Study on Cloud Change Trend under the Influences of Climate Warming
[Objective] The research aimed to study influences of the climate warming on cloudage and cloud-like structure in south area. [Method] Annual average temperaturet total cloudage and low cloudage in Caiman, Nankang, Shangyou and Xinfeng of Gannan area from 2004 to 2011 were selected. Influences of the annual average temperature change on annual average total cloudage, annual average low cloudage and cloud-like structure in Gannan area were analyzed. [Result] Climate warming is affecting cloudage and cloud-like structure in south area. When annual average temperature rose, annual average total cloudage and low cloudage both presented decrease trends. When annual average temperature declined, annual average total cloudage and low cloudage both presented rise trends. When annual average temperature was equal to that in previous year at low level, annual average total cloudage and low cloudage increased. Annual average low cloudage was different in mountain area and basin. Influence of the annual average temperature on annual average total cloudage and low cloudage in basin area at low altitude presented slow fluctuation form, and had severe influence on that in mountain area at high altitude. Rise of the annual average temperature had larger influence on high cloudage. Declining of the annual average temperature had larger influence on annual average low cloudage. Under different weather situations, formation and disappearance change of the km cloud had different manifestation forms. [Conclusion] Tlie research provided scientific basis for studying changes of the cloudage and cloud-like structure in South China as climate wanning.
