1、电动三轮车及充电桩生产项目运营期环境影响评价1.1 大气环境影响评价1.1.1 评价区域气候特征根据环境影响评价技术导则大气环境（HJ222008）要求及模式需要，本次大气预测采用衡水市地面气象观测资料和高空气象探测资料。根据导则要求，本次评价采用衡水市气象站2015年全年逐时常规地面气象数据，该站点编号54702,地理位置为东经115。42。北纬37。441地面气象数据包括风向、风速、总云量、低云量和温度，其中，风向、风速、温度为每日24次观测数据，总云量、低云量为每日3次观测数据，在软件数据处理过程中，对非24小时逐时观测的总云量和低云量进行了插值处理。衡水市气象观测站与本项目厂区距离小于

2、50km,且与评价范围的地理特征基本一致，因此，可不再进行补充地面气象观测。（1）常规气象资料统计与分析本项目常规气象资料统计与分析采用衡水市气象站提供的地面气象数据，分别对温度、风速、风向、风频及主导风向等气象因素进行分析。衡水市2015年月平均温度变化情况见表1.1-1和图1.1-1o表1.1-1衡水市2015年月均温度的变化统计分析表月份123456789101112全年温度-2.0.9.112124212521157.0.13.4880.2.8.3.6.6.1.2849图111衡水市2015年月均温度变化图衡水市2015年各月平均最大风速出现在4月，为2.72ms,最小风速出现在1月，
