An of the degree to which air vibration levels will be affected by the effects of meteorology requires that temperature, wind speed and wind direction be measured or evaluated both at the surface and at levels above the ground	评估空气振动能级受气象效应影响的程度、需要测量或评定地面的以及地面上空的温度、风速和风向
Evaluations of meteorological effects require that the air temperature and wind velocity be known at levels above the ground,preferably up to 900 metres	要想评价气象影响、务必要知道地面上空并且最好在900 米以上的大气温度和风速
Experience to data has shown that at distances of up to 20 km from mine sites,it is desirable to know details of temperature and wind velocity at levels up to 900 meters	迄今的经验表明、在距矿场20公里的范围内、需要知道900米高空温度和风速的详细情况
