摘　　要：在当前大数据、人工智能的时代,人类对大气的探测手段越来越多,每天获取的数据也在呈爆炸式增长。随着科学计算可视化技术的不断发展,凭借计算机强大的数据处理能力,人们对于海量数据处理的方式也越来越多。该文首先利用MATLAB绘制气象流线切片图,然后基于Panoply软件对NetCDF格式的气象数据进行可视化操作,分别制作气温变化的一维和二维分布图以及风场变化的联合分布图,最后实现东南亚地区某个时间段的地表平均风场变化的可视化。In the era of big data and artificial intelligence,there are more and more human detection methods for the atmosphere,and the data obtained every day is also increasing explosively.With the continuous development of scientific computing visualization technology,using the powerful ability of data processing of computers,people have more and more ways to deal with massive data.In this paper,firstly,the meteorological streamline slice map is drawn by MATLAB,and then the meteorological data in NetCDF format are visualized based on Panoply software,and the one-dimensional and two-dimensional distribution maps of temperature change and the joint distribution map of wind field change are made respectively.Finally,the visualization of the change of surface mean wind field in Southeast Asia is realized.
