天气现象符号分布图实际就是散点图,可以用scatterm函数绘制,但之前需要创建天气符号图例,用weatherspec函数。如果只需要绘制某些天气现象(比如雾、霾),可以给出相应的天气符号序号列表(可以在网上查找)。
脚本程序:
#Set data folders basedir = ‘D:/MyProgram/Distribution/java/MeteoInfo/MeteoInfo‘ datadir = os.path.join(basedir, ‘sample/MICAPS‘) mapdir = os.path.join(basedir, ‘map‘) #Read shape files lworld = shaperead(os.path.join(mapdir, ‘country1.shp‘)) lchina = shaperead(os.path.join(mapdir, ‘bou2_4p.shp‘)) #Read station data f = addfile_micaps(os.path.join(datadir, ‘10101414.000‘)) data = f.stationdata(‘WeatherNow‘) #Plot axesm(bgcolor=(204,255,255)) geoshow(lworld, edgecolor=‘k‘, facecolor=(255,251,195)) geoshow(lchina, edgecolor=‘k‘) ls = weatherspec() layer = scatterm(data, symbolspec=ls) #colorbar(layer) xlim(72, 136) ylim(16, 55)
