UWLCM is a large-eddy simulation (LES) model of clouds developed at the University of Warsaw. I will present a brief overview of the model for those not familiar with it. Next, I will discuss recent developments of the model associated with our involvement in the NextGEMS project. These developments include a novel subgrid-scale (SGS) model based on fractal reconstruction of SGS fields, and the implementation of an anisotropic Smagorinsky turbulence model. I will present preliminary results from an ongoing study examining the sensitivity of stratocumulus clouds to the anisotropic SGS model, aimed at enhancing the representation of these clouds in global storm-resolving models, particularly at "grey-zone" resolutions with highly anisotropic grid cells. Finally, I will discuss future plans for incorporating ice microphysics and numerical improvements, including adaptations to new computing architectures and optimizations, as part of the HANAMI project.
