Large scale moisture flux analysis was carried out for the Mediterranean Basin in order to increase our understanding of the larger scale atmospheric controls on moisture flux convergence that are related to drier and wetter conditions. The seasonal moisture budget (precipitation minus evaporation) was calculated using the National Centers for Environmental Prediction-National Center for Atmospheric Research reanalysis data for the period 1949-2012. Results of the analysis show that the displacements of prevailing atmospheric action centres located over the subtropical mid-east Atlantic (i.e. Azores high) and the north-east Atlantic (i.e. sub-polar or Iceland low) to the north and to south, respectively, generally determine the wet or dry conditions over the Mediterranean Basin. In winter, the eddy fluxes originating from the mid-Atlantic propagate over Europe providing wet conditions in western and central Europe. The contribution of eddies to the moisture budget weaken in summer for the Mediterranean Basin, because of weaker and less frequent frontal activities in general.

Global spatiotemporal consistency between meteorological and soil moisture drought indices Afshar, Mahdı Hesamı ; Bulut, B.; Düzenli, Eren; Amjad, M.; Yılmaz, Mustafa Tuğrul (2022-04-01) In this study, the consistency of a set of meteorological and soil moisture drought indices has been analyzed using the linear relationship between them. Commonly used Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) are compared to soil moisture drought index (SSMI) between the years 1981 and 2019. The most consistent meteorological drought index with SSMI has been selected as the best representative of it for 175,840 pixels, globally. Later, different c...
Calibration and evaluation of wavewatch III under extreme conditions in Eastern Mediterranean and Aegean Sea Basin Bingöl, Cem; Özyurt Tarakcıoğlu, Gülizar; Department of Civil Engineering (2019) In this study, performance of WAVEWATCH III under extreme waves in Eastern Mediterranean Sea and Aegean Sea is assessed using Climate Forecast System Reanalysis wind data. Best source term is selected from all five source terms that is available in WAVEWATCH III for representation of wind waves in the region. Calibration of the selected source term is conducted for Aegean Sea and Turkish Coast of Mediterranean Sea. Three new Turkish State Meteorological Service buoys are utilized in the study which were nev...
Remotely Sensed Terrestrial Water Balance of the Nile Basin Smith, Tiffany; Zaitchik, Ben; Anderson, Martha; Yılmaz, Mustafa Tuğrul; Alo, Clement; Rodell, Matthew (2011-12-05) Satellite-derived estimates of precipitation, evapotranspiration (ET), and water storage have transformed our understanding of hydrological dynamics at the basin scale. At the same time, the profusion of satellite and model-generated hydrological estimates has demonstrated that there is still considerable uncertainty associated with the quantification of hydrologic states and fluxes at basin scale: the use of different combinations of data products can lead to dramatically different conclusions regarding wa...
Intercomparison of rain gauge, radar, and satellite-based precipitation estimates with emphasis on hydrologic forecasting Yılmaz, Koray Kamil; Hsu, KL; Sorooshian, S; Gupta, HV; Wagener, T (American Meteorological Society, 2005-08-01) This study compares mean areal precipitation (MAP) estimates derived from three sources: an operational rain gauge network (MAPG), a radar/gauge multisensor product (MAPX), and the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN) satellite-based system (MAPS) for the time period from March 2000 to November 2003. The study area includes seven operational basins of varying size and location in the southeastern United States. The analysis indicates that agre...
Analysis of teleconnection patterns on climate of Northern Cyprus Nabango, Hope Nabwire; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2019-9) 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...
