The Monte Carlo simulation is employed to study the distribution of superbubbles and supernova remnants according to the chimney model of the interstellar medium, taking into account the global spiral pattern in the Galaxy. The observabilities of superbubbles and hot gas within them by H I 21-cm and diffuse X-ray emission are examined, showing expected observational characteristics of H I supershells and an X-ray ridge. The structure of interstellar medium with many superbubbles concentrated in spiral arms, the so-called chimney model, does offer a possible explanation to the various observed structures of the interstellar medium. 20 refs.
