Short summary
The study assesses the practical predictability of an extreme rainfall event on 8 to 12 December 2018 over central Vietnam using quantitative precipitation forecasts (QPFs) from a time-lagged cloud-resolving ensemble system. To do this, 29 time-lagged (8 d in the forecast range) high-resolution (2.5 km) members were run every 6 h from 3 to 10 December 2018. Results reveal that the cloud-resolving model predicted the rainfall fields in the short range (less than 3 d) for 10 December (the rainiest day).

Short summary
A record-breaking rainfall event over central Vietnam is investigated. Key factors include the combined effect of northeasterly wind, easterly wind blowing to central Vietnam from the western North Pacific (WNP), southeasterly wind, local topography, and high sea surface temperature (SST) over WNP and the South China Sea (SCS). The cloud-resolving storm simulator (CReSS) is applied to simulate this event. The results show that the model mostly captured the quantitative rainfall of this event.

In this study, cloud-resolving simulations are performed under idealized and uniform southwesterly flow direction and speed to investigate the rainfall regimes in the Mei-yu season and the role of complex mesoscale topography on rainfall without the influence of unwanted disturbances, including a low-Froude number regime where the thermodynamic effects and island circulation dominate, a high-Froude number regime where topographic rainfall in a flow-over scenario prevails, and a mixed regime.

Short summary
This study indicated that the Cloud-Resolving Storm Simulator (CReSS) model significantly improved heavy-rainfall quantitative precipitation forecasts in the Taiwan Mei-yu season. At high resolution, the model has higher threat scores and is more skillful in predicting larger rainfall events compared to smaller ones. And the strength of the model mainly lies in the topographic rainfall rather than less predictable and migratory events due to nonlinearity.

The study introduces "Storm Tracker," a budget-friendly device for weather observation. It highlights the calibration and testing against more expensive devices, ensuring its accuracy for temperature and humidity. This innovation could improve weather forecasting by making detailed atmospheric data more accessible, especially in challenging regions. Through rigorous comparison and enhancement, "Storm Tracker" promises to improve disaster preparedness and understanding of local weather patterns.

Short summary
The extreme rainfall event (645 mm in 24 h) at the northern coast of Taiwan on 2 June 2017 is studied using a cloud model. Two 1 km experiments with peak amounts of 541 and 400 mm are compared to isolate the reasons for such a difference. It is found that the frontal rainband remains fixed in location for a longer period in the former run due to a low disturbance that acts to focus the near-surface convergence. Therefore, the rainfall is more concentrated and there is a higher total amount.
