1952-2012年蚌埠市雷暴气候统计特征研究

利用蚌埠市1952-2012年雷暴资料,采用气候倾向率、保证率、Mann-Kendall突变检验和Morlet小波分析等气候诊断方法,分析蚌埠市近61a雷暴的气候变化趋势、初终日分布、突变和周期变化特征.结果表明:蚌埠市雷暴日数年际变化较大,平均雷暴日数总体呈略下降趋势,夏季雷暴日数下降趋势最明显;雷暴有很强的季节性,集中出现在4-9月份,以7月份出现最多;雷暴初日普遍在3月中旬,终日普遍在9月下旬,雷暴初终日年际间差异大;雷暴日数呈先升后降的气候变化趋势,显著突变年份是1980年;雷暴日数年际和年代际变化存在2-4a、10-12a以及准16a振荡周期.

Climatotherapy

For successful climatotherapeutic treatment the body has to be exposed daily over several weeks under an exact dosage regime, to the biometerological conditions. For doing this — to provide rest, or to apply stimuli — four different methods are described: climatic terrain treatment, fresh air rest-cures, air baths and heliotherapy. Climatotherapy is conducted in a marine climate, in upland and in alpine regions. These three zones differ in the intensity of their climatic stimuli. Today, climatotherapy has become more differentiated, and has been newly structured following objective parameters. It always refers to specific diseases.

Response of water budget to recent climatic changes in the source region of the Yellow River

Discharge in the source region of the Yellow River significantly declined after 1990.China Meteorological Administration(CMA) data show that precipitation in this region was low in the 1990s but returned to above normal after 2002;in recent decades there has been rapid warming of surface air,moistening and wind speed decrease.To investigate the influences of recent climatic changes on the water budget,this study simulates the surface water budget at CMA stations within and surrounding the source region during 1960-2006,using an improved land surface model.Results indicate that the spatial pattern of precipitation change is an important factor(except for precipitation amount and intensity) in determining the response of runoff to precipitation changes.Low runoff in the 1990s was consistent with precipitation amount and intensity.The recovery of precipitation after 2002 is mainly from increased precipitation in the dry area of the source region.Evaporation was mainly limited by water availability in this dry area,and thus most of the precipitation increase was evaporated.By contrast,energy availability was a more important influence on evaporation in the wet area.There was more evaporation in the wet area because of rapid warming,although precipitation amount partly decreased and partly increased,contributing to the reduction of runoff after 2002.This control on evaporation and its response,together with the modified spatial pattern of precipitation,produced a water budget unfavorable for runoff generation in the source region during recent years.
