CMIP6 Model Cyclone Patterns over Northeastern U.S., 1980-2019

Northeastern U.S. extratropical cyclone activity and associated large-scale meteorological patterns from 1980 to 2019. The data includes composites of 500-hPa geopotential height and cyclone tracking outputs from five reanalysis products and CMIP6 historical experiments. It was created by Michelle Gore of Pennsylvania State University to evaluate climate model skill.

Use Cases

• Evaluating climate model skill in simulating cyclone frequency based on tracked extratropical cyclone events.
• Classifying accumulated cyclone activity based on large-scale meteorological patterns identified via self-organizing maps.
• Analyzing the relationship between geopotential height variability and cyclone intensity over the northeastern U.S.
• Benchmarking CMIP6 historical experiments against reanalysis data for pattern and event representation.

Strengths

• Includes data from five distinct reanalysis products for comparison.
• Covers a 40-year time period (1980-2019) for climatological analysis.
• Provides both raw tracking outputs and processed composites for each dataset.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
