Cold wave and ferocious, press the bottom down! Today the most in this winter "cold" day, daytime maximum temperature 0 ° c, night temperature-5 ° c, accompanied by five or six levels and windy North wind. Meteorological experts said today, whether high or low, were to hit new lows in this winter. Beijing morning news reporters from both the municipal heating group was informed that, in response to the cold current cooling, heating group opened 10 peak boilers, heating heating network management.
Daytime maximum about 0 ° c
Municipal Meteorological Bureau said the cold wave under the influence of strong cold air, featuring wind and temperature, cold air from its peak last night to tonight. North wind and windy period since yesterday afternoon and today, tomorrow, three or four-level wind temperature last night to Thursday. Specific forecasts is today much of the daytime maximum temperatures to fall to around 0 ° c; tonight through Thursday night-time minimum temperatures in the plain areas will be reduced from-4 to-5 ° c, mountain-9 per cent to-10 degrees Celsius. Minimum and maximum temperatures in the city are low in this winter. 25th signal warning of this winter's first cold spell blues, still persist.
Winter time is October 30 this year, the capital city, 2 days earlier than the year round. Southern Observatory 30 average winter time on November 1. After the recent cold weather this winter, cooling the sharpest and most powerful again.
20, peak boilers always enabled
Meet the howling North wind, spare peak boiler startup capital along with "heating". Open boiler belong to 10 spikes shuangyushu, zuojiazhuang, fangzhuang three heating plants. Municipal Heating group official Beijing morning news reporter that at short after this cold spell of weather forecasting from 25th night, Spike gradually turn on the boiler, 26th, has opened 10. Peak boiler starts, can be driven directly inside the city's heating system to heat up, its warming effect than in the urban areas surrounding large effect to raise the water temperature in the power plant to heat up more quickly and directly.
In addition, the municipal heating group are coordinated around the city's major thermal power plants to improve the heating water temperature. Current trunk heating water temperature is 90 ° c before the heat rising to the current 100 ℃, district heating heat station branch line water temperature has been maintained at between 47 ° c to 50 ° c. Since a heating main line pressure, water temperature can continue to improve. There are spikes in the city boilers 30, not 20 peak boilers will also be opened depending on the weather temperature lower and gradually opened today.

National condition
Southern cities most low temperature breaking the freezing point
The strong cold air not only will pull capital into very cold. Issued by the Central meteorological observatory at 10 o'clock yesterday for this winter's first cold snap blue alerts. This day, most of East-Central China will cool the high winds, temperatures in some areas to break record lows this winter, Hefei, Wuhan, Nanjing, Hangzhou, the minimum temperature fell below 0 degrees centigrade.

寒潮凶猛，压箱底的羽绒服走起！今天迎来今年入冬以来最“冷酷”的一天，白天最高温0℃，夜间最低温-5℃，伴有五六级凛冽北风。气象专家称，今天无论最高气温还是最低气温，均将创今年入冬以来新低。北京晨报记者同时从市热力集团获悉，为应对此次寒流降温，热力集团已开启10座尖峰锅炉，为供热网管加温。
白天最高0℃左右
市气象局表示，此次寒潮天气受强冷空气影响，特色是大风和强降温，冷空气巅峰在昨夜到今夜。北风凛冽的时段从昨天下午到今天，明天还有三四级北风；强降温时段在昨天夜间到周四。具体预报是，今天白天大部分地区最高气温将降至0℃左右；今夜到周四夜间平原地区最低气温将降至-4到-5℃，山区将降至-9到-10℃。本市最低和最高气温均将创今年入冬以来新低。25日发出的今冬首个寒潮蓝色预警信号，还在持续生效。
今年京城的入冬时间为10月30日，比常年偏早2天。南郊观象台30年平均入冬时间为11月1日。此次寒潮天气为今年入冬之后最强、降温最剧烈一次。
20座尖峰锅炉随时启用
迎接呼啸的北风，备用尖峰锅炉随之启动为京城“加温”。开启的这10座尖峰锅炉分属于双榆树、左家庄、方庄三座供热厂。市热力集团相关负责人向北京晨报记者透露，在接到此次寒流的气象预报后，从25日晚间，尖峰锅炉就陆续开启，26日晚7时，已经开启10座。尖峰锅炉的启动，将可以直接带动城区内部的热网升温，其升温效果比城区周边大型热电厂提高出水温度的升温效果要更快更直接。
除此之外，市热力集团也在协调城区周边的各大热电厂提高供热水温。目前供热干线的水温已经从供热前的90℃上升到了目前的100℃，从换热站到小区的供热支线水温一直维持在47℃至50℃之间。由于供热干线内有一定压力，因此水温还可以继续提升。本市目前共有尖峰锅炉30座，尚未开启的20座尖峰锅炉也将视今天天气温降低情况而逐步开启。

全国情况
南方多个城市最低温破冰点
这次强冷空气不独将京城拉入天寒地冻。中央气象台昨天10时发布今冬首个寒潮蓝色预警。今明两天，我国中东部大部地区将出现大风降温，部分地区的气温将创今冬新低，合肥、武汉、南京、杭州的最低气温将跌破0℃。
