龙胜县近50年气候变化特征分析
Climate Change Characteristics of Longsheng County in Recent 50 Years
摘要
Abstract
Basing on the temperature, precipitation and sunlight data in Longsheng County from 1961 to 2010, using the methods of linear regression, polynomial regression, moving average and anomaly, the climate change characteristics of Longsheng County was analyzed. It shows that in the past 50 years, the annual average tempera- ture and annual average minimum temperature have an obvious upward trend. The annual average minimum (max- imum) temperature raises significantly (gently).The interdecadal variations of annual average temperature and av- erage annual minimum temperature is consistent. It has been in a relatively warm period since 1990s.The annual total precipitation is roughly fiat. But the precipitation of spring and summer has a decreasing trend after 2000. The sunshine hours and the temperatures are positive (anti-) phase correlation before 1990s (from the 1990s to first five years of 21st century).关键词
