Parameterization of Near-Surface Turbulence Processes in Atmospheric Models: Past, Present and Future

Dear Colleagues,

The application of atmospheric boundary layer studies arises in many areas such as regional weather forecasting, air pollutant dispersion, and air quality assessment, and prediction of track and intensity of the tropical cyclone. One of the key challenges for operational models to accurately forecast daily weather and air quality is the adequate representation of boundary layer processes in the atmospheric models. Although significant progress has been made in this direction, proper representation of various turbulence regimes in the atmospheric boundary layer still present challenges to numerical models. The uncertainty in the representation of these regimes is mostly because of our limited understanding of the near-surface atmospheric processes; that, in turn, is due to the lack of in-situ measurements required to characterize these processes.

This special issue will be focused on original research related to observational and theoretical studies of the atmospheric boundary layer process and related application studies. We also welcome a detailed review papers related to the current status of parameterization of near-surface turbulence processes in the atmospheric models.

Relevant topics include, but are not limited to:

1. Improved understanding of near-surface atmospheric processes through the analysis of in-situ measurements.
2. Parameterization of surface fluxes of heat momentum and moisture in weather and climate models under varying atmospheric stability conditions.
3. Modeling and theoretical studies of surface-atmosphere interaction processes and their significance in air-quality and dispersion modeling.
4. Studies related to the sensitivity of the climate model projections to the representation of atmospheric boundary/surface layer processes.
5. New observational datasets and microscale scale CFD modeling for atmospheric boundary layer.
