天气

The factors available to hail formation and development, as the climatic, the synoptic and local circulation characteristics and local factors in northwest China are summarized. The recent achievements in hail research by the radar, satellite, lighting gauge and modeling are summed up. Some key scientific problems needed to be urgently solved and research methods needed to be further developed are pointed out.Keywords : Hail research Climatic and synoptic circulation characteristics Northwest China.

归纳了西北冰雹的天气特征、气候规律，概括了产生冰雹天气的环流形势和诱发冰雹天气的局地因素，综合分析了雷达观测、卫星观测、闪电定位和数值模拟等手段在西北地区冰雹研究领域的新进展，最后指出了西北冰雹研究领域急需解决的科学问题和需要进一步发展的研究手段。

Climate: The prevailing or normal pattern of weather at a place, or in a region, averaged over a long period of time; in contrast to weather, which is the state of the atmosphere at a particular time.

气候：某一地点或某一区域内普遍的或者通常情况下较长时间范围内的平均天气状态；与天气不同，天气是指大气在某一特定时间的状态。

This pilot web site presents OFFICIAL weather forecasts and climatological information for selected cities supplied by National Meteorological Services worldwide.

世界天气信息服务网列出的世界部分城市的官方天气预报和气候信息由各国气象部门提供，它们负责本国的官方天气观测和预报工作。

Comparing size distribution of trace elements at haze weather and the normal weather discovered that,Ca、Ti、Fe、Cr showed significant enrichment in the small size particle at the haze weather:Cu,As didn't have different at such two kind of weather conditions;Zn、Mn、Pb appeared bimodal even trimodal distribution,whose suggested that there were a long distance transmission in originations of such three metals.

对比正常天气下的金属元素的粒径分布，发现：Ca、Ti、Fe、Cr 等元素在灰霾发生时细粒径上有明显的富集： Cu、As 在两种天气条件下区别不是很大：Zn、Mn、Pb 等元素在两种天气条件下均出现双峰甚至多峰分布。由此推断 Zn、Mn、Pb 的来源中可能存在长距离传输。

Changes in the weather can also lead to fluctuations in blood pressure are generally cold weather will increase in blood pressure, hot weather will reduce blood pressure.

天气变化也会引起血压波动，一般是寒冷的天气会使血压升高，酷热的天气会使血压降低。

Having recourse to the cloud model, baaed on the large quantitative of FY-2C images, consisting of five wavelength of spectral data, which were acquired during the period 2006 to 2007 over Asia-Pacific area, the main radiance features of different rain types such as rainstorm, light rain.

最后以2006年7月6日FY-2C中国分区图所示地区对应的FY-2C卫星云图进行降水类型分类为实例，得到不同降水天气对应的云图辐射亮度值特征，并利用分类结果对实况云图进行降水天气的判别，结果表明该方法对大暴雨天气的判别效果良好。

This year, 10 speakers will attend the seminar to talk on topics ranging from how to protect your institution from severe weather, how National Weather Service centers decide to issue weather warnings and watches, the dangers of high winds and lightening, and recaps of the near-disaster weather of last summer that affected Chicago near the Loyola University Campus, northern Illinois, and northern Indiana.

今年， 10个发言者将出席研讨会，讲座，主题包括从如何保护您的机构由恶劣天气，如何国家气象服务中心决定发布天气警告及手表，危险的强风和闪电，和recaps近灾害天气的去年夏天，受影响附近的芝加哥罗耀拉大学校园，伊利诺伊州北部和印第安纳州北部。

At this moment he was lying ill of fever in the clay lands near Curitiba in Brazil, having been drenched with thunder-storms and persecuted by other hardships, in common with all the English farmers and farm-labourers who, just at this time, were deluded into going thither by the promises of the Brazilian Government, and by the baseless assumption that those frames which, ploughing and sowing on English Liplands, had resisted all the weathers to whose moods they had been born, could resist equally well all the weathers by which they were surprised on Brazilian plains.

就在此时，他在靠近巴西的克里提巴的粘土地里，淋了几场雷雨，加上受了许多其它的苦难，病倒了，发着高烧，同时和他一起受难的还有许多其他英国农场主和农业工人，他们也都是因为巴西政府的种种许诺被哄骗到这儿来的。他们依据了那种毫无根据的假设，既然在英国的高原上耕田种地，身体能够抵挡住所有的天气时令，自然也能同样抵挡巴西平原上的气候，却不知道英国的天气是他们生来就习惯了的天气，而巴西的气候却是他们突然遭遇的气候。

Arctic area as a driver and adjustor of global climate, it reflects sensitively to climatic change. It will be significant to do paleo-oceanographic research in Arctic, which could be very helpful to the prediction of future global climate change.

北极作为全球天气变化的驱动器和调节器，对全球的天气变化非常敏感，通过对北极海域古海洋学的研究，将有助于我们猜测未来的全球天气演变趋势。

Although a lot of economic activities are not contributed by weather directly, but the result or course are affected either positively or negatively. For instance, beverage retailer adjusts circulation according to temperature, farmer adjusts way of cultivation according to rural weather report, and umbrella chapmen decide whether to sell or not.

许多经济活动虽不是直接由天气促成，但其结果或进行过程中是受到天气正面或负面影响的，不管是饮料商根据气温调整贩售量、农夫根据农业气象调整耕作方式、雨伞小贩依据大雨特报决定摆摊与否等，皆显示出天气已影响人类经济活动至深。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
