Sažetak
The paper aims to test the sensitivity of high-resolution mesoscale atmospheric model to fairly reproduce atmospheric processes that were present during the Boothbay Harbor meteotsunami on 28 October 2008. The simulations were performed by the Weather and Research Forecasting (WRF) model at 1 km grid spacing by varying initial conditions (IC) and lateral boundary conditions (LBC), nesting strategy, simulation lead time and microphysics and convective parameterizations. It seems that the simulations which used higher-resolution IC and LBC were more successful in reproduction of precipitation zone and surface pressure oscillations caused by internal gravity waves observed during the event. The results were very sensitive to the simulation lead time and to the choice of convective parameterization, while the choice of microphysics parameterization and the type of nesting strategy (one-way or two-way) was less important for reproducibility of the event. The success of WRF model appears limited to very short-range forecasting, most advanced parameterizations, and very high-resolution grid spacing ; therefore, the applicability of present atmospheric mesoscale models to future operational meteotsunami warning systems still have a lot of room for improvements.
