云南冰雹灾害气候特征及其变化
Climatic Characteristics and Changes of Hail Disasters in Yunnan
摘要
Abstract
Using hail observed daily data from 125 meteorological stations during 1960-2015, GDP and meteorological disaster data of Yunnan Province during 2005-2015, Climatic characteristics and changes of hail disasters in Yunnan are analyzed with various statistical methods.Results show that, hail events can be found in the whole year in the whole territory of Yunnan.There are obvious different spatial-temporal distributions for hail events in Yunnan.East, South, West and northwest of Yunnan have more hail events than others region.Main hail period of Northwest Yunnan, high altitude region, is in April-October.Main hail period of other areas is in the spring, February-April.Hail event of Yunnan has obvious interannual and interdecadal variations.And there is a significant reduction trend.2001 is the mutation point of change.There is a significant 2-4 years oscillation period in1960s and 1975-1999.In 20 Century, the change characteristics of hail events are positive anomaly and wide oscillation.In 21 Century, the characteristics is conversely.With the economic development, the loss of hail disaster in Yunnan has increased year by year.But the ratio of the disaster loss and GDP of Yunnan province has decreased year by year.Weather modification for hail is one of the main influencing factors.关键词
