An observation-constrained multi-physics WRF ensemble for simulating European mega heat waves
multi-physics WRF ensemble simulating European mega heat waves
2015/8/6
Many climate models have difficulties in properly reproducing climate extremes, such as heat wave conditions. Here we use the Weather Research and Forecasting (WRF) regional climate model with a large...
The Contribution of Waves in Mixing Processes of the Patos Lagoon Plume
Vertical Mixing Tridimensional Numerical Modeling Stratification
2013/3/11
The analysis of wave effects above salinity is important in order to define mixing processes and their potential to change density gradients, since action in the region of the Patos Lagoon plume is hi...
Attenuation of P, S and Coda Waves in the NW-Himalayas, India
Attenuation Quality Factor Frequency Dependence NW Himalayas
2013/3/7
The frequency-dependent characteristics of P- and S-wave attenuation in the upper crust of NW Himalayas have been estimated using local earthquakes for a frequency range of 1.5 to 18 Hz. A total of 43...
Mechanism of Elastic Waves Reflection in Geological Media
Elastic Waves Phonons Heterogeneous Media
2013/3/7
Reflecting properties of layered geological media are substantiated in the framework of phonon-phonon mechanism of elastic wave propagation in porous media. In this scope the reflection coefficient is...
New York's Blueprint for Climate Resilience--Panel Tells City to Brace for Heat Waves, High Water（图）
New York's Blueprint Climate Resilience Panel Tells City Heat Waves, High Water
2009/12/21
As world leaders gather at the Copenhagen climate summit, New York City is working on ways to respond to expected heat waves and sea-level rise. A strategy devised by 15 experts, including eight from ...
Further study on the role of atmospheric gravity waves on the seismo-ionospheric perturbations as detected by subionospheric VLF/LF propagation
Further study atmospheric gravity waves seismo-ionospheric perturbations VLF/LF propagation
2009/12/8
As the target earthquake we have taken a huge earthquake (EQ) named Miyagi-oki earthquake on 16 August 2005 (with magnitude of 7.2) and we have analyzed the 4 month period including the date of this E...
Turbulent wind waves on a water current
Turbulent wind waves water current gravitation force
2010/1/28
An analytical model of water waves generated by the wind over the water surface is presented. A simple modeling method of wind waves is described based on waves lengths diagram, azimuthal hodograph of...
Relationships of surface air temperature anomalies over Europe to persistence of atmospheric circulation patterns conducive to heat waves
surface air temperature Europe persistence atmospheric circulation patterns
2010/1/27
Heat waves are among natural hazards with the most severe consequences for human society, including pronounced mortality impacts in mid-latitudes. Recent studies have hypothesized that the enhanced pe...
Observation evidences of atmospheric Gravity Waves induced by seismic activity from analysis of subionospheric LF signal spectra
Observation evidences atmospheric Gravity Waves seismic activity LF signal spectra
2009/12/30
We analyze variations of the LF subionospheric signal amplitude and phase from JJY transmitter in Japan (F=40 kHz) received in Petropavlovsk-Kamchatsky station during seismically quiet and active peri...
Meteotsunamis:atmospherically induced destructive ocean waves in the tsunami frequency band
Meteotsunamis destructive ocean waves tsunami frequency band
2009/12/30
In light of the recent enhanced activity in the study of tsunami waves and their source mechanisms, we consider tsunami-like waves that are induced by atmospheric processes rather than by seismic sour...
Freak waves in 2005
Freak waves 2005
2009/12/30
Information about freak wave events in the ocean reported by mass media and derived from personal observations in 2005 is collected and analysed. Nine cases are selected as true freak wave events from...
Were freak waves involved in the sinking of the Tanker "Prestige"?
Were freak waves sinking Tanker "Prestige"
2009/12/30
This paper deals with the possible involvement of freak, rogue or giant waves in the damage suffered by the Tanker Prestige, which eventually led to its sinking. By reason of their very characteristic...
