Half of Beijing meteorological station under the influence of high-rise | | | Beijing Meteorological Observatory tower to play the role _ news

Reporter (reporter Zhao Tingting) Lin Keqing, Deputy Mayor of Beijing yesterday at the city's meteorological modernization work conference revealed that currently more than half of the city's national meteorological observatory had been affected to varying degrees, "damaged", due to environmental damage forced relocation of 5 stations.

According to Lin Keqing on, Beijing Meteorological observation environmental protection weak and more than half of the city's State Meteorological Station on varying degrees of "breaking", due to environmental damage forced relocation of 5 stations; the city's only two weather radar was blocking for newly constructed high-rise buildings, the city's only State reference climatological station was seriously affecting the environs of tall buildings in the vicinity, hard to play the role.

According to the Beijing Meteorological Bureau, said people call "destruction" is not primarily damage in the ordinary sense, but during the process of urbanization in Beijing, the construction of a large number of high-rise buildings, around the meteorological station on the environment creates a "damaged". "The meteorological stations are primarily used to measure data such as wind speed, humidity and temperature, if built around many high-rise buildings, had an impact on wind and wind speed, and buildings will lead to detection radar blind spot, Observatory measured data may be inaccurate, thereby affecting the study on future weather conditions. ”

According to December 1, 2012 up purposes of meteorological facilities and meteorological detection environmental protection regulations under, in national General weather station observation field around 800 m detection environmental protection range within prohibited built height over from observation field distance one-eighth of buildings, and structures; in observation field around 200 m range within prohibited set dump, and sewage mouth, interference source; in observation field around 100 m range within prohibited built railway; in observation field around 50 m range within prohibited dug built reservoir, , And forbidden in the observation field within a range of around 30 meters built roads, planted trees and crops in more than 1 m in height, and so on.

Industry sources, some still couldn't solve surroundings "breaking" issues, relocation of government departments can coordinate to help meteorological observatory site again, but it's not a simple thing. "Meteorological observatory site on the surrounding environment is very high, city-wide distribution, site settings as well as a certain degree of representativeness, surrounding within a certain range cannot be blocked. "The person said, by contrast is more important to establish a long-term mechanism, urged meteorological stations around the planning and construction of communication and meteorological services, and then, to minimize the damage to all meteorological stations.

In addition, Lin Keqing revealed that current meteorological forecasting and warning in the capital core technological level it is difficult to meet the precise forecast of demand, significantly lag behind developed countries and advanced countries. Regional numerical weather prediction models in foreign countries have reached a resolution of 1 km, 1 hour, there are only 3 kilometers away from Beijing, the 3-hour resolution while the Beijing district is warning business start-ups, disaster warning information release capacity is insufficient.

北京半数国家气象观测站受高楼影响作用难发挥|北京|气象观测站|高楼_新闻资讯

　　本报讯(记者赵婷婷)北京市副市长林克庆昨日在全市气象现代化工作会议上透露，目前全市一半以上国家气象观测站遭受到不同程度“破坏”，5个台站因环境破坏被迫迁建。

　　据林克庆介绍，北京气象观测环境保护不力，全市一半以上国家气象观测站遭受不同程度“破坏”，5个台站因环境破坏被迫迁建；全市仅有的两部天气雷达因附近新建高楼被阻挡，全市唯一国家基准气候站因附近的高层建筑严重影响探测环境，作用难以发挥。

　　据北京市气象局相关人士介绍，所谓的“破坏”主要不是普通意义上的破坏，而是指北京在城市化发展的过程中，兴建了大量的高楼大厦，对气象观测站周边的环境造成了“破坏”。“气象观测站主要用来测风速、湿度和温度等数据，如果周围建了很多高层建筑，对风力和风速造成了影响，而且高楼还会导致雷达出现探测盲区，这样一来观测站测得的数据就可能不够准确，进而影响到对未来天气情况的研判。”

　　根据2012年12月1日起施行的《气象设施和气象探测环境保护条例》，在国家一般气象站观测场周边800米探测环境保护范围内禁止修建高度超过距观测场距离1/8的建筑物、构筑物；在观测场周边200米范围内禁止设置垃圾场、排污口等干扰源；在观测场周边100米范围内禁止修建铁路；在观测场周边50米范围内禁止挖筑水塘等；在观测场周边30米范围内禁止修建公路、种植高度超过1米的树木和作物等。

　　业内人士透露，对于一些现在还没法解决的周围环境“破坏”问题，政府部门可以协调帮助气象观测站重新选址搬迁，但这不是一个简单的事情。“气象观测站选址对周边环境的要求很高，要在全市范围内分布均匀，站点设置还要有一定的代表性，周边一定范围内不能有遮挡等。”该人士表示，相比之下更重要的是应该建立一种长远机制，督促气象观测站周边的规划和建设与气象部门沟通后再进行，尽量减少对气象观测站的破坏。

　　此外，林克庆透露，目前首都气象预报预警核心科技水平难以满足精细化预报需求，明显落后于发达国家和先进地区。如区域数值天气预报模式国外已达到1公里、1小时分辨率，北京目前只有3公里、3小时分辨率；而北京分区县预警业务则刚起步，灾害预警信息发布能力不足。
