This dataset contains East Coast Lows cyclone tracks and cyclone phase space (CPS) parameters for the low pressure systems detected in the NARCliM regional climate model (RCM) ensemble simulations.
Each files contains data for one RCM simulation. The file name format is tracks_cps_GMC_RCM_PERIOD.nc, where GCM stands for the Global climate model used as focing, RCM is the version of the RCM used to run the simulation and PERIOD stands for either the historical (1990-2009) or the future climate (2060-2079) simulations.
Each row in the files contains the following fields:
1. the sequential track number
2. the date in the format YYYYMMDDHH
3. the cyclone center longitude
4. the cyclone center latitude
5. the value of the pressure minimum
6. the value of the lower troposphere thermal wind CPS parameter -VTL
7. the value of the upper troposphere thermal wind CPS parameter -VTU
8. the value of the symmetry CPS parameter B
