Anomalous extensive drought and megatherm weather from 1998 autumn to 1999 spring is diagnosed,and it is found that El Nino and La Nina events are the important climatic background resulting in anomlous climate in Guangxi.Exceptional weakness of cold air intruding into Guangxi,positive anomalies of the heigh field over the Qinghai-Xizang plateau,weakness of the Indochina trough,a sustained strong subtropical high,and less and weak tropical cyclones influence are main contributing factors to the long sustain...

对广西1998 年秋至1999 年春出现的大范围干旱伴高温的异常天气进行了诊断分析，发现厄尔尼诺与拉尼娜事件是导致广西气候异常的重要气候背景，入侵广西的冷空气异常偏弱，高原高度场偏高，印缅槽偏弱，副热带高压持续偏强，热带气旋影响偏少，强度偏弱，是导致广西1998年秋至1999年春罕见的长时间高温、少雨、异常干旱的主要原因。

本文试以青藏高原唐古拉山冬克玛底冰川表面和南极冰盖表面连续的至少一个整年的资料分析，揭示高亚洲大陆型冰川表面及南极冰盖表面气候特征的变化规律及其能量形成机制。

Mirabilite and sand wedge are the markers of cold\|dry climatic environment.

芒硝和砂楔是冷干气候环境的典型标志。

According to regionalizing indicators of average annual accumulated temperature above 20℃, average annual freezing index, precipitation in freezing period and average annual precipitation in nonfreezing period, the macro layer of the regionalization, China climatic regionalization for highway, were suggested through methods of cluster analysis, division based on indicator and layers superposing, which included 10 first-level regions and 24 second-level regions. It summarizes that climate of China affects highway in macro level.

利用多指标系统聚类分析、指标划分和图层叠置等方法，以累年年≥20℃积温、累年年冰冻指数、累年年非冰冻期降水量以及累年年冰冻期降水量为区划指标，对处于方案体系宏观层的中国公路气候区划进行了具体划分，提出了由10个一级区、22个二级区构成的两级区划方案，为了解中国气候对公路综合影响的异同性以及影响程度差异提供了一个平台。

They have several meters of paleosol developed on the top of overbank silt, suggesting that the abandonment of each terrace due to river incision occurs during the transition from glacial to interglacial climates and there may be a link between the production of terraces and glacial-interglacial climatic cycles. However, it is not every glacial-interglacial transition during the last 1,240ka that terrace can form and preserve.

黄河各阶地河漫滩顶部都有一层古土壤发育表明黄河下切形成阶地发生在古土壤开始发育的冰期向间冰期的过度阶段，但是并非1，240ka以来的每次冰期—间冰期的气候交替都能引起黄河下切形成阶地。

Results indicated that population quantities of dominant species were seriously influenced by extreme climatic events:safety of passerine populations were influenced by sandstorms,hailstones and rainstorms;safety of migratory bird populations mainly by sandstorms hailstones and rainstorms,safety of rodent populations by rainstorms and safety of goat popula...

极端天气气候对优势物种数量影响严重。雀形目种群安全主要受到沙尘暴、冰雹和暴雨的影响较大；迁徙鸟类种群安全主要受到沙尘暴、冰雹和暴雨的影响较大；啮齿类种群安全主要受到暴雨的影响较大；岩羊种群安全受到沙尘暴、冰雹、暴雨和降雪的影响。

By using of NCAR/NCEP reanalysis daily average data from 1950 to 2002 and daily rainfall of 355 stations in east China from 1957 to 2000 , whole layer vapor transportation fluxes of all globe are calculated , climatic characters of East-Asia pentadactyl vapor transportation in summer are analysed , differences of pentadactyl vapor transportation in strong vapor transportation years and short ones , and relations of vapor transportation in East-Asia and rainfall in east China.

使用1950～2002年NCAR/NCEP再分析逐日平均资料和1957～2000年我国东部355个站点的逐日降水量资料，计算了全球整层水汽输送通量，分析了东亚地区大尺度候平均水汽输送时空分布的气候特征和年际、年代际变化特征，研究了水汽输送强、弱年候平均水汽输送的差异，讨论了东亚地区各候水汽输送与我国东部降水的关系。

Thirdly, the influence of climatic factors on phenological shift was complex.

第三个特点是植物物候期变化与气候因子间呈现明显相关关系。

Therefore, to predict phenological shift in tropical regions in respond to climate change with a single climatic factor would increase the risk of obtaining wrong results.

因此，在热带地区采用中高纬度地区的方法，使用某个单独气候因子来预测热带植物物候期的变化可能导致失真的结果。

They have quite a lot of work to do.

他们有许多工作要做。

Let us give you a more elaborate example of this process.

让我们给你这个过程的更多的详细例子。
