Comparison of adaptive mesh refinement techniques for numerical weather prediction
Daniel S. Abdi, Ann Almgren, Francis X. Giraldo +1
This paper examines the application of adaptive mesh refinement (AMR) in the field of numerical weather prediction (NWP). We implement and assess two distinct AMR approaches and ev…
