Abstract
  • The importance of low-level shear in the development of organized convective structures is well established in observations and numerical modeling. More generally, the formulation of quantitative relationships between the multiplicity of environmental parameters and measures of convective activity, by which to validate conceptual models, is an active field of research. With the intent to establish a baseline to interpret the variability of organized convective storms in response to changes in environmental conditions, we perform numerical experiments with a simplified non-hydrostatic model, with reference wind and thermodynamic profiles. For these idealized simulations, the non-hydrostatic model MOLOCH is reduced to a two-dimensional domain (x-z) with flat bottom and no soil physics, while diffusion and microphysics are the same used in the operational model, and a diurnal cycle is imposed, uniform over the domain. Preliminary results are given in terms of number and intensity of precipitation episodes for a range of numerical and physical parameters. (literal)
