  flux transfer
At 4.2K the SQUIDs show a maximum voltage of flux transfer function (?V/??)max=870 μV/Ф0 and a good periodicity of theV-? modulation up to 20Ф0 without any sign of hysteresis.
      
Role of interchange instability in flux transfer event origin
      
The first data show that the iono-spheric signature of flux transfer events occur up to 300 km equatorward of regions showing the HF characteristics of the ionospheric cusp.
      
Whilst larger flux transfer events are seen, on average, every 7 min, many much smaller and short-duration events have been identified.
      
On one occasion DMSP data have been used to show that at least four flux transfer events are occurring simultaneously at the edge of the cusp over 2 h of MLT.

Transfer of radiation through cirrus consisting of non-spherical ice crystals randomly oriented in a horizontal plane (2D model) is solved by using the discrete-ordinates method. The dependence of the scattering parameters on the incident angle caused by horizontal orientation of ice crystals is approximated by the Legendre polynomial expansion of zero and second order. The scattering phase function is represented by means of the analytic Henyey-Green stein function with an asymmetry factor dependent on the...

Transfer of radiation through cirrus consisting of non-spherical ice crystals randomly oriented in a horizontal plane (2D model) is solved by using the discrete-ordinates method. The dependence of the scattering parameters on the incident angle caused by horizontal orientation of ice crystals is approximated by the Legendre polynomial expansion of zero and second order. The scattering phase function is represented by means of the analytic Henyey-Green stein function with an asymmetry factor dependent on the incident zenith angle. The model is employed to determine the radiative flux properties and the intensity distribution of cirrus for both solar and thermal infrared radiation. Comparison of the 2D cloud model with the conventional 3D cloud model, i.e., randomly oriented in a three-dimensional space, shows that the preferential orientation of ice crystals has a substantial effect on the cloud solar albedo. The difference in the cloud abledo computed from the two models can be as large as 8% for a cirrus of 2 km thickness. On the thermal infrared side, the difference in the upward radiances using 2D and 3D models is also significant. However, the IR flux emission for cirrus is less affected by the orientation of ice crystals. In the light of these results, it appears that the preferential crystal orientation may be one of the dominate factors determining the solar albedo of cirrus and may have significant effects in the sounding of the cirrus composition and structure from infrared wavelengths.

本文用分离坐标法求解辐射通过卷云的传输,该卷云由在水平面内随机取向的非球形冰晶所组成,即“二维卷云模式”。文中用零阶和二阶Legendre多项式的展开式来近似表示由于冰粒子水平取向所引起的散射参数随入射角的变化。散射相函数由解析的Henyey-Greenstein函数表示,其不对称因子也与入射天顶角有关。文中用这种模式计算了太阳短波以及地球红外热辐射通过卷云时的辐射通量传输性质以及方位平均强度的分布。将上述二维模式的计算结果与通常的三维模式(即假定冰粒子在三维空间随机分布)相比较,表明冰晶的优先取向对卷云的反照率有重要影响,两种模式的反照率可以相差8%。另一方面,对于红外辐射而言,两个模式的向上辐射强度有显著的差别,但是冰晶的取向状况对红外辐射通量影响较小。上述结果表明,冰晶的优势取向可能是决定卷云反照率的一个重要因子,同时它对于利用红外辐射探测卷云的组成和结构来说有重要的影响。

A 2-D MHD simulation is performed to study the coupling of tearing mode instability (TM) with Kelvin-Helmholtz instability (K-H) when a B field shear exists at the magnetopause along with the velocity shear. It is found that the Alfvèn Mach number, MA plays an essential role in determining the properties of the coupled instability. In the case of B0 = 1.0, Rm-1 = 2.0 and R-1 = 0.1, if MA < 0.4, the spontaneous TM is dominated in the system. When 0.4 ≤ MA < 1.4, TM is apparently modified by K-H. As MA ≥5 1.4,the...

A 2-D MHD simulation is performed to study the coupling of tearing mode instability (TM) with Kelvin-Helmholtz instability (K-H) when a B field shear exists at the magnetopause along with the velocity shear. It is found that the Alfvèn Mach number, MA plays an essential role in determining the properties of the coupled instability. In the case of B0 = 1.0, Rm-1 = 2.0 and R-1 = 0.1, if MA < 0.4, the spontaneous TM is dominated in the system. When 0.4 ≤ MA < 1.4, TM is apparently modified by K-H. As MA ≥5 1.4,the coupled instability, called the vortex induced tearing mode instability (VITM), appears to be intrinsically different from the conventional TM. The long time asymptotic quasi-static state for VITM is characterized by a large scale fluid vortex together with a co-centred magnetic island.

本文用二维MHD数值模拟研究了地球磁层顶同时存在速度剪切和磁场剪切时Kelvin-Helmholtz不稳定性(K-H)和撕裂模不稳定性(TM)的耦合过程。在雷诺数和磁雷诺数确定时,Alfvèn马赫数值(M_A)对耦合特性起决定性作用。在本文选取的参数条件下,若M_A<0.4,自发TM占主导地位;当0.4≤M_A<1.4时,TM受到K-H明显调制;如果M_A≥1.4,K-H引起的涡旋运动起控制作用,导致一种新的不稳定性产生。该不稳定性称作涡旋撕裂模不稳定性。其饱和后长时间渐近状态由一个大尺度的流体涡旋和同心磁岛组成。在地球磁层顶通量传输事件(FTEs)中它可能起着重要作用。
