Introduction

This document details the enhancements requested and required for TCRM. It serves as a guide to the development team as to what elements need to be modified, created or upgraded to ensure Geoscience Australia delivers a quality product. Some of the enhancements are already underway, while others will require significant scientific and software development and may be several years from implementation. Each section gives a summary description of the issue, the requirements to be satisfied, any constraints that may need to be considered, and the current status of the enhancement. Sections may be added or removed over time as new enhancements are requested by users and others are implemented.

Storage of event sets

Currently TCRM generates an annual event set for a user-selected number of years. For each annual event set, the tracks and wind fields are stored in a single file (include example wind field image indicating existence of multiple events in a single file). Often, users will be interested in the idea of “what does a 1-in-100-year event look like for my location?” To enable users to interrogate individual events in this manner, each event needs to be stored as a separate entity. This capability will also allow users to analyse event losses and return period losses in sub-national regions (upon integration with the HazImp tool).

Requirements

  • Statistical module to calculate date (day-of-year) genesis statistics;
  • Incorporate date information in track generation;
  • Track generation model to sample environmental pressure from 3-dimensional long-term mean climatology (day-of-year, lon, lat);
  • Each event to have unique identifier (e.g. serial number) that is recorded in the track file and wind field file;
  • Hazard module to ingest individual wind field files (i.e. not annual maxima as at present);

To enable rapid selection of events, an event catalogue should be generated, which records key attributes of each event (including, but not limited to: genesis longitude/latitude, genesis date, event identifier, maximum intensity [wind speed and central pressure], total lifetime of event).
