A simple yet accurate parameterization of spectral and broadband ocean surface albedo has been developed. To facilitate the parameterization and its applications, the albedo is parameterized for the direct and diffuse incident radiation separately, and then each of them is further divided into two components: the contributions from surface and water, respectively. The four albedo components are...

The radioactive species radon (222Rn) has long been used as a test tracer for the numerical simulation of large scale transport processes. In this study, radon transport experiments are carried out using an atmospheric GCM with a finite-difference dynamical core, the van Leer type FFSL advection algorithm, and two state-of-the-art cumulus convection parameterization schemes. Measurements of sur...

The physics- and initial-based ensemble approach for Weather Research Forecasting (WRF) model is applied predicting four different extreme precipitation events that occurred in summer autumn over the two most flood-prone regions of Turkey, namely; Eastern Black Sea (EBS) Mediterranean (MED). A total 48 runs, each which includes nested domains, designed considering microphysics (MP), three cumul...

The goal of this study is to transform the Harrington radiation parameterization into a transfer scheme or lookup table, which provides essentially the same output (heating rate profile and shortand longwave fluxes at the surface) at a fraction of the computational cost. The methodology put forth here does not introduce a new parameterization simply derived from the Harrington scheme but, rathe...

In a previous study, a daily evaporative fraction (EF) parameterization scheme was derived based on day–night differences in surface temperature, air temperature, and net radiation. Considering the advantage that incoming solar radiation can be readily retrieved from remotely sensed data in comparison with surface net radiation, this study simplified the daily EF parameterization scheme using i...

This paper presents a reference-based parameterization scheme for equation-based, objectoriented modeling languages such as Modelica. It is demonstrated, how simple language constructs can be designed that enable a general and powerful parameterization of models. Furthermore, the computational process required for this parameterization scheme is outlined. To validate our concepts, an experiment...

A minimal 3D numerical model designed for basic studies of tropical cyclone behavior is described. The model is formulated in s coordinates on an f or b plane and has three vertical levels, one characterizing a shallow boundary layer and the other two representing the upper and lower troposphere, respectively. It has three options for treating cumulus convection on the subgrid scale and a simpl...
