摘要:

利用石家庄地区5个观测站2008~2010年逐日的草面温度、地面温度和气温观测数据,分析讨论了该地区草面温度平均值、极端值、日较差特征以及草面温度与地面温度、气温在不同气象条件下三者之间的变化关系。结果表明:全地区年平均草面温度呈现出北低南高的特点,西南部山区最高;年平均最高草面温度中部地区最高,年平均最低草面温度西南部山区最高;草面温度日较差的大小和纬度、季节、自然地理条件等因素有关,中部地区日振幅最大;地面温度的极端日振幅最大,气温的极端日振幅最小;在晴天少云状况下草面温度与气温、地面温度呈现明显的正相关;地面有积雪时地面温度与草面温度的年平均绝对差值最大,阴雨天气时草面温度与气温的年平均绝对差值最小。

关键词: 草面温度, 地面温度, 气温, 不同气象条件

Abstract:Based on the daily temperature observation data of 5 stations in Shijiazhuang from 2008 to 2010,the average,extreme values and daily ranges of grass land temperature,as well as relationships between grass land temperature,ground temperature and air temperature under various meteorological conditions were analyzed.The results show that annual average of grass land temperature presented low in the north and high in the south,and highest in the south-west mountainous region.The maximum of annual mean grass land temperature was highest in the central region,the minimum of annual mean grass land temperature was lowest in the southwest mountainous region.The daily range of grass land temperature was affected by latitude,season and geographical conditions,and the diurnal amplitude was biggest in the central region.The diurnal amplitude of ground temperature was maximum,but minimum for air temperature.There was a positive correlation between grass land temperature and air temperature,ground temperature in a little cloudy days.The absolute difference of annual average value between ground temperature and grass land temperature was maximum when ground was covered with snow,but minimum in rainy days.

Key words: ground temperature, air temperature, Shijiazhuang, grass land temperature
