A chinook wall cloud is a specific type of cloud formation that occurs over the Rocky Mountains and signals the approach of a chinook wind. It is characterized by a long, horizontal cloud bank that appears to be attached to the mountaintops. This cloud formation is caused by warm, moist air rising up the windward slopes of the mountains and cooling as it reaches higher altitudes, leading to the formation of clouds. As the air continues to rise and cool, it can eventually reach the point of saturation and begin to rain or snow, causing the chinook to dissipate. Therefore, choice A best defines the features of a chinook wall cloud.
