Climate, Humid Subtropical

Humid subtropical climates are located in the lower mid-latitude regions of the northern and southern hemispheres. These climates typically have long humid summers and short, relatively mild winters. During the summer, humid subtropical climates are influenced by neighboring tropical zones and warm oceans. In humid subtropical climate zones, the subtropical jet stream is present in the summer, often bringing abundant moisture and thunderstorms. During the winter, humid subtropical climates are influenced by weather systems originating in tropical or continental climate zones. Occasionally, weather systems from subarctic regions can penetrate into subtropical regions, bringing severe cold lasting 2–3 days. The mid-latitude jet stream frequently moves over humid–subtropical climate regions in the winter, bringing mid-latitude storms and highly variable day-to-day weather.
