摘　　要：为了有效显示小区域气象观测要素分布,文章分析了显示气象观测要素的各种方法,指出了离散显示、连续显示的特点,在不同幂指数下,利用反距离加权内插法对南京信息工程大学西苑老食堂及周边区域的气温、湿度、气压进行了处理,在同一时间下,与普通克里金内插法进行了比较,结果表明反距离加权内插法优于普通克里金内插法,更适合准确、清晰地显示小区域的气温、湿度和气压气象要素的分布。In order to effectively display the distribution of meteorological observation elements in a small area,this paper analyzes various methods of meteorological observation elements display,and points out the characteristics of discrete display and continuous display.Under different power exponents,the temperature,humidity and air pressure of Xiyuan old canteen and its surrounding area of Nanjing University of Information Science and Technology were processed by inverse distance weighted interpolation method.At the same time,compared with the ordinary Kriging interpolation method,the results show that the inverse distance weighted interpolation method is better than the ordinary Kriging interpolation method,which is more suitable for accurately and clearly displaying the distribution of temperature,humidity and pressure meteorological elements in small areas.
