2012年进入7月以来,灾害性天气频发,中国大部分地区不同程度地出现了今年最大范围的强降雨,部分地区还出现了冰雹、龙卷风等强对流天气.这些极端灾害性天气在给人民群众生命财产造成巨大损失的同时,也对各个城市交通系统进行了危机测试,不幸的是大多数城市的测试结果并不理想.以北京为例,"721"暴雨导致全市25处道路积水,还有多处道路深度积水.积水道路绝大部分都位于南城:南二环、南三环和南四环都出现因水断路的现象,南城交通也出现异常的大拥堵.

在户外运动时,驴友们面临的首要问题就是天气的变化,尤其是到一些高海拔地区,很可能在一天内经历风、雨、雹、雪4种天气的变化,因此对衣着的要求格外高,防风、透气、保暖等功能,一个都不能少.但是,在选购户外运动服装时,除了要关注其功能外,更重要的是实用.

针对目前持续的高温天气,为切实保障广大宣纸生产员工的身体健康,近日,泾县中国宣纸集团公司积极采取多种措施,着为做好防暑降温工作.

气象新闻报道区别于天气预报,最重要的一点就是新闻报道注重人文精神,体现人文关怀.关注人的生存、人的权益、人的发展,气象新闻因为具有这样的视角,才变得更具价值.一、多角度营造人文关怀的氛围1.把气象新闻安排在醒目的位置《陕西日报》没有专门的气象专版或气象栏目,但编辑会尽量把气象新闻放在醒目的位置上.当发生重大气象灾

Migrating landbirds are known to follow coast lines and concentrate on peninsulas prior to crossing water bodies, es- pecially during daylight but also at night, creating enhanced potential collision hazards with man-made objects. Knowing where these avian migration "hot-spots" occur in time and space is vital to improve flight safety and inform the spatial planning process (e.g. environmental assessments for offshore windfarms). We developed a simple spatial model to identify avian migration hot- spots in coastal areas based on prevailing migration orientation and coastline features known, from visual and radar observations, to concentrate migrating landbirds around land masses. Regional scale model validation was achieved by combining nocturnal passerine movement data gathered from two tier radar coverage (long-range dual-polarization Doppler weather radar and short- range marine surveillance radar) and standardised bird ringing. Applied on a national scale, the model correctly identified the ten most important Danish coastal hot-spots for spring migrants and predicted the relative numbers of birds that concentrated at each site. These bird numbers corresponded well with historical observational data. Here, we provide a potential framework for the es- tablishment of the first three-dimensional avian airspace sanctuaries, which could contribute to more effective conservation of long-distance migratory birds [Current Zoology 60 (5): 680-691, 2014].
