Annual Exceedance Probability

The probability of a threshold being exceeded once (or more) in any year.

Genesis

Formation of a tropical cyclone event.

Hazard

The magnitude of wind speed. TCRM generates a 3-second gust wind speed, at 10 metres above ground over open, flat terrain (an aerodynamic roughness length of 0.02 m).

Kernel density estimation

A non-parametric method to estimate the probability density function of a random variable.

Lysis

Termination of a tropical cyclone event. Can be caused by the tropical cyclone weakening through stochastic process, landfall decay or exiting the defined domain.

mpirun

mpirun is a runtime environment for the Message Passing Interface (MPI). See http://www.mcs.anl.gov/research/projects/mpi/

Pypar

PyPar is a python library that provides efficient and scalable parallelism using the message passing interface (MPI) to handle big data and highly computational problems. See http://github.com/daleroberts/pypar

Return period

The average time between exceedances of a given threshold. Compare to Annual Exceedance Probability.

Tropical cyclone

A tropical cyclone is a rapidly-rotating storm system characterized by a low-pressure center, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.
