Tropical cyclones occur in the tropical areas in general. Mediterranean hurricanes are cyclones with tropical characteristics and known as medicanes which occasionally develop in the Mediterranean Sea. The long waves in tropical cyclones are generated by atmospheric pressure disturbance and surface wind fields. Pressure and wind data are available in international data sources CFSR and ECMWF ERA5. This study is carried out to simulate tropical cyclones using the numerical modelling NAMI DANCE and compare the results of computed water levels with the observations and measurements. The correlation between CFSR and ECMWF ERA5 data of atmospheric pressure and wind fields is also investigated for comparison. As the case studies firstly, the numerical modelling is applied to the tropical cyclone event Dorian from 28 August to 10 September 2019 and the results are compared with the observations and measurements. Secondly, Mediterranean storms Medicane Trudy from 11 November to 14 November 2019 and Medicane Zorbas from 28 August to 30 September 2018 are simulated. The results of computed ocean waves are compared with the measurements from tide gauge stations. The results are presented with comparisons and discussions.

Evaluating the use of radar precipitation data in simulating a flood event in Terme Samsun Turkey Akyürek, Sevda Zuhal (2016-10-10) Floods caused by convective storms in mountainous regions are sensitive to the temporal and spatial variability of precipitation. In developing countries, researches and authorities working on this issue have to deal with lack of data. Even a dense raingauge network may not be able to state variability of the precipitation patterns especially in mountainous regions. Space-time estimates of rainfall from weather radar can be a remedy to represent pattern of the rainfall with some inaccuracy. In the field of ...
Evaluating the use of different precipitation datsets in flood modelling Akyürek, Sevda Zuhal (2016-04-17) Satellite based precipitation products, numerical weather prediction model precipitation forecasts and weather radar precipitation estimates can be a remedy for gauge sparse regions especially in flood forecasting studies. However, there is a strong need for evaluation of the performance and limitations of these estimates in hydrology. This study compares the Hydro-Estimator precipitation product, Weather Research and Forecasting (WRF) model precipitation and weather radar values with gauge data in Samsun-T...
Assessment of flash flood events using remote sensing and atmospheric model-derived precipitation in a hydrological model Yücel, İsmail (2011-07-07) Remotely-sensed precipitation estimates and regional atmospheric model precipitation forecasts provide rainfall data at high spatial and temporal resolutions with a large-scale coverage, and can therefore be potentially used for hydrological applications for making flash flood forecasts and warnings. This study investigates the performance of the rainfall products obtained from the Hydro Estimator (HE) algorithm of NOAA/NESDIS and the Weather Research and Forecasting (WRF) model, and their use in a hydrolog...
Analysis of drought events in North Cyprus Khan, Sana; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2019-9) Drought is a temporary climatic condition which arises due to lack of precipitation. It has become an important natural phenomenon for North Cyprus due to its semi-arid climate and with vulnerabilities culminating as a result of climate change there is a dire need to keep a good track of such extreme climate events for sustainable water resource management. The island is facing serious water shortages, and for Mediterranean region climate change impacts on water resources has become a pressing issue, hence,...
Analysis of the 2007 and 2013 Droughts in Turkey by NOAH Hydrological Model Bulut, Burak; Yılmaz, Mustafa Tuğrul (2016-10-01) Analysis of drought, which is classified as a natural disaster, is globally considering the damage it gives. As a result detection of its characteristics is essential for understanding and reducing the effects of this natural disaster and for imminent prediction. In this study, soil moisture estimates obtained from NOAH hydrological model and normalized difference vegetation index obtained from MODIS observations are used to analysis the recent droughts in Turkey. With the utilization of these parameters th...
