Case 025 documents two major weather disasters on August 11, 1999: an F2 tornado in Salt Lake City and flash floods on Long Island. The dataset is curated by SCIOPS and archived at UCAR/JOSS/NOAA/CODIAC. It captures the event details from August 12, 1999.
Use Cases
- Analyze tornado path and intensity (F2 rating) using geospatial and temporal data from 18:45 to 18:55 UTC.
- Correlate reported hail size (1.5 inches diameter) with storm cell characteristics and damage reports.
- Model flash flood generation by examining rainfall rates (1-2 inches per hour) and estimated totals (3-5 inches) over a 4-hour period (13Z to 17Z).
- Study storm movement and clustering behavior along a warm front for the Long Island thunderstorm event.
- Assess societal impacts by examining data on fatalities, injuries, and property damage (e.g., swept-away cars) from both events.
Strengths
- Focuses on two well-documented, high-impact weather events from a single day.
- Provides specific event metrics: F2 tornado rating, 1.5-inch hail, and 1-2 inch/hour rainfall rates.
Limitations
- Unknown data volume, row count, and specific file formats.
- Temporal scope is limited to a single day, August 11, 1999.
- Geographic coverage is restricted to two specific U.S. locations.
