Evaluation and assessment of freshwater quality of lakes, rivers and reservoirs is a complex technical operation. These assessments at present need to be done at local, regional and global levels (McCarthy et al., 2001). Since aquatic ecosystems worldwide are under anthropogenic stress, limnological studies are necessary for evaluation of these stresses and to develop tools to convert speedily ...

To quantify the effects of recent and potential future decreases in surface wind speeds on lake thermal stratification, we apply the one-dimensional process-based model MyLake to a large, shallow, polymictic lake, Võrtsjärv. The model is validated for a 3-year period and run separately for 28 years using long-term daily atmospheric forcing data from a nearby meteorological station. Model simula...

A theoretical model interpreting propagating disturbances of EUV emission intensity, recently observed in coronal loops, is constructed in terms of slow magnetoacoustic waves. The model is one-dimensional and incorporates effects of nonlinearity, dissipation due to finite viscosity and thermal conduction, and gravitational stratification of plasma in the loop. It has been found that, for the ob...
