Exploring wind direction and SO2 concentration by circular-linear density estimation
Circular distributions Circular kernel estimation Circular{linear data Copula.
2012/9/17
The study of environmental problems usually requires the description of variables with di er-ent nature and the assessment of relations between them. In this work, an algorithm for exible estimation o...
Combined Effect of Hill Arrangement, Wind Direction and Wind Speed on Bending Angles of Culms and Lodging Levels in Rice Plant
Bending angle Lodging level Major axis of a rice hill Rice hill Wind direction Wind speed
2009/8/6
This experiment started from the observation that the cross section of a rice hill was ellipse in shape. When two rice plants cv. Koshihikari were transplanted in a 1/2000 are Wagner pot, the rice hil...
Improvement of Ocean Wind Speed Retrieval Accuracy Taking Into Account a Relative Wind Direction on Observed Brightness Temperature with Microwave Radiometer
relative wind direction ocean wind speed microwave radiometer
2009/3/20
An ocean wind retrival method with microwave radiometer data is proposed taking into accout relative wind directions on observed brightness temperature. The proposed method is based on the geophysical...
The Response of Surface Gravity Waves to Changing Wind Direction
Surface Gravity Waves Changing Wind Direction
2009/2/9
The behavior of a wind-sea is investigated for wave directions differing from the local wind direction. To describe the phenomenon we added the mean wave direction as an additional prognostic quantity...
Wind Direction and Equilibrium Mixed Layer Depth in the Tropical Pacific Ocean
Wind Direction Equilibrium Mixed Layer Depth Tropical Pacific Ocean
2009/1/16
The normal equilibrium state of the tropical Pacific mixed layer is explained by the steady state solution for the maximum vertical penetration of oceanic turbulence generated by local atmospheric for...
Wind Direction and Equilibrium Mixed Layer Depth：General Theory
Wind Direction Equilibrium Mixed Layer Depth General Theory
2009/1/16
A usually neglected Coriolis term in the turbulent kinetic energy budget of the ocean surface mixed layer is examined for the special case of a steady-state mixed layer depth with no entrainment. In t...
Correlation between traffic density and particle size distribution in a street canyon and the dependence on wind direction
traffic density particle size distribution street canyon wind direction
2009/1/15
Combustion of fossil fuel in gasoline and diesel powered vehicles is a major source of aerosol particles in a city. In a street canyon, the number concentration of particles smaller than 300 nm in di...
Computations of the Response of a Wave Spectrum to a Sudden Change in Wind Direction
Wave Spectrum Wind Direction Sudden Change
2009/1/8
The response of a wind-sea spectrum to a step function change in wind direction is investigated theoretically for a sequence of direction changes ranging from 30° to 180°, in increments of 30°. Two sp...
Effect of wind direction on aeolian sand transportin southern tunisia
aeolian transport wind direction southern Tunisia
2008/11/19
Assessment of aeolian transport in three experimental stations in southern Tunisia showed a prevailing wind direction from the east, the southeast and the north over the winds coming from the south an...
Dependence of CO2 advection patterns on wind direction on a gentle forested slope
Dependence CO2 advection patterns wind direction gentle forested slope
2010/1/15
Gravitational flows generated on a gentle slope in stable conditions were analysed at a forested site at Vielsalm in Belgium. There were two distinct situations at the site, one corresponding to verti...
