- 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)
