How to Analyze Results
-----------------------
Navigate to ``halloweenHRRR/2019103012/postprd`` or ``halloweenRAP/2019203012/postprd``. This directory contains the post-processed data generated by the :term:`UPP` from the ``halloween`` forecast. After the ``plot_allvars`` task completes, this directory will contain ``.png`` images for several forecast variables.

Copy ``.png`` Files onto Local System
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Users who are working on the cloud or on an HPC cluster may want to copy the ``.png`` files onto their local system to view in their preferred image viewer. Detailed instructions are available in the :ref:`Introduction to SSH & Data Transfer <SSHDataTransfer>`.

In summary, users can run the ``scp`` command in a new terminal/command prompt window to securely copy files from a remote system to their local system if an SSH tunnel is already established between the local system and the remote system. Users can adjust one of the following commands for their system:

.. code-block:: console
scp username@your-IP-address:/path/to/source_file_or_directory /path/to/destination_file_or_directory
# OR
scp -P 12345 username@localhost:/path/to/source_file_or_directory /path/to/destination_file_or_directory
Users would need to modify ``username``, ``your-IP-address``, ``-P 12345``, and the file paths to reflect their systems' information. See the :ref:`Introduction to SSH & Data Transfer <SSHDataTransfer>` for example commands.


Experiment 3: Examining Forecast Plots at Peak Intensity
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In this experiment will be looking at plots from HRRR and RAP input files while the Halloween Storm is at or approaching peak intensity.

Analysis
^^^^^^^^^^^

.. _fcst4_250wind:

250mb Wind
``````````
Any good forecast starts with analyzing a 250mb wind chart. Using a 250mb wind plot, users will be able to point out key features such as jet placement, jet maxes, troughs, ridges and more. Analyzing this also allows us to see where the potential for the strongest severe weather is.

In the 250mb Wind plots, the ``halloweenHRRR`` and ``halloweenRAP`` plots are nearly identical at forecast hour f036. This shows great model agreement. Analyzing this chart we can see multiple ingredients signaling a significant severe weather event over eastern CONUS. The first thing to notice is the placement of the jet streak along with troughing approaching the eastern US. Also notice an extreme 150KT jet max over southern Ohio further fueling severe weather. The last thing to notice is the divegence aloft present over Eastern Conus, seeing divergence present all the way up to 250mb indicates a strong system.
