基于舒适度的广东省茂名市避寒气候资源分析

An Analysis of Winter Comfortable Climate Resources in Maoming City of Guangdong Based on Climatic Comfortability

基于1991—2020年中国地面气候平均值资料,利用气候舒适度计算方法,分析了广东省茂名市避寒气候资源和我国的主要避寒需求。结果表明:茂名地区冬季气温、相对湿度和日照时数适宜,气候舒适期长,避寒气候资源优势明显。建议充分利用气候资源特色,打造茂名避寒旅游地。在全球变暖的背景下,茂名近30年冬季(12月—翌年2月)气温下降,气候舒适天数略减少,避寒气候资源呈现减少趋势,冬季强降温和寒潮在增多,但气候变化对茂名开展避寒旅游影响不大。

With the climatic comfortability method,the climatological normals of 1991–2020 were used to analyze the climate resources of Maoming City,a winter resort in Guangdong Province.The results show that Maoming is featured with winter comfortable resources,including the proper winter temperature,relative humidity and sunshine duration.Meanwhile,it also has a long period of comfortable winter.It is suggested to make full use of the advantage of climate resources to make Maoming a winter resort.Under the background of global warming,the winter temperature of Maoming(December to February)has decreased in the past 30 years,accompanied with slight decrease of the number of climate comfort days.In addition,winter comfortable resources in Maoming have also shown a declining trend,with increased weather events of strong temperature drop and cold wave.Even so,the development of winter tourism in Maoming will not be greatly affected by the global climate change.
