Thunderstorm Detection and Tracking - T-DaTing#

This example shows how to use the thunderstorm DaTing module. The example is based on MeteoSwiss radar data and uses the Cartesian composite of maximum reflectivity on a 1 km grid. All default values are tuned to this grid, but can be modified. The first section demonstrates thunderstorm cell detection and how to plot contours. The second section demonstrates detection and tracking in combination, as well as how to plot the resulting tracks. This module was implemented following the procedures used in the TRT Thunderstorms Radar Tracking algorithm ([HMG+04]) used operationally at MeteoSwiss. Modifications include advecting the identified thunderstorms with the optical flow obtained from pysteps, as well as additional options in the thresholding. A detailed description is published in Appendix A of [FGGB21].

Read the radar input images#

A series of 20 files containing Swiss Cartesian gridded rain rates are imported. Since the algorithm is tuned to Swiss max-reflectivity data, the rain rates are transformed to reflectivity fields using the ‘to_reflectivity’ utility in pysteps.utils.

# Select the input data
date = datetime.strptime("201607112100", "%Y%m%d%H%M")

Example of thunderstorm identification in a single timestep#

The function tstorm_detect.detection requires a 2-D input image, all further inputs are optional.

input_image = Z[2, :, :].copy()
time = timelist[2]
cells_id, labels = tstorm_detect.detection(input_image, time=time)

Properties of one of the identified cells:

Example of thunderstorm tracking over a timeseries#

The tstorm-dating function requires the entire pre-loaded time series. The first two timesteps are required to initialize the flow prediction and are not used to compute tracks.

track_list, cell_list, label_list = tstorm_dating.dating(
    input_video=Z, timelist=timelist
)

You are setting values through chained assignment. Currently this works in certain cases, but when using Copy-on-Write (which will become the default behaviour in pandas 3.0) this will never work to update the original DataFrame or Series, because the intermediate object on which we are setting values will behave as a copy.
A typical example is when you are setting values in a column of a DataFrame, like:

df["col"][row_indexer] = value

Use `df.loc[row_indexer, "col"] = values` instead, to perform the assignment in a single step and ensure this keeps updating the original `df`.

You are setting values through chained assignment. Currently this works in certain cases, but when using Copy-on-Write (which will become the default behaviour in pandas 3.0) this will never work to update the original DataFrame or Series, because the intermediate object on which we are setting values will behave as a copy.
A typical example is when you are setting values in a column of a DataFrame, like:

df["col"][row_indexer] = value

Use `df.loc[row_indexer, "col"] = values` instead, to perform the assignment in a single step and ensure this keeps updating the original `df`.

You are setting values through chained assignment. Currently this works in certain cases, but when using Copy-on-Write (which will become the default behaviour in pandas 3.0) this will never work to update the original DataFrame or Series, because the intermediate object on which we are setting values will behave as a copy.
A typical example is when you are setting values in a column of a DataFrame, like:

df["col"][row_indexer] = value

Use `df.loc[row_indexer, "col"] = values` instead, to perform the assignment in a single step and ensure this keeps updating the original `df`.

You are setting values through chained assignment. Currently this works in certain cases, but when using Copy-on-Write (which will become the default behaviour in pandas 3.0) this will never work to update the original DataFrame or Series, because the intermediate object on which we are setting values will behave as a copy.
A typical example is when you are setting values in a column of a DataFrame, like:

df["col"][row_indexer] = value

Use `df.loc[row_indexer, "col"] = values` instead, to perform the assignment in a single step and ensure this keeps updating the original `df`.
