One of the interesting marine events is the long wave generation due to spatial and temporal changes of atmospheric pressure and wind fields during storm events. These kind of phenomena is called as storm surge and cause basin wide and local water level changes in sea surface and sometimes amplifies at some regions. There are examples of these kinds of event in all over the world. In this study the atmospheric pressure and wind fields are used as the input to the numerical model NAMI DANCE which solves Nonlinear Shallow Water Equations. The new modified version of the numerical model is tested using regular shaped pressure and wind fields in regular shaped flat basins. It is applied to case studies in Caribbean region for Irma and Maria Hurricanes and the results are compared with the observations. The model is also applied to recently happened January 18, 2018 Aegean Sea Storm Event and September 29-30 18, 2018 Medicane Event.

Long waves generation and coastal amplification due to atmospheric pressure disturbances Metin, Ayşe Duha; Yalçıner, Ahmet Cevdet; Özyurt Tarakcıoğlu, Gülizar; Department of Civil Engineering (2016) The cause of the occurrence of ebb or abnormal waves which are occasionally observed on the coasts is related to the spatial and temporal changes of atmospheric pressure. Because, low atmospheric pressure leads to static water level rise in a part of the marine area and high atmospheric pressure leads to static water level drop in another zone, water level throughout the entire marine area is deformed. This deformation moves as wave, sometimes amplifies on the shore. Due to the changes of atmospheric pressu...
Multiregional Satellite Precipitation Products Evaluation over Complex Terrain Derin, Yagmur; Anagnostou, Emmanouil; Berne, Alexis; BORGA, Marco; BOUDEVILLAIN, Brice; BUYTAERT, Wouter; CHANG, Che-Hao; DELRIEU, Guy; HONG, Yang; HSU, Yung Chia; LAVADO-CASIMIRO, Waldo; MANZ, Bastian; MOGES, Semu; NIKOLOPOULOS, Efthymios I.; SAHLU, Dejene; SALERNO, Franco; RODRIGUEZ-SANCHEZ, Juan-Pablo; VERGARA, Humberto J.; Yılmaz, Koray Kamil (American Meteorological Society, 2016-06-01) An extensive evaluation of nine global-scale high-resolution satellite-based rainfall (SBR) products is performed using aminimumof 6 years (within the period of 2000-13) of reference rainfall data derived from rain gauge networks in nine mountainous regions across the globe. The SBR products are compared to a recently released global reanalysis dataset from the European Centre for Medium-Range Weather Forecasts (ECMWF). The study areas include the eastern Italian Alps, the Swiss Alps, the western Black Sea ...
Long wave generation and coastal amplification due to propagating atmospheric pressure disturbances Dogan, Gozde Guney; Pelinovsky, Efim; Zaytsev, Andrey; Metin, Ayse Duha; Özyurt Tarakcıoğlu, Gülizar; Yalçıner, Ahmet Cevdet; Yalçıner, Bora; Didenkulova, Ira (2021-02-01) Meteotsunamis are long waves generated by displacement of a water body due to atmospheric pressure disturbances that have similar spatial and temporal characteristics to landslide tsunamis. NAMI DANCE that solves the nonlinear shallow water equations is a widely used numerical model to simulate tsunami waves generated by seismic origin. Several validation studies showed that it is highly capable of representing the generation, propagation and nearshore amplification processes of tsunami waves, including inu...
Numerical Modeling of Long Waves from Atypical Sources: Atmospheric Disturbances and Volcanic Origin Doğan Bingöl, Gözde Güney; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2022-6-30) Earthquakes are the main cause mechanisms of tsunamis and large tsunamigenic earthquakes, especially in the subduction zones, occur on relatively much shorter timescales, but destructive tsunamis are also produced by volcanic eruptions, which have been threatening the coastal communities throughout history. Furthermore, while earthquake-generated tsunamis have been studied immensely, there is less focus on research related to tsunamis induced by atmospheric disturbances (meteotsunamis). Consequently, this s...
Tsunami focusing and leading wave height Kanoğlu, Utku (null; 2016-04-17) Field observations from tsunami events show that sometimes the maximum tsunami amplitude might not occur for the first wave, such as the maximum wave from the 2011 Japan tsunami reaching to Papeete, Tahiti as a fourth wave 72 min later after the first wave. This might mislead local authorities and give a wrong sense of security to the public. Recently, Okal and Synolakis (2016, Geophys. J. Int. 204, 719-735) discussed "the factors contributing to the sequencing of tsunami waves in the far field." They consi...
