Low visibility, associated with fog, severely affects land, marine, and air transportation. Visibility is an important indicator to identify different intensities of fog; therefore, improving the ability to forecast visibility in fog is an urgent need for social and economic development. Establishing a proper visibility parameterization scheme is crucial to improving the accuracy of fog forecast operation. Considering various visibility impact factors, including RH, Nd, D, LWC, the parameterization formula of visibility in fog, as well as their performance in meteorology operation, are reviewed. Moreover, the estimated ability of the visibility parameterization formulas combined with the numerical model is briefly described, and their advantages and shortcomings are pointed out.

Transformations in the sphere of federal relations concern the most important directions of the reforming processes in the country. However, not all proposed and actually developing components of the federal reform seem well-argued and corresponding to long-term, strategic interests of the Russian statehood. The basic course of reform should meet the objective requirements of further decentralization of governing economic and social processes and the need to ensure strengthening the responsibility of RF subjects’ executive bodies and local self-management for steady social and economic development of their territories. The solution of these problems calls for a new model of federal policy of regional development, specification of some important components of the municipal reform as well as inserting certain amendments into the system of intergovernmental fiscal relations in order to stir up their stimulating function.

The article contains a general comparative study of four strategies of social and economic development: "Inertia", "Renter", "Mobilization", and "Modernization". The context for comparison is explanation of correlation between adaptive features of Russia’s contemporary economic system and particularities of the mentioned strategies with corresponding ways of managing economic development problems. The comparison is based on description of strategies essence, ways and tools to achieve results. Perspectives of achieving strategic purposes as well as expected results of implementation of each strategy are shown. Special comparative study of four strategies on the base of development of competitive markets as one of strategic aims of the Russian government is presented.

The article on the basis of extrapolation of system laws of management of social and economic development illustrates the system reason of the Cobra effect, that is, a situation where, despite the rather attractive goals that managers formulate, the result of the activities of subordinates is opposite to what was intended. The main problem of management is the development of a system of indicators, in which, working on the indicator, employees would change the state in the right direction. The reason for the Cobra effect is the manifestation of systemic patterns of socio-economic development. The main system regularity is the desire of the system for stability and self-preservation. This state of the system is achieved using the least energy-consuming way. It is shown that any worker, realizing system regularities, aspires to stability and self-preservation. Therefore, the employee is always forced to work for achieving the indicator. The article analyzes the manifestation of these laws at the level of enterprises and state. When managers understand these patterns explicitly or covertly, changes in the economic system are moving in the right direction. It is shown that the existing system of target indicators used as indicators to assess the effectiveness of management does not meet the goals and objectives of socio-economic development. At the meso- and macrolevel, absolute, volumetric indicators, such as gross national product and others, reduce the range of benefits to the population. The article defines the vector of change in the system of indicators for assessing the effectiveness of management at the regional and state levels, based on the fact that the key element is the family. At the same time, the targets should be indicators to assess the availability of benefits for households.
