| 摘 要： | 对长沙市2011、2012年夏季(6—9月)百叶箱内外温度同步观测资料进行统计分析,结果表明:百叶箱内外温度呈现白天箱外温度高于箱内,晚上低于箱内的日变化特征,但不同类型天气交替时间存在早晚不一。箱内外夏季平均温度、极端最高温度的变化趋势一致,但箱外温度高于箱内,且不同类型天气百叶箱内外温度存在差异,阴雨天平均相差1.2℃,多云差2.8℃,晴天差3.1℃,极端最高温差达6.4℃。特别是日最高温度大于等于35℃的高温日数,2年箱内共出现61天,而箱外多达125天;箱内极端最高温度为38.9℃,而箱外极端最高温度高达42.0℃。因此,在高温预报和公共气象服务工作中,应当要考虑外界温度(百叶箱外温度)与百叶箱内温度之间存在的差异。

| Abstract: | A statistical analysis is carried out on the simultaneous observation data of the temperature inside and outside the thermometer shelter in Changsha during summer in 2011 and 2012. The results show that the temperature outside the thermometer shelter is higher （lower） than that inside the thermometer shelter in the daytime （nighttime）. However, there exists a similar variation trend for average temperature and extreme maximum temperature inside and outside the thermometer shelter. The average temperature and extreme maximum temperature outside the thermometer shelter is higher than that inside the thermometer shelter. Furthermore, there exists difference between temperature inside and outside the thermometer sheiter during different weather conditions, with an average difference of 1.2 ℃ in rainy days, 2.8 ℃ in sunny days, and 3.1 ℃ cloudy days. The difference of extreme maximum temperature inside and outside the thermometer shelters is up to 6.4 ℃. Especially, the number of days with the extreme maximum temperature inside the thermometer shelter higher than 35 ℃ is 61 days in two year, and that inside the thermometer shelter up to 125 days. The extreme maximum temperature inside and outside the thermometer shelter is 38.9 ℃ and 42.0℃respectively. Therefore, the difference between temperature inside and outside the thermometer shelter should be taken into account in high temperature forecast and public meteorological service. |
