TRAM: el nuevo modelo numérico de Meteo-UIB adecuado para todo tipo de predicciones atmosféricas regionales

Abstract

A new limited-area numerical model, TRAM (Triangle-based Regional Atmospheric Model), has recently been developed at Meteo-UIB. The model utilizes a nonhydrostatic and fully compressible (NHFC) version of the Navier-Stokes equations and incorporates numerous original characteristics. In this work, it is presented and validated through numerous 2D and 3D tests. TRAM performs as well as state-of-the-art models and is suitable for simulating circulations ranging from small-scale thermal bubbles to synoptic-scale baroclinic cyclones, including orographic circulations, thermally driven flows, squall lines, supercells, all kinds of precipitation systems, and medicanes. Besides opening a myriad of academic and research applications, TRAM regional forecasts at different resolutions are available at https://meteo.uib.es/tram
