However, the origin of these clouds in the Milky Way's wind is unclear. This paper presents new high-resolution MeerKAT observations of three atomic gas clouds and studies the relationship between the atomic and molecular phases at $\\sim 1$ pc scales. The clouds' atomic hydrogen column densities, $N_{\\mathrm{HI}}$, are less than a $\\mbox{few}\\times 10^{20}$ cm$^{-2}$, but the two clouds closest to the Galactic Centre nonetheless have detectable CO emission.
