Forecast Model Vertical Sounding
|
||||
================================
|
||||
`Notebook <http://nbviewer.ipython.org/github/Unidata/python-awips/blob/master/examples/notebooks/Forecast_Model_Vertical_Sounding.ipynb>`_
|
||||
The ModelSounding class allows us to create a vertical sounding through
|
||||
any available AWIPS model with isobaric levels.
|
||||
Python-AWIPS Tutorial Notebook
|
||||
|
||||
- A Shapely Point geometry is used to select longitude and latitude:
|
||||
from shapely.geometry import Point point = Point(-104.67,39.87)
|
||||
--------------
|
||||
|
||||
- Parameters ``['T','DpT','uW','vW']`` are requested for all isobaric
|
||||
levels available for the selected model.
|
||||
Objectives
|
||||
==========
|
||||
|
||||
- There is a single-record query performed for ``level = "0.0FHAG"`` to
|
||||
determine the surface pressure level.
|
||||
- Use python-awips to connect to an edex server
|
||||
- Request data using the `ModelSounding
|
||||
class <http://unidata.github.io/python-awips/api/ModelSounding.html>`__
|
||||
in addition to using the normal `DataAccess
|
||||
class <http://unidata.github.io/python-awips/api/DataAccessLayer.html>`__
|
||||
- Create and compare vertical sounding from different AWIPS model data
|
||||
with isobaric levels
|
||||
- Use `Shapely Point
|
||||
geometry <https://shapely.readthedocs.io/en/stable/reference/shapely.Point.html>`__
|
||||
to define a point
|
||||
- Convert between units when necessary
|
||||
- Use MetPy to create
|
||||
`SkewT <https://unidata.github.io/MetPy/latest/api/generated/metpy.plots.SkewT.html>`__
|
||||
and
|
||||
`Hodograph <https://unidata.github.io/MetPy/latest/api/generated/metpy.plots.Hodograph.html>`__
|
||||
plots
|
||||
|
||||
- Pay attention to units when switching models. This notebook was
|
||||
written for the NAM 40km AWIPS model where temperature and dewpoint
|
||||
are returned as Kelvin and wind components as m/s.

1 Imports
|

---------
|
||||
|
||||
The imports below are used throughout the notebook. Note the first
|
||||
import is coming directly from python-awips and allows us to connect to
|
||||
an EDEX server. The subsequent imports are for data manipulation and
|
||||
visualization.

2 EDEX Connection
|

-----------------
|

|

First we establish a connection to Unidata’s public EDEX server. This
|

sets the proper server on the **DataAccessLayer**, which we will use
|
||||
numerous times throughout the notebook.

3 Define Useful Variables

The plotting in this notebook needs a model name, a location point

the initial forecast run.

This function is used to get the initial forecast model data for surface

determine the surface pressure. It uses the

`ModelSounding <http://unidata.github.io/python-awips/api/ModelSounding.html>`__

and returns arrays for pressure, temperature, dewpoint, and the u and v

Since we’re plotting many different models for comparison, all that code

||||
was used to create this function.
|
||||
|
||||
The function takes the model name, reference time, and the pressure,
|
||||
temperature, dewpoint, u-component, v-component, and wind arrays. It
|
||||
plots a skewT and hodograph using metpy.

7 Retrieve Necessary Plotting Data
|
||||
----------------------------------
|
||||
|
||||
First we get the initial data at surface level using the
|
||||
get_surface_data function, and then pass those initial data arrays onto
|
||||
the get_levels_data request to finish populating for additional heights
|
||||
needed for Skew-T plots. We want to keep track of the pressure,
|
||||
temeperature, dewpoint, u-component, v-component, and wind arrays so we
|
||||
store them in variables to use later on.
|
||||
|
||||
.. code:: ipython3
|
||||
|
||||
p,t,d,u,v = get_surface_data(model,point,timeRange)
|
||||
|
||||
p,t,d,u,v,w = get_levels_data(model,point,timeRange,p,t,d,u,v)

|

Here we use our plot_skewT function to generate our skewT & hodograph
|
||||
charts for the data we retreived so far. This is where the pressure,
|
||||
temperature, dewpoint, and wind data is needed.

||||

9 Model Sounding Comparison
|
||||
---------------------------
|
||||
|
||||
Now that we know how to retreive and plot the data for one model, we can
|
||||
run a loop to retreive data for various models and plot them for
|
||||
comparison. In this example we’ll also plot RAP13 and GFS20 data to
|
||||
compare with NAM40.
|
||||
|
||||
This is also where our functions become so important, because we can
|
||||
easily recall all that logic and keep this for-loop fairly simple.
|
||||
|
||||
.. code:: ipython3
|
||||
|
||||
models = ["RAP13", "GFS20", "NAM40"]
|
||||
parms = ['T','DpT','uW','vW']
|
||||
|
||||
for modelName in models:
|
||||
timeReq = DataAccessLayer.newDataRequest("grid")
|
||||
timeReq.setLocationNames(modelName)
|
||||
cycles = DataAccessLayer.getAvailableTimes(timeReq, True)
|
||||
times = DataAccessLayer.getAvailableTimes(timeReq)
|
||||
fcstRun = DataAccessLayer.getForecastRun(cycles[-1], times)

<p>This function is similar to <em>get_surface_data()</em>, except it gets data
|

values for presure heights above the surface. It uses the

<a class="reference external" href="http://unidata.github.io/python-awips/api/ModelSounding.html">ModelSounding</a>
|

data object from python-awips to retrieve all the relevant information.</p>
|

<p>It takes the model name, location, and time (similar to the other
|
||||
function), and also takes the instantiated pressure, temperature,
|
||||
dewpoint, and wind vector arrays.</p>
|
||||
<p>It returns the fully populated pressure, temperature, dewpoint,

u-component, v-component, and computed wind arrays.</p>

|

<p>Since we’re plotting many different models for comparison, all that code
|
||||
was used to create this function.</p>
|
||||
<p>The function takes the model name, reference time, and the pressure,
|
||||
temperature, dewpoint, u-component, v-component, and wind arrays. It
|
||||
plots a skewT and hodograph using metpy.</p>

<p>First we get the initial data at surface level using the
|
||||
get_surface_data function, and then pass those initial data arrays onto
|
||||
the get_levels_data request to finish populating for additional heights
|
||||
needed for Skew-T plots. We want to keep track of the pressure,
|
||||
temeperature, dewpoint, u-component, v-component, and wind arrays so we
|
||||
store them in variables to use later on.</p>

<h3>9 Model Sounding Comparison<a class="headerlink" href="#model-sounding-comparison" title="Permalink to this heading"></a></h3>
|
||||
<p>Now that we know how to retreive and plot the data for one model, we can
|
||||
run a loop to retreive data for various models and plot them for
|
||||
comparison. In this example we’ll also plot RAP13 and GFS20 data to
|
||||
compare with NAM40.</p>
|
||||
<p>This is also where our functions become so important, because we can
|
||||
easily recall all that logic and keep this for-loop fairly simple.</p>
