【摘要】 根据赣州2003～2004年紫外线辐射观测资料,统计分析10～13时平均紫外线辐射量(zwx)与本站地面气象要素的幂数的关系变化,(结果表明:紫外线辐射量与14时温度(t14)、气压(p14)、湿度(e14)都有较好的相关关系,其中与t14、e14正相关,与p14负相关;分析zwx与t14x,e14x,p14x,的幂次变化关系,表明x在区间[0.1,3.0]变化时,正负相关维持不变,zwx与t142.4的相关系数达0.82。)根据分析结果建立了当地紫外线辐射强度指数预报方程,(预报评分分析表明该预报方程有较强的可用性,)在预报业务中具有实际参考价值。更多还原

【Abstract】 According to 2003-2004’s ultraviolet ray radiation observed data from Ganzhou local meteorological station,we had statistical analysis on the relational change between the 10～13’h average ultraviolet ray radiation quantity(zwx) and the power change of the Surface meteorological element.(it indicated that the better correlational dependence for the ultraviolet ray radiation quantity with 14 o′clock temperatures(t14),the barometric pressure(p14),and the humidity(e14).and positive correlation with t14、e14,negative correlation with p14;Analyzing the correlation change between zwx and the power change of t14x、e14x、p14x,it was indicated that the positive and negative correlation maintenance is invariable when x changes on the sector [0.1,3.0],the correlation between zwx and t14(2.5) is amounts to 0.82.) According to the result we established the local ultraviolet ray radiation intensity index prognostic equation,)(this prognostic equation had a stronger usability,) it had the actual reference value in the forecast service.更多还原
