The physical parameters of the solar wind observedin-situnear 1 AU have been studied for several decades, and relationships between them, such as the positive correlation between the solar wind plasma temperature,, and velocity,, and the negative correlation between density,, and velocity,, are well known. However, the magnetic field intensity,, does not appear to be well correlated with any individual plasma parameter. In this article, we discuss previously under-reported correlations betweenand the combined plasma parametersas well as betweenand. These two correlations are strong during periods of corotating interaction regions and high-speed streams, and moderate during intervals of slow solar wind. The results indicate that the magnetic pressure in the solar wind is well correlated both with the plasma dynamic pressure and the thermal pressure.
