| 摘 要： | 利用Delaunay三角网对目标区域进行剖分,在对地表温度进行高度插值后,运用二重积分的思想建立了基于Delaunayr三角剖分的地表平均温度测量模型.同时以南极地表平均温度的测量为例,将67个自动气象地表台站、46个气象地表台站以及56个高空气象观测站的加权平均温度与地表平均温度的数据进行分析,得到南极2015全年地表平均温度均在-8℃以下,最低温约为-20℃,符合南极大陆地表温度的实际情况.

| Abstract: | We use Delaunay triangulation on the target region partition.After height interpolation on the surface temperature,we establish the surface average temperature measurement model based on the idea of double integral and Delaunay triangulation.At the same time,take the measurement of the surface average temperature in Antarctic as an example,we analyze the weighted average temperature and average surface temperature of 26 Upper air stations,67 surface aws stations,and 46 surface stations,and we draw a conclusion that the annual average surface temperature in Antarctic in 2015 is below-8 ℃,the lowest temperature is about-20 ℃,which are in accordance with the actual situation of the surface temperature in Antarctic. |
