Evaluación de la respuesta del modelo WRF a diferentes configuraciones físicas en el modo de convección permitida para Andalucía

Abstract

Convection Permitting Models (CPMs) are a significant advancement for conducting climate simulations with fine-scale resolution (<4 km). Microphysics (MP) and cumulus (CU) dynamics play crucial roles in climate patterns at these scales. Evaluating CPM performance in regions with complex terrain is vital for understanding their response to diverse topographical and climatic conditions. This study focuses on analyzing simulations conducted using the WRF model over Andalusia, a complex region encompassing coastal areas, plains, and mountainous terrain. The experiments were based on two nested domains, one (d01) covering the Iberian Peninsula and the other (d02) focusing on Andalusia. A total of 12 schemes were run, combining three MP options (THOMPSON, WSM6 and WSM7) with four CU options (G3, GF, KF and OFF). Results show that simulations with GF or OFF in d01 exhibited superior performance, while THOMPSON performed better in high mountain regions. The WSM7-GF scheme emerged as the optimal configuration for Andalusia.
