| Abstract: | Experimental result on wind tunnel simulation of the local wind characteristics at the Beijing Botanical Garden and surface Pressure distribution measurements on the l/l00 model of the Large- scale Greenhouse of Tropical Plants there are introduced in this paper. A mechanism on the local strong wind area around the green house generated under the effect of the downwash flow in the bottom of the Cherry Valley has been demonstrated and the variation of pressure distribution on the greenhouse in different wind directions has been indicated. |
