The phrase "downwind direction" is correct and usable in written English.
This phrase generally refers to the direction that the wind is blowing towards, so it can be used any time you are describing the direction of the wind. For example: "The birds were flying in the downwind direction, following the breeze."
The monitoring stations in downwind direction illustrated a logarithmic decrease of PM with distance.
In the downwind direction, pollutant concentrations decreased rapidly from roadside and by some tens of metres reached relatively constant values.
It is observed that the horizontal extent of visible flame length is affected by the wind flowing in the downwind direction of jet fire.
Then at 2 37 p.m., an evacuation of another area was ordered, beginning at the two-mile line and extending in the downwind direction for several miles, with another 76,145 residents told to move.
Both aeroelastic tests and pressure measurements were performed on the cylinder with forward inclinations (inclined to the upwind direction), a vertical attitude, and backward inclinations (inclined to the downwind direction) in a wind tunnel.
Both aeroelastic tests and pressure measurements were performed on the cylinder with forward inclinations (inclined to the upwind direction), a vertical attitude and backward inclinations (inclined to the downwind direction).
The turbulence noise is dominant at low frequencies and is primarily observed in the upwind and downwind directions.
Researchers designed a horizontal grid of sampling locations centered at the tracer plume source, with the tower positioned at 10 m and 30 m in both upwind and downwind directions, and the MTRS spaced at 50 m and 90 m downwind and 90 m upwind.
The CO2 flux was estimated integrating the concentration values (>650 ppm) inside the black dashed lines, close to the main fumaroles and downwind dispersal direction.
The CO2 flux was estimated integrating the concentration values (>600 ppm) inside the black dashed lines, close to the main fumaroles and downwind dispersal direction Fig. 5 concentrationsions (ppm) map at "Furnas Village" survey (using TDL).
In this study, two symmetrical multi-foil shields were designed to minimise spray drift in both upwind and downwind travel directions.
