The impact of sea surface temperatures on a severe convective wind event in the East Australian Current system

This repository contains scripts and notebooks for analysis and modelling of a severe wind event in the Tasman Sea. This analysis is intended for inclusion in a research thesis (in preparation). The marine severe wind event was observed during the RV Investigator voyage Understanding eddy interactions and their impacts in the EAC.

1. Version 4.3 of the Weather Research and Forecasting (WRF) model is setup on the Gadi HPC system and run for a control case using this script (noting that one restart is also required using this script). Pre-processing and runtime WRF namelists for WRF simulations are available in the namelists directory.
2. Three experiments are performed using WRF, including with no latent heating from microphysics, a warm SST perturbation, and a cold SST perturbation. Several other WRF experiments were performed but are not presented in the research thesis.
3. Vertical cross sections are taken along several transects from WRF model output using this script. Options for transect bounds and orientation are determined by manual inspection of WRF output. These cross sections are averaged and visualised, and used to compare density current statistics between WRF simulations.
4. WRF output is compared with wind speed and radar observations from oboard the RV Investigator and cloud-top temperatures from the Himawari satellite.
5. Vertical profiles of temperature, wind, and moisture from the WRF model are compared with radiosonde observations
6. Calculate diagnostics of the large-scale convective environment from ERA5, and perform clustering based on a previous paper
