This paper makes an analysis of the Doppler speed charts of clear weather and the echoes of large-area precipitation. It also singles out the Doppler speed charts of typical wind fields. In addition, this paper analyzes Doppler radars detecting process of the strong convection current weather system. It also conducts a thorough analysis of Doppler echo features of some hazardous weather, such as cell storm and downward storms. Based on this research and analysis, the paper reaches some important conclusions concerning the detecting methods using Doppler radar and the analysis of the information gathered by Doppler radar.

The results suggest that under the background of global warming, the researches on the mechanism and variation of snow-storm and freezing rain should be strengthened, especially the researches on their premonitory characters; modern detect technique and instrument should be used to improve the ability of monitoring snow-storm and freezing rain, and skills and methods for forecasting snow-storm and freezing rain should be established and improved.

认为：在全球气候变暖的背景下，要加强雨雪、冰冻天气形成机理与变化规律的研究，特别是要加强其发生的前兆性研究；要充分利用现代先进的探测技术和手段，提高对雨雪、冰冻天气的监测能力；要建立和完善对雨雪、冰冻灾害天气时间发生、发展的预报技术和方法。

But because the guidance thought that climate is the synthesization of weather is wrong, the short-term climate prediction is not so successful yet in the past 100 years.

在"气候是天气的综合"这一错误思想的指导下，每一次短期天气预报的成功都引出了短期气候预测的热潮，相应地出现了大型天气学、超长波控制论和短期气候的数值模式预测方法。

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。

A great deal of thin sand in the weak convergence zone went to Lhasa along with the western high-level air current.

最后，给出了拉萨浮尘天气预报的思路，为拉萨浮尘天气的准确预报提供了一些参考信息。

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。

Careful analysis on NBE can facilitate nowcasting of severe weather events and further understanding of their evolution. After detailed study on three cases concerning with NBE, it is concluded:(1) NBE triggered by fast moving echo in upstream is an important indication of disastrous wind;(2) NBE can develop into severe storm under proper conditions. There are often two stages during this kind of growing: the first is developing of initial echo, the second is snap growing of echo core;(3) Doppler radar reflects outflow of downburst as a nearly ringed NBE. Inside look on downburst can be obtained combining NBE with other data.

文章结合发生在上海的3次强对流天气个例，详细分析了弱窄带回波在分析和预报强对流天气中的作用，得出以下结论：（1）上游移动强回波的出流边界导致的弱窄带回波是大风预警的重要判断参考；（2）在合适的层结状态和抬升条件下，弱窄带回波会强烈发展，并导致局地雷雨大风，这类强对流天气的发展有两个比较重要的阶段：弱窄带回波上初始回波的发展和回波跃增；（3）下击暴流造成的地面出流在雷达回波上表现为近似圆弧的弱窄带回波，这种弱窄带回波与其他雷达观测特征以及地面观测相结合，有助于对产生下击暴流的对流云的发生发展过程进行细致分析。

Housewives listen to the weathermen'spredictions and wait for the weather to improve before they wash a lot clothes.

家庭主妇收听气象预报员对天气的预测，等待天气变好后再大量浆洗衣服。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
