Abstract

Abstract: Based on the daily surface meteorological observation data from 1980 to 2014 and the cases of residents' heatstroke during June to August from 2011 to 2014 in Ningbo,a new meteorological grade of heatstroke was established using a quantile method according to the correlation between local meteorological factors and heatstroke cases.The 45th,70th and 85th quantiles were used to divide the maximum temperatures and heat indices into new division grades.The meteorological grades of heatstroke were improved by combining the heatstroke cases and the persistent days of the maximum temperature.The meteorological grades of heatstroke were classified as possible,easy,easier and extremely easy occurence.The results show that the improved meteorological grade of heatstroke is more suitable to Ningbo region.The heatstroke grade determined by the meteorological conditions and heatstroke cases are able to reflect the risk of heatstroke.This work provides a reference for predicting the real meteorological grades of heatstroke.

Key words: Heatstroke, Heat index, Persistent time of high temperature, Quantile method, Meteorological grade
