The change of volcanic glasses in core sediment nearly is the same as that of surficial sediment, the layer number of volcanic glass is more and the contents are higher in the deep-sea basin.

菲律宾岛弧火山带、南海深海盆火山喷发以及印尼岛弧火山带是南海火山玻璃主要源区，火山玻璃搬运和沉积主要受台风、越赤道气流和环流的影响和控制。

Results demonstrate that the MCC develops in a weak baroclinic environment, a 850 hPa horizontal wind shear line with a vortex dominated in the low levels and an anticyclone in upper levels, without barocli...

结果表明，MCC发生在较弱的斜压环境里，对流层低层有明显的天气系统如切变线、中尺度低涡，中层可以没有低压槽参与，高层则出现在反气旋环流里。

The sinking of the high potential vorticity is related to the lower vortex and the rainfall increasing.

北支环流圈的加强以及动量下传使暴雨区北部低层的北风分量维持。

From 1997 to 1999,Gregory scheme succeeds in simulating the basic character of summer rainfall in china, i.e., there are drought in HuaBei and most north province of china in 1997 summer, a heavy flood in Yangtse River valley in 1998 summer and waterlog in south and drought in north of china.

改进后的Gregory方案不仅模拟出了中高纬环流形势的演变过程、西太平洋副高的强弱变化，包括副高的进退和北跳；而且模拟出了98年夏季我国长江流域的大范围降水。

But what's the main reason for the wattless circumfluence in Gansu power grid?

那么，甘肃电网内无功环流存在的主要原因是什么？

What's more, when the transformers in ringed networks are not matching, it will cause the ringed network a loop potential, then the circulating power is existed which also produce wattless circumfluence.

造成无功环流的原因各不相同，有的源于规划，有的是由于管理体制，有的由于运行方式，有的只是环网中各变压器的变比不匹配引起环网中存在环路电势，进而引起循环功率。

With the climography and MICAPS conventional weather chart from 34 meteorological stations ,the spatiotemporal distribution and weather system types and motion path of hail are analyzed.

利用重庆34个县1960-2004年的气象志、县志资料及1980-2004年的MICAPS资料，对重庆冰雹的时空分布特征、环流背景、冰雹路径等进行了综合分析，对重庆人工防雹提出了一些对策建议。

Using the 6 stations precipitation data in the Sanxia area and weather chart data from October to January during 1961—1994,the prior indexes of regional severe precipitation in Sanxia area are analysed under 500hPa circulation of "big U"pattern.

利用三峡地区东部6个站1961—1994年10月—1月的逐日降水量资料和逐日历史天气图资料，统计分析500hPa环流形势呈"大U"型的条件下，三峡地区有无区域性强降水的前期指标，并用1995年资料进行检验，1996年资料进行试报。

In the article, we analysised the rainstorm process using conventional information, encryption data, strength ,speed and wind profile data of Doppler radar, discussed the atmospheric circulation system in the westing process of the subtropical high; revealed the different reasons caused two heavy precipitation (more than 10 mm per hour) and the possibility of small and medium-scale system existed, displayed the vertical distribution of the wind field over the stations in the rainstorm process and the close relationship between the transmission., strengthen of the level air-jet and the heavy precipitation, and then proved that the heavy precipitation was caused by the transmission and strengthen of the low-level jet.

利用常规资料，加密观测资料，多普勒雷达强度、速度和风廓线资料等对本过程进行周密细致的分析。探讨了在副热带高压西进过程中与之相配合的大气环流形势和影响系统；揭示了造成两次强降水（1小时大于10 mm以上）的不同原因和中小尺度系统存在的可能性；展示了暴雨过程中测站上空垂直风场的分布特点以及风廓线高低空急流下传和加强与强降水的密切关系，证明了强降水的产生主要由低空急流的下传和加强引起的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
