中文摘要: 为了更好开展高温中暑气象预报服务和气候评价工作,以武汉市2003—2005年高温期间逐日 中暑人数与当天、前期共33个气象因子为基础资料,通过相关普查寻找关键气象因子,通过 逐步回归方法建立了改进的中暑气象模型,修订了1990年代研制的中暑指数5级划分 标准,新提出了中暑天数的推算方法,并进行了回代检验和2006—2007年试报检验。结果表 明:中暑人数与当日各项气温、气压、日照时数为正相关,与总云量、相对湿度为负相关, 其中气温最为关键,考虑前期气温累积效应后相关系数有所提高;日最高气温≥36℃的累积 高温为首选因子,比1990年代的临界指标上升1℃;建立了3套预报(评估)模型,并推荐使 用以日最高气温≥36℃的累积高温、日平均气温为因子的模型;回代试验、试验报检验表明 ,改进的模型、等级划分标准科学适用。
Abstract:In order to deeply develop the meteorological prediction and climate impact asse ssment of heatstroke by heat wave, the daily heat stroke cases and meteorologi cal factors from 2003 to 2005 in Wuhan are used to choose the key factors by cor relative method. Three regressive models are set up with progressive regr ession on the basis of calculating the single-correlation coefficient of daily h eat stroke numbers and 33 meteorological factors, and the more reasonable grade standards than original model of 1990's are also built up, and a method to calcu l ate days with heatstroke event is designed. The results show that the factors co ncerned temperature are the most important, and the accumulated temperature ≥35 ℃ is selected at first. By experimental test, the results show that the forecas ting value and the real value are relatively identical.
