摘要

A statistical analysis on the simultaneous observation data of the temperature inside and outside the themometer shelter in Changsha during summer of 2011 and 2012 was carried out. The results show that the temperature outside the themometer shelter is higher( lower) than that inside the themometer shelter in the daytime( nighttime). However,there exists a similar variation trend for the average temperature and the extremely maximum temperature inside and outside the themometer shelter in summer. The average temperature and the extremely maximum temperature outside the themometer shelter are higher than that inside the themometer shelter. Furthermore,there exists a difference between the temperatures inside and outside the themometer shelter during different weather conditions. The difference of average temperature reaches 1. 2 ℃ in rainy day,2. 8 ℃ in cloudy day and 3. 1 ℃ in sunny day,and the extremely maximum temperature difference reaches 6. 4 ℃. Especially for the days of high temperature ≥35 ℃,there is 61 high temperature days inside the themometer shelter,while there is 125 high temperature days inside the themometer shelter during 2011- 2012. Furthermore,the extremely maximum temperatures inside and outside the themometer shelter are 38. 9 and42. 0 ℃ respectively. Rainfall and showery rain are the most effective ways to relieve the high temperature in summer. Therefore,the difference between the temperatures inside and outside the themometer shelter should be taken into account in the high temperature forecast and public meteorological service.
