The synoptic map of the solar wind speed (SWS) estimated by the computer-assisted tomography (CAT) method with interlanetary scintillation observations is constructed for the 1909 Carrington rotation. A similar synoptic map of expansion rate (RBR) of the coronal magnetic field calculated by the so-called 'potential model' with the photospheric magnetic field is also constructed under the radial field assumption (RF model). These maps consist of 64 800 (180×360) data points of equal area. We examine for the first time relations between the SWS estimated by the CAT technique and the RBR calculated by the RF model. A highly significant correlation is found between the SWS and the RBR. A simple correlation coefficient is about-0.72 ; that is, high-velocity winds emanate from photospheric areas corresponding to a low expansion rate of the coronal magnetic field, and low-velocity. winds emanate from photospheric areas of high expansion rate. This result suggests that there is some acceleration mechanism relating to the coronal field expansion.

利用行星际闪烁观测资料，利用计算机辅助层析成像（CAT）方法，构造了1909年卡林顿自转的太阳风速度（SWS）天气图。在径向场假设（RF模型）下，利用光球磁场和所谓的“势模型”计算了日冕磁场的膨胀率（RBR），并构造了类似的天气图。这些地图由64 800个（180×360）等面积数据点组成。我们研究的第一次之间的关系SWS估计的CAT技术和RBR计算的RF模型。一个高度显着的相关性之间的SWS和RBR。一个简单的相关系数约为-0.72;也就是说，高速风来自对应于日冕磁场低膨胀率的光球区，而低速风来自日冕磁场低膨胀率的光球区。风来自膨胀率高的光球区。这一结果表明，存在着某种与日冕场膨胀有关的加速机制。
