An explainable two-stage machine learning approach for precipitation forecast
Senocak, Ali Ulvi Galip; Yılmaz, Mustafa Tuğrul; Kalkan, Sinan; Yücel, İsmail; Amjad, Muhammad (2023-12-01)
A common post-processing approach to improve precipitation forecasts is to use machine learning models such as artificial neural networks (more specifically, multi-layer perceptrons) as black-box systems. These models util...
Assessment of changes in return levels of historical and projected high and low flows of upper Euphrates basin in Turkey using nonstationary models
Aziz, Rizwan; Yücel, İsmail (2023-04-15)
Owning to climate changes and other anthropogenic interventions, the frequency and return levels of extreme flows cannot be treated as stationary. This study quantifies the changes in return levels by fitting the stationar...
Impacts of Climate Change on Extreme Climate Indices in Türkiye Driven by High-Resolution Downscaled CMIP6 Climate Models
Gumus, Berkin; Oruc, Sertac; Yücel, İsmail; Yılmaz, Mustafa Tuğrul (2023-04-01)
CMIP6 Earth System Models Project Greater Acceleration of Climate Zone Change Due To Stronger Warming Rates
Bayar, Ali Serkan; Yılmaz, Mustafa Tuğrul; Yücel, İsmail; Dirmeyer, Paul (2023-04-01)
Warming climate and precipitation changes induce notable shifts in climate zones. In this study, the latest generation of global climate models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) and the previou...
Spatiotemporal trends in daily and subdaily rainfall extremes and return levels in Turkey
Albayrak, Derya; Şen, Ömer Lütfi; Yücel, İsmail (2022-11-01)
In this study, we present the long-term daily and subdaily station data of annual extreme rainfall (1970-2015) and the trend analyses in rainfall regimes in Turkey. Trends in 5, 10, 15, and 30 min, 1, 2, 6, 12, and 24 hr o...
Sensitivity of WRF-derived hydrometeorological extremes to sea surface temperatures in regions with complex topography and diverse climate
Pilatin, Heves; Yücel, İsmail; Düzenli, Eren; Yılmaz, Mustafa Tuğrul (2021-12-15)
© 2021 Elsevier B.V.This study investigates the impact of sea surface temperature (SST) describing the lower boundary of Weather Research and Forecasting (WRF) model on the extreme weather events that occurred on the Medit...
Improving WRF-Hydro runoff simulations of heavy floods through the sea surface temperature fields with higher spatio-temporal resolution
Kilicarslan, Berina Mina; Yücel, İsmail; Pilatin, Heves; Düzenli, Eren; Yılmaz, Mustafa Tuğrul (2021-09-01)
This study investigates the impact of the spatio-temporal accuracy of four different sea surface temperature (SST) datasets on the accuracy of the Weather Research and Forecasting (WRF)-Hydro system to simulate hydrologica...
Intercomparison of the expected change in the temperature and the precipitation retrieved from CMIP6 and CMIP5 climate projections: A Mediterranean hot spot case, Turkey
Bağçacı, Soner Çağatay; Yücel, İsmail; Düzenli, Eren; Yılmaz, Mustafa Tuğrul (2021-07-01)
The performances of a large number of Global Circulation Models (GCMs) belonging to the latest release the Coupled Model Intercomparison Project phase 6 (CMIP6) in comparison with its predecessor CMIP5 are evaluated for mo...
Evaluating the performance of a WRF initial and physics ensemble over Eastern Black Sea and Mediterranean regions in Turkey
Düzenli, Eren; Yücel, İsmail; Yılmaz, Mustafa Tuğrul (Elsevier BV, 2021-01-15)
The physics- and initial-based ensemble approach for Weather Research and Forecasting (WRF) model is applied for predicting four different extreme precipitation events that occurred in summer and autumn over the two most f...
Assessing nonstationarity impacts for historical and projected extreme precipitation in Turkey
Aziz, Rizwan; Yücel, İsmail (Springer Science and Business Media LLC, 2021-01-01)
The temporal variability in yearly and seasonal extreme precipitation across Turkey is investigated using stationary and nonstationary frequency approach. Four frequency distributions namely, generalized extreme value (GEV...
