Astronomers can observe Giant Molecular Clouds (GMCs) in the Milky Way to learn more about motions of these clouds and the material that composes them. This article describes a study where observations of GMC W 37 were made with the 13.7 m single-dish telescope based at the Delingha station administered by Purple Mountain Observatory. The results of this study can help advance this field of study.
