This paper aims to describe a deterministic generation of extreme waves in a typical towing tank. Such a generation involves an input signal to be provided at the wave maker in such a way that at a certain position in the wave tank, say at a position of a tested object, a large amplitude wave emerges. For the purpose, we consider a model called a spatial-NLS describing the spatial propagation o...

The session on “Extreme and Rogue Waves” has been proposed and successfully run for ten years by the Natural Hazard Division of the European Geosciences Union, previously known as the European Geophysical Society. Proceedings of the session were published by Pelinovsky and Kharif (2006, 2008), Kharif et al. (2006) and Pelinovsky et al. (2009). Progresses in this field are further documented by ...

Extreme cold and heat waves, characterized by a number of cold or hot days in succession, place a strain on people's cardiovascular and respiratory systems. The increase in deaths due to these waves may be greater than that predicted by extreme temperatures alone. We examined cold and heat waves in 99 US cities for 14 years (1987-2000) and investigated how the risk of death depended on the temp...

The significant effect of waves on coastal and marine activities urges the precise identification of wave characteristics using field measurements, theoretical studies, physical modeling or numerical simulations. In order to study thoroughly the wave climate in the Caspian Sea, a wave modeling and hindcast project was performed by Iranian National Center for Oceanography. In this study, one of ...

[1] This study investigates the magnitude and spatial extent of extreme summer temperature and specific humidity events in the extratropical northern hemisphere (NHEXT) using the NCEP Reanalysis (1979–2012) and the 20 century reanalysis (1871–2010). Specifically, we look at the percentage of area exceeding standard deviation thresholds in layer-averaged (500mb–1000mb) temperature and surface-le...

The mathematical tools of large deviation theory for rare events are illustrated with some simple examples. These include discrete and continuous Gaussian processes, importance sampling, and evolution equations of the Langevin type. Some of these methods have been used in the study of rogue surface waves but it seems that large deviation theory could have much wider application in geophysical p...

The global climate has changed significantly, characterized by the warming of the surface air temperature, which seriously affects public health. We examined the trends of extreme temperatures, heat waves and cold spells in a subtropical city of Guangzhou, China, during 1951–2015. Specifically, the relationship between ENSO (El Niño–Southern Oscillation) events and heat waves/cold spells was di...
