Install wrf intel.sh

Note:

• The commands in the box below has to be stored in file called install_wrf_intel.sh.
• To execute the script please set the execution permissions by chmod 755 install_wrf_intel.sh.
• usage is install_wrf_intel.sh WRF_RELEASE DIR_TO_TAR_GZ_FILES
• The final installation of WRF and WPS will be in the directories WRFV3_v${WRF_RELEASE}_intel and WPS_v${WRF_RELEASE]_intel, respectively
• The orginal folders WRFV3 and WPS will be removed during the installation process!
