The impact of thermally induced valley/ridge circulations on the regional-scale transport of pollutants is examined using a modeling approach. The approach consists of applying a numerical meteorological model which provides the wind and turbulence fields used as input to a Lagrangian dispersion model. A variety of generic simulations were performed. Results indicate a significant effect of the...

In this study we address the question of whether regional gravity field modeling techniques of GRACE data can offer improved resolution over traditional global spherical harmonic solutions. Earlier studies into large, equatorial river basins such as the Amazon, Zambezi and others showed no obvious distinction between regional and global techniques, but this may have been limited by the fact tha...

The long-term goals of this project are to further the insight into the dynamics of submesoscale flow in the oceanic surface layer. Using the Regional Oceanic Modeling System (ROMS), we aim to understand the impact of submesoscale processes on tracer mixing at small scales and the transfer of energy towards the dissipative scales of non-geostrophic turbulence. An advanced understanding of surfa...

In this project our long-term goal is to determine the ways and degrees to which realistically complex oceanic and atmospheric simulation models have an irreducible imprecision, hence an irreducible uncertainty in their analysis and forecast products. This goal is a natural accompaniment to the goal of continuing the evolution of the Regional Oceanic Modeling System (ROMS) as a multi-scale, mul...

The current study focuses on the problem of determining investment attrаctiveness of countries by means of monitoring regional stock markets. The method of using the permutation entropy as a model of investment attractiveness estimation is suggested. We have calculated the permutation entropy for the time series of stock markets of countries for the period from 2005 to 2018. The countries with ...

We describe an approach to image interpretation which uses a dynamically determined interaction of prediction and observation. We provide a representational mechansim, built on our geometric modeling scheme which facilitates the computational processes necessary for image interpretation. The mechanism implements generic object classes and specializations of models, enables case analysis in reas...

In this study, the relationship between components of knowledge management on the basis of M. Mc olrvy model and social capital has been studied, statistical population consisted of employees of Ministry of Energy, who were selected among employees of Hamedan regional power and were 420 subjects. Research tool is a questionnaire and Spss statistical software is used for data analysis and struct...

This special issue on \Regional weather models" complements the Oc-tober 1995 special issue on \Climate and weather modeling", which fo-cused on global models. In this introduction we review the similarities and diierences between regional and global atmospheric models. Next, the structure of regional models is described and we consider how the basic algorithms applied in these models innuence ...
