MeteoInfo 对读取4G左右大小的wrfout文件有问题吗？

aspen

读取一个1G大小的wrfout文件时，变量显示、画图等都没有问题。  
读取一个4G大小的wrfout文件则出问题，不显示变量，也不能画图。
请问可能是什么原因呢？  
多谢。  
数据信息显示如下：
File Name: E:\flexpart\wrfout_d01_2017-09-03-00.nc
File type: null (null)
Dimensions: 0
Global Attributes:
Variations: 0



脚本里报错 ：

从错误信息来看不是文件大小的问题，可能是netCDF生成的有问题。

请问版主，那要怎么解决呢？是WRF数据跑的不对吗？
