语真反映yum安装的NCL画图会出现莫名其妙的问题，再加上历史遗留的load问题，索性干脆按照官网指导，用conda重新安一个NCL和专门给它独享的环境。

##### Re-Install NCL through conda (XW: Feb 22, 2020)
follow this page: http://www.ncl.ucar.edu/Download/conda.shtml
run this command to install NCL 6.6.2 into an environment named "NCL6"
conda create -n NCL6 -c conda-forge ncl

Please note that everyone, for everytime,
should run "conda activate NCL6" right before using NCL.

"conda deactivate" or not doesn't matter.

机器时区默认是错的，故手工修改一下时区信息

##### Reset Timezone
timedatectl set-timezone Asia/Shanghai
timedatectl (this command will show below outputs)
(base) root@cs:~# timedatectl

##### Python3 w/ Anaconda
Download Anaconda3-2019.10-Linux-x86_64.sh from tuna.tsinghua and install it
After installation, it is shown:
-----
installation finished.
Do you wish the installer to initialize Anaconda3
by running conda init? [yes|no]
[no] >>> yes
no change     /opt/anaconda3/condabin/conda

==> For changes to take effect, close and re-open your current shell. <==

If you'd prefer that conda's base environment not be activated on startup,
   set the auto_activate_base parameter to false:

conda config --set auto_activate_base false

Thank you for installing Anaconda3!
