Search for tropical cyclone events using attribute filters

You can find events in the stochastic catalog data and historical data that meet your specific set of event attributes.

With Catalog Viewer, you can find events in the catalog that affect specific regions or pass through selected geographic areas. It also helps meet a specified set of criteria of industrial losses at the event level and a specified set of parametric filters having a defined range of central pressure range, forward speed, radius, and wind speed. You can specify up to three filters at one time. Each filter set can include a range of industry losses, parametric filters, and up to three spatial filters.

You can also now leverage on the parameters of the North Atlantic historical tracks to better assess upcoming events and query tropical cyclone tracks from the Verisk’s catalog. For each historical event set, you will have access to Full Tracks, Intensity Footprints of wind speed, Hourly Point Data, and Event Summaries. You may also create your own collection of events of your interest for further visualization on maps.

Only for events in North Atlantic Historical Hurricane Catalogs, the search for events using attribute filters will now yield both stochastic event sets and historical event sets. For others, it will only yield stochastic event sets.

Note: Industrial losses are now available for 10K United States Hurricane Catalog,US Standard Historical Catalog and US Historical EDS(Extreme Disaster Scenario) and RDS(Lloyd's Realistic Disaster Scenario)Event Sets.
Steps to search for events using attribute filters:

Procedure

  1. Click on the add symbol next to TROPICAL CYCLONE
    QUERY BY search window opens
  2. Click on the Event Catalog.
    QUERY BY EVENT CATALOG search window opens enabling Select a Catalog Region and Set Event Conditions Filterset 1 options. Additionally, for US Tropical Cyclone 10K Stochastic Catalog, the search will also enable Industry Loss(USD Millions) filter option. .
  3. In the Select a Catalog Region drop-down list, select the catalog that contains the events of your interest, for example, 10k United States. From this release, Catalog Viewer is fully compatible with version 12.0 of Touchstone.
    You will get your licensed peril as the default.
  4. Click on Modify to update the Catalog Size.
    The Modify button will be greyed out, if there is only one set of event catalogs for the peril region.
  5. Further refine your Tropical Cyclone Type query by selecting either
    • WSST (Warm Sea Surface Temperature) or
    • STD (Standard)
  6. Provide the industry loss range, if you would like to use them as a filter.
    • You can either manually drag the scroll bar within the desired limits.
    • Or you can input the maximum and minimum numerical values.
    Note that the filter will be only active for 10k U.S. Tropical Cyclone catalogs.
  7. Name your parametric filter set.
    1. Click on the Filterset Options
    2. Click on to Edit Set Event Conditions Name to provide a name to the parametric filter set.
    3. In the text box, type a new name for the Filterset.
    4. Optionally, click on the Clear Filterset Name to clear the text box.
  8. Enable the Return 'at landfall' only option.

    If you do not enable the option, the application returns events that meet the filter criteria at any hourly point in the event trajectory.

  9. Specify the range for the event parameters used as filter criteria. For each parameter, you can:
    • Either manually drag the scroll bar within the desired limits.
    • Or input the maximum and minimum numerical values.
  10. Optionally, Include a Spatial Filter to specify the spatial data to be used as filter criteria:
    1. Click on the Include a Spatial Filter.
    2. Enable the Return spatial criteria 'at landfall' only to return only those events that meet the criteria.
    3. From the Select Map Layer* drop-down list, select a map layer.
    4. Optionally, drag the Include Buffer to right to include additional locations positioned within the buffer limit. Input the distance information in absolute numbers in the Distance* field and select the unit of measurement from the drop-down list
      A shape corresponding to the buffer size measurements will be visible on the map. You can add up to three buffer extents on recently added map layers, with each extent overlaying the additional spatial filter selected during your event search.
    5. Click on the to remove the selected map layer from the filter criteria.
    6. To include additional spatial filters, click on the another Include a Spatial Filter placed below the initial one and repeat the previous steps.

      You can add up to three spatial filters in each filter set.

  11. Optionally, to add another set of parametric and spatial filters, click on the Add a Filterset and repeat steps 4 through 7.
  12. Click the Run Query for initiating the event search.
  13. Alternatively, click on the Reset to clear all the search inputs.
  14. Optionally, select a new stochastic catalog from the Select a Catalog Region drop-down list to explore Event Ids from alternate target catalogs.

Results

The application retrieves both stochastic and historical events that meet the criteria specified in all filter sets. But for each filter set, the application searches for events that pass through any of the spatial filters.

Next Steps

Click on Close to get back to the main search window.
Note: Note that whenever you navigate from one peril search to another, you will receive a warning message informing you that all of your current peril data and related map layers will be cleared.
