Earthshine and Asteroseismology Telescope (East) Network

Several automated optical telescopes have been setup at appropriate longitudes around the globe to study earthshine variations and asteroseismology. The first telescope has been setup at Teide Observatory, Tenerife, Spain in October 2004. The intensity of earthshine relates to the average of Earth’s albedo, and in turn relates to the global temperature of the Earth. A global network is necessary because each site can measure the earthshine reflected from only a part of the Earth. The network will also be used for asteroseismology study. It can measure photometric variations of pulsating stars. The long-term and continuous measurements allow the accurate determination of mode frequencies of stellar pulsations, which provides information on the properties of stellar interior.

A Possible Transfer Mechanism for the 11-Year Solar Cycle to the Lower Stratosphere

Observational evidence of the 11-year solar cycle (SC) modulation of stratosphere temperatures and winds from the ERA-40 dataset is reviewed, with emphasis on the Northern winter hemisphere. A frequency modulation of sudden warming events is noted, with warmings occurring earlier in solar minimum periods than in solar maximum periods. The observed interaction between the influence of the SC and the quasi biennial oscillation (QBO) on the frequency of sudden warmings is noted as a possible clue for understanding their mechanism of influence. A possible transfer route for the 11-year solar cycle from the equatorial stratopause region to the lowest part of the stratosphere is proposed, via an influence on sudden warming events and the associated induced meridional circulation. SC and QBO composites of zonal wind anomalies show anomalous wind distributions in the subtropical upper stratosphere in early winter. Mechanistic model experiments are reviewed that demonstrate a sensitivity of sudden warmings to small wind anomalies in this region. Various diagnostics from these experiments are shown, including EP fluxes and their divergence and also the synoptic evolution of the polar vortex, in order to understand the mechanism of the influence. Some recent GCM experiments to investigate the SC/QBO interaction are also described. They simulate reasonably well the observed SC/QBO interaction of sudden warming events and appear to support the hypothesis that tropical/subtropical upper stratospheric wind anomalies are an important influence on the timing of sudden warmings.     

可视化技术在分析新型蓄冷材料——笼型化合物（Clathrate）溶解过程中的应用（一）、（二）

混浊液内部的流动，由于微粒子之间的相互作用以及因浊度高不易进行内部观察，所以无论是分析还是可视化实验都相当困难，存在着许多未弄清的问题。通过采用折射率匹配（Refractive-IndexMatching）技术，使透明的微粒子与透明的溶媒的折射率近乎相同，做成一种透明的“混浊液”，从而使混入其中的示踪粒子的运动轨迹能被摄像机捕捉到，并以微粒子的沉降和温度的干涉所引起的流动现象为焦点，利用图像速度测量法来处理分析所拍摄到的可视化图像，成功地获得了定量的混浊液内部的速度场，为进一步揭示混浊液内部自然对流的流动机理提供了实验依据。
