Effects of a wind-driven cross-shelf large river plume on biological production and CO2 uptake on the Gulf of Mexico during spring
biological production Mexico during spring
2014/4/2
The plume of Mississippi and Atchafalaya River system (MARS) is normally confined to the continental shelf
and extends westward. During March 2010, while weather in North America was dominated by unu...
Gone with the Wind ON_Mars (GOWON): A Wind-Driven Networked System of Mobile Sensors on Mars
Gone the Wind ON_Mars GOWON Wind-Driven Networked System Mobile Sensors Mars
2012/2/24
We propose a revolutionary way of studying the surface of Mars using a wind-driven network of mobile sensors- Gone with the Wind ON_Mars (GOWON). GOWON is a scalable architecture that will allow in-si...
Analysis of Wind Load Effect on the Roof of Low-Rise Building in the Mountain Terrain
Characteristics of Wind Field Computation Fluid Dynamics (CFD) Low-Rise Buildings Mountain Terrain Wind Load on Roof
2011/12/20
The wind conditions of the low-rise building in the mountain terrain are different because they have the characteristics of different landforms. When the typhoon comes, the possibility of structural d...
Stereo Monitoring and Analysis on Wind Energy Source in Chongqing
Complemental Meteorology Station Observing Wind Data Professional Observing Tower Stereo Monitoring Wind Energy Resource
2011/12/21
In this paper, sequential 12 months’ wind data was used which is obtained from professional observing towers and meteorological stations in Chongqing. Wind energy source was calculated and analyzed. T...
We observed the young pulsar J1357--6429 with the {\it Chandra} and {\it XMM-Newton} observatories. The pulsar spectrum fits well a combination of absorbed power-law model ($\Gamma=1.7\pm0.6$) and bla...
Enriched haloes at redshift $z=2$ with no star-formation: Implications for accretion and wind scenarios
galaxies:evolution galaxies:formation galaxies:high-redshifts galaxies
2011/10/13
In order to understand which process (e.g. galactic winds, cold accretion) is responsible for the cool (T~10^4 K) halo gas around galaxies, we embarked on a program to study the star-formation propert...
Post-Periastron Gamma Ray Flare from PSR~B1259-63/LS 2883 as a Result of Comptonization of the Cold Pulsar Wind
Comptonization Cold Pulsar Wind
2011/10/19
The recent detection of gamma rays with the {\it Fermi} Large Area Telescope (LAT) from the binary system PSR B1259-63/LS2883 provides unique information about the pulsar wind. Although the nature of ...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
Dust driven mass loss from carbon stars as function of stellar parameters - II. Effects of grain size on wind properties
AGB and post-AGB – Stars: atmospheres – Stars: carbon – Stars: circumstellar matter – Stars: evolution – Stars: mass loss –2 Hydrodynamics – Radiative transfer
2011/9/30
In this paper we explore grain size effects on wind properties of carbon stars, using a generalized description of radiative cross sections valid for particles of arbitrary sizes. The purpose of the s...

2011/10/13
The Balmer H alpha emission line in the stationary spectrum of SS 433 has a component originating in the wind above the accretion disk. The Doppler motion of this line is a blurred representation of t...
Rossby waves and polar spots in rapidly rotating stars: Implications for stellar wind evolution
magnetic fi eld – Stars: activity – Stars: starspots – Stars: oscillations – Physical data and processes: Magnetohydrodynamics
2011/10/10
Rapidly rotating stars show short-period oscillations in magnetic activity and polar appearance of starspots. The aim of this paper is to study large-scale shallow water waves in the tachoclines of ra...

Abstract: The periodic wind-tree model is a family T(a,b) of billiards in the plane in which identical rectangular scatterers of size axb are disposed at each integer point. It was proven by P. Hubert...
Changes in Sea-Level Pressure over South Korea Associated with High-Speed Solar Wind Events
solar-terrestrial weather sea-level pressure solar wind
2011/9/30
We explore a possibility that the daily sea-level pressure (SLP) over South Korea responds to the high-speed solar wind event. This is of interest in two aspects: First, if there is a statistical asso...
