Abstract

Climate change has emerged as a global environmental issue, and the IPCC said that global warming is a kind of foregone conclusion (2007, IPCC). Global warming in Korea is going on at a higher level than the average level of the entire world due to dazzling industrial development. This research conducted a statistic analysis of climate change in Honam region. The materials used for this research are the average temperature, maximum temperature, minimum temperature, precipitation, humidity, and sunshine duration in Honam inlands (Gwangju, Suncheon) and coastal areas (Mokpo, Haenam) for the past 37 years (1973~2009). The analysis method was to statistically interpret the secular change of each element and the change of rain factor and season, and then they were compared with the reports by IPCC and those of other regions in Korea and finally analyzed. As a result, it was found that the annual average temperature in Honam region was 13.4℃, and that its change was +2.2℃/100 year. The annual average maximum temperature was 18.9℃ and its change was +2.7℃/100 year. The annual average minimum temperature was 8.9℃, and its change was +1.4℃/100 year. The annual average precipitation was 1338.9mm, and its change was +325.4mm/100 year. The annual average humidity was 72.5%, and its change was 19.3%/100 year. The annual average sunshine duration was 2180.5 hours, and its change was -720.7 hour/100 year. The average of average rain factor was 99.9, and its change was 7.1/100 year. When it comes to season change, the tendencies show up that summer generally begins earlier, summer becomes longer, and autumn and winter get shorter and shorter. The comparison of inlands and coastal areas showed that the change in inlands was larger than that of coastal areas. The result implies that inlands are more rapidly changing into the tropical monsoon climate region from the humid climate region than coastal areas. Therefore, positive responding strategies need to be established in order to resolve the issues of climate and water resources taking place along with increased temperature and simultaneously cope with changes in agricultural and fishery species arising from vegetation variation.
