The relationship between storms and extreme ocean waves in the North Sea is assessed using a long-period wave data set and storms identified in the Interim ECMWF Re-Analysis (ERA-Interim). An ensemble sensitivity analysis is used to provide information on the spatial and temporal forcing from mean sea-level pressure and surface wind associated with extreme ocean wave height responses. Extreme o...

-Raptors perform spectacular aerial displays but our understanding of their complexity and functions is still limited. We describe the characteristics of Montagu ́s Harrier (Circus pygargus) sky-dancing displays and evaluate possible sexual functions. Sky-dancing was performed by both sexes, but much more frequently by males. Although occurring throughout the breeding season and into the post-fl...

KUMAR, B.P. and STONE G.W., 2007. Numerical simulation of typhoon wind forcing in the Korean seas using a spectral wave model. Journal of Coastal Research, 23(2), 362–373. West Palm Beach (Florida), ISSN 0749-0208. This study investigates the application of the wave model (WAM) to simulate the generation and propagation of typhoon waves in Korean seas. The model solves the energy balance equati...

The scattering of photons in plasmas is an important diagnostic tool. The region of warm dense matter can be probed by x-ray Thomson scattering. This requires intense x-ray sources, such as the free electron laser (FEL) at DESY Hamburg. We improve the standard treatment of the scattering on free electrons within the random phase approximation (RPA) by including collisions. The dynamic collision...

The intense Compton cooling of ultra-relativistic electrons in the Klein-Nishina regime in radiation dominated environments, such as that found in the Galactic Centre, may result in radically different electron spectra than those produced by Synchrotron cooling. We explore these effects and their impact on the X-ray and γ-ray spectra produced in electron accelerators in this region in compariso...

The southern hemisphere westerly winds have been strengthening and shifting poleward since the 1950s. This wind trend is projected to persist under continued anthropogenic forcing, but the impact of the changing winds on Antarctic coastal heat distribution remains poorly understood. Here we show that a poleward wind shift at the latitudes of the Antarctic Peninsula can produce an intense warmin...

AbstracL Solar flares, coronal mass ejections (CMEs), solar energetic particles (SEPs), and fast solar wind rqrresent the energetic phenomera on the Sun. Flares and CMEs originate from closed magnetic field shuctures on the Sun typically found in active regions and quiescent filamant regions. On the other hand, fast solar wind originates from open field regions on the Sun, identified as coronal...
