Beijing will welcome this day fog haze (picture) | | severe pollution haze | Observatory _ news
This haze "crazier"
Continuous pollution trap high levels of pollution in urban areas would suffer in the morning afternoon temperatures tomorrow will reach 26 ° c
Legal evening news (Xinhua Zhao Yingyan Bai Bing) recently, spring was riveting as "female man", the temperature kept high jump. Today, the highest temperatures reach 22 ° c. But don't worry that the haze here this day again, "clogging".
This morning, the temperature reaches 7.3 degrees Celsius in southern observatories, but due to poor light and haze enveloped the lighting conditions change, thus warming the feet become slow. Therefore, people who go out in the morning, a little bit cold feeling. According to the municipal meteorological station forecast, today's urban high rises to 22 ° c, after noon, warming will open the acceleration.
Today's warming temperatures next week's "prelude". It is understood that next week average temperatures around 15 ° c is far higher than the same period in history. The day after tomorrow, will reach 26 ° c maximum temperature in urban areas, like summer.
Although temperatures to create an atmosphere of warmth, but this day haze revolted.
At 8 o'clock in the morning today, a reporter from the environmental monitoring center, the city's air quality is under severe pollution hanging over. Among them, six districts of PM2.5 concentrations for 238 mg/m, for most all over the city. Northwest point 195 mg/m for all the light in the city.
It is estimated that today's pollution levels will become increasingly serious. Poor diffusion conditions continued the next few days, heavy pollution, the public should reduce outdoor activities. As of press time, the city has not been heavy pollution alert has been issued.
Explanation why the temperatures are higher than in previous years?
Municipal meteorological observatory chief forecaster described Yu Bo, next week is mainly the high temperature caused by cold air forces is not strong.
Starting last winter, although Beijing frequently affected by cold air harassment, but because of the weakness of the forces, the average temperature in winter is-2.6 ° c,-3.9 ° c than the perennial high 1.3 degrees centigrade.
And in the spring, according to warmer climate characterized by a warming of the season, because there is no cold air pressure, temperature is more like a duck to jump high.
Haze and fight again in the spring?
Meteorological experts, as spring begins to mimic the night gradually shorter, the Sun is warming the Earth's surface gets longer enabling air flow. Therefore, under the same weather conditions, spring conditions are significantly better than the proliferation of winter, fog and haze levels will be weaker than winter, but doesn't guarantee that all "disappeared".
This haze of the day mainly because there is no cold air activities, caused by atmospheric static stability.

北京今明两天将迎雾霾天气(图)|重度污染|雾霾|气象台_新闻资讯
今明两天 雾霾“添乱”
上午城区陷重度污染 将遭遇连续污染天 午后气温升高 后天将达到26℃
法制晚报讯 (记者 赵颖彦 白冰) 近来，春姑娘铆足了劲儿变身为“女汉子”，气温一个劲儿地蹿高。今天，最高温度将达22℃。但不让人省心的是，雾霾今明两日又来“添堵”。
今天早晨，南郊观象台气温达到7.3℃，可由于轻霾笼罩光照条件变差，因此升温的脚步变得慢吞吞的。因此，早晨出门的市民会有点冷飕飕的感觉。据市气象台预报，今天城区最高气温将升至22℃，中午过后，升温将开启加速度。
今天的气温只是未来一周升温的“前奏”。据了解，未来一周平均气温将在15℃左右远高于历史同期。后天，城区最高温度将达到26℃，恍如初夏。
虽然气温给力营造出春暖花开的气氛，但无奈今明两天雾霾又出来作乱。
今天上午8点，记者从环保监测中心看到，全城的空气质量都处于重度污染程度的笼罩之下。其中，城六区的PM2.5浓度为238微克/立方米，为全城最严重。西北部的浓度为195微克/立方米，为全城最轻。
据预计，今天下午的污染程度将会越来越严重。未来几天扩散条件持续较差，污染较重，市民应减少户外活动。截至记者发稿时，本市尚未发布重污染预警。
释疑 为何气温比往年偏高？
市气象台首席预报员于波介绍，未来一周气温偏高主要是冷空气势力不强所致。
从去年入冬开始，虽然京城频频受到冷空气骚扰，但由于其势力偏弱，这个冬季的平均气温为-2.6℃，比常年的-3.9℃偏高了1.3℃。
而到了春季，根据气候特点就是一个升温回暖快的季节，由于没有冷空气的打压，气温更是如鱼得水地蹿高。
春季雾霾又杀回马枪？
气象专家介绍，由于春天开始逐渐昼长夜短，太阳为地球表面增温时间变长有利于空气流动。因此，在相同的气象条件下，春天的扩散条件明显好于冬天，雾霾的程度将比冬天弱一些，但并不能保证完全“绝迹”。
今明两天的雾霾主要因为没有冷空气活动，大气相对静稳造成的。
