At low-layer wind direction is Northeast, wind speed decreased with the altitude.
低层吹东北风，随着高度增大，风速减小。
The wind speed trends for the winter and spring, the troposphere, the lower wind speed decreased significantly, the stratospheric wind velocity increased significantly.
各季风速变化趋势为冬季、春季对流层中、下层风速下降显著，平流层风速风速上升显著。
The beneficial effects are that the space occupying of the evaporator of the air-conditioner is decreased, the structure is more compact, and the wind speed at the air outlet is uniformly distributed.
有益效果是减小空调装置蒸发器占用的空间，使其更加紧凑，出口风速分布均匀。
