Snow is hard to see "cold enough"
To see snow in Beijing this year why so hard? Beijing professional meteorological experts said Zhang Mingying, Beijing's recent poor moisture conditions.

新京报讯 (记者赵力)昨日傍晚，有网友称“回龙观下雪了！”连同这句话的还有一张雪景照片。消息不胫而走，人们纷纷四处打听，北京的第一场雪终于来了吗？
很快，人们发现这只是一个恶作剧，昨天的北京没有下雪。但是人们等了很久的“初雪”将至，气象预报称，今天(17日)凌晨起到上午北京将有小雪。
雪花半夜来“敲门”
据北京市气象局高级工程师张庆元称，从地区气象资料分析看，昨晚北京高空已经有了偏湿气流，天气形势越来越向有利于降雪的方向发展，随着空气湿度的增加，昨天夜间天气转阴，云层也逐渐加厚，后半夜将出现大家盼望已久的降雪。
“降雪将于明天中午停止，基本上是小雪，降雪量在一毫米以下。”张庆元说。然而这场久违的雪只是昙花一现。中国天气网对北京未来几日的天气预报显示，该场小雪过后，一周内天气还是主要以晴为主。
北京市交管部门提醒，在降雪同时气温有明显下降，预计部分道路可能会出现结冰情况，雪后路面湿滑，提示市民尽量减少自驾车出行，同时为避免明天早间道路拥堵，请尽量提早出行时间或选择公共交通出行。
初雪难见因“不够冷”
今年北京看雪为何这么难？北京市专业气象台专家张明英表示，北京近期水汽条件较差。
张明英说，北京水汽输送来源主要有两个，一是来自南海的水汽。二是偏东风吹来渤海湾水汽的回流。从近期的环流形势来看，北京主要受到偏北风的影响，导致两个水汽“通道”全部受阻。
此外，中科院大气物理研究所研究员王庚辰表示，“见雪难”的另一个原因是到目前为止冷空气势力偏弱，“冷得还不够。”他称，对北京来讲主要的降雪还是集中在12月底到次年1月份。
此前，市气象部门也曾表示，今冬初雪迟迟未到并不异常。气象资料显示，北京常年12月的降水量不足2毫米，降水日数也只有1.7天，历史上12月出现降雪的天数和降雪量都很少。
应对
夜间降雪早晨清完
新京报讯 (记者饶沛)北京迎来初雪，环卫部门已根据雪情制定了相应的作业预案，在降雪量不是特别大的情况下，夜间降雪在早高峰前已完成清除。
昨晚，记者从市市政市容委和市环卫集团了解到，根据本市的总体安排，今年将以机械除雪为主，以便减少融雪剂的使用。桥区上下坡、过街天桥等地段，还是将视情况喷撒融雪剂。
