Tropical cyclone tracks found using the CSIRO Direct Detection scheme on CMIP5 model outputs
This data collection consists of:
1. ASCII text files listing each tropical cyclone detected within output of a suite of CMIP5 models for the Pacific region contained by latitudes 20N to 40S, and longitudes 135E to 150W; and
2. Global images of tropical cyclone densities derived from these detections, presented as either days per year or storms per... more year for a 5 x 5 degree longitude/latitude grid.
All tropical cyclones detected using the CSIRO Direct Detection and tracking algorithm within the above domain are presented in space-delimited ASCII text files for each model. Three time periods are available to select:
- from 1981 to 2000 ("baseline" period used for projections);
- from 2081 to 2100 ("future" period used for projections); and
- from 1950 to 2100 (all data).
There are two image types for each coupled model data source, both based on densities of storms within a 5 x 5 lon/lat degree box for the respective 20 year period (either 1981-2000 or 2081-2100):
- images containing "days" in the file name show the number of days per year in which a tropical cyclone was detected within that box
- images with "number" in the file name display the number of separate storms per year detected within that box. less
Climate Change Processes
Tropical cyclone tracks are from the application of the CSIRO Direct Detection and tracking algorithm applied to the "plev" (pressure level-based) outputs of individual CMIP5 models.
We acknowledge the World Climate Research Programme's Working Group on Coupled Modelling, which is responsible for CMIP, and we thank the climate modelling groups for producing and making available their model output. For CMIP the U.S. Department of Energy's Program for Climate Model Diagnosis and Intercomparison provides coordinating support and led development of software infrastructure in partnership with the Global Organization for Earth System Science Portals.
