A. maximum wind frequency is upwind to B., minimum wind frequency, wind direction C. minimum wind frequency above wind direction D. on both sides of prevailing wind direction Answer: C, take P144 The question of knowledge is about climatic conditions. The question of knowledge is about climatic conditions. In the planning of urban land use, the industrial area is usually located in the leeward of the residential area. The minimum wind frequency, wind frequency, seasonal variation of the prevailing wind direction and wind speed should be taken into account. Such as: the only one with the prevailing wind direction, and the relative direction of minimum wind frequency conversion, or the minimum wind frequency of wind direction and the prevailing wind direction angle greater than 90 degrees, while the industrial land should be put in the wind above the minimum wind frequency, residential area is located in the downwind. When there is a trend of two directions in the whole year, it is necessary to avoid polluting industries in any prevailing wind direction.
