Early Online Release Graphical Abstract with highlights
- Deep convection over TMA is induced by the heat island (Fig. 1) and sea breeze (Fig. 2) during weak synoptic forcing simulated with the ARPS/T-TEB system and JMA global model inputs.
- The ARPS/T-TEB simulations of three deep convection episodes are similar to previous studies.
- Dissipation (phase) errors on hourly precipitation forecasts tend to dominate, though scores improved up to 300% within the advective time scale with JMA boundary and initial conditions.
- The goal of the study was to test the T-TEB scheme, recently implemented in the ARPS system.
- The T-TEB includes momentum transfer by buildings and constructions.
- Similar ARPS simulations for the Metropolitan Area of São Paulo (MASP) also include wind acceleration by buildings and structures.
