Daily maximum temperature records from Melbourne and Perth between January 1972 and June 1991 identify unusually cold days. The dataset includes trajectory points for air parcels reaching the cities during these cold events. Analysis from referenced papers identified 13 outbreaks for Melbourne and 10 events for each city in winter and summer.
Use Cases
- Identifying extreme cold weather events based on daily maximum temperature records.
- Analyzing synoptic patterns associated with cold outbreaks, such as 'classic', warm front, and blocking anti-cyclone types.
- Examining air parcel trajectories to determine source regions for cold air outbreaks.
- Studying the relationship between Antarctic atmospheric organization and cold events in southern Australia.
Strengths
- Data covers a defined period from January 1972 to June 1991.
- Analysis identified 13 cold outbreaks for Melbourne and 10 events for each city in winter and summer.
- Includes trajectory data points for air parcels during cold events.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
