Continental tropical (cT) air masses originate over land in warm regions, typically in the summer months. They are characterized by high temperatures and low humidity, resulting in dry and hot conditions. These air masses can influence weather patterns, especially in areas like the southwestern United States and northern Mexico. When a continental tropical air mass moves into a region, it can lead to clear skies and increased temperatures. However, it may also contribute to drought conditions if it persists for an extended period. Understanding cT air masses is essential for meteorologists when predicting weather changes and patterns.
