Basic economic aspects of the efficiency of introduction of resource-saving technologies in the recreation area are considered. The role of resource-saving technologies in the overall energy budget of the region with the purpose to protect environment is examined.

Irrigated agriculture has the potential to alter regional to global climate significantly. We investigate how irrigation will affect regional climate in the future in an inland irrigation area of northern China, focusing on its effects on heat fluxes and near-surface temperature. Using the...

Cloud microphysical parameters, such as cloud droplet size (r), droplet number concentration (N<SUB align="right"><SMALL>d</SMALL></SUB>) and liquid water content (LWC), play an important role in the energy budgets of clouds, and thus the climate of the earth's atmosphere. The observations were collected during the North Atlantic...</small></sub>

The paper analyses, by applying a system of optimization models for cash flow analysis and forecasting, how effective a transfer of a part of the power generating capacities from gas to coal would be. We present a scenario analysis assuming both an increase of a gas export under a deficit of the...
