Embedding-based representations can make these data searchable through similarity search and analog retrieval, but nearest neighbors in latent space are not automatically scientifically meaningful. Researchers need tools to inspect how embeddings organize meteorological data, compare representation models, develop retrieval strategies, and verify results against physical evidence. We present an open-source visual analytics workbench for inspectable, configurable, and scalable embedding-based search over weather and climate data. The system links embedding experiments to source data, metadata, spatial context, model configurations, and retrieval parameters, allowing users to explore latent spaces, construct global or localized queries, and inspect retrieved analogs through meteorological views. We demonstrate the workbench through tropical-cyclone retrieval using ERA5 derived embeddings and IBTrACS metadata, and evaluate its out-of-core retrieval backend to show that large embedding collections can be searched beyond in-memory limits on commodity workstation hardware. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png Binary dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral ECMWF ERA5 > ECMWF ERA5 Atmospheric Reanalysis U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-29 revision 23.8 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > WEATHER EVENTS > TROPICAL CYCLONES U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-29 revision 23.8 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 2.226 https://gdex.ucar.edu/datasets/d041308/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d041308/dataaccess/ https Data Access Related Link download none asNeeded
