hydrology, exploring spatial and temporal distribution and variation of this variable can give an idea about climate conditions and water resources in the future. Therefore accurate mapping of the temporal, spatial and space-time distributions of precipitation is important for many applications in hydrology, climatology, agronomy, ecology and other environmental sciences. In this thesis, temporal, spatial and space-time distributions and variat...
Analysis of Relations between Solar Activity, Cosmic Rays and the Earth Climate using Machine Learning Techniques Belen, Bükem; Leloğlu, Uğur Murat; Demirköz, Melahat Bilge; Department of Earth System Science (2021-9-7) The Earth's climate is part of a complicated system that can be affected by many different parameters, both internal and external. Important external forces on the climate are galactic cosmic rays (GCR) and the Sun. Some research has already been conducted to investigate the relationship between the climate and external forces such as the GCR and solar activity. However, the relations are quite complicated and buried into almost chaotic meteorological measurements. This thesis looks deeper into the interact...
Comparison of MODIS-derived land surface temperature with air temperature measurements Georgiou, Andreas; Akcit, Nuhcan (2017-03-23) Air surface temperature is an important parameter for a wide range of applications such as agriculture, hydrology and climate change studies. Air temperature data is usually obtained from measurements made in meteorological stations, providing only limited information about spatial patterns over wide areas. The use of remote sensing data can help overcome this problem, particularly in areas with low station density, having the potential to improve the estimation of air surface temperature at both regional a...
Investigation of Sea Surface Temperature (SST) Anomalies over Cyprus Area Georgiou, Andreas; Akcit, Nuhcan (2016-04-08) The temperature of the sea surface has been identified as an important parameter of the natural environment, governing processes that occur in the upper ocean. This paper focuses on the analysis of the Sea Surface Temperature (SST) anomalies at the greater area of Cyprus. For that, SST data derived from MODerate-resolution Imaging Spectroradiometer (MODIS) instrument on board both Aqua and Terra sun synchronous satellites were used. A four year period was chosen as a first approach to address and describe t...
