Abstract:
... External water exchange of bays of the lakes Onega (Kondopoga and Petrozavodsk bays) and Ladoga (Hiidenselkä Bay), considering the exchange with the lake water, was assessed by water chemistry of the bays and inflowing waters, as well as by the volume of water inflow into the bays. The periods of water exchange were found to be 0.13 for Petrozavodsk Bay, 1.02 for Kondopoga Bay, and 1.15 year for H ...

Abstract:
... Governed by the Clausius-Clapeyron (CC) equation, daily mean temperature (Tm) and precipitation extremes would be theoretically linked by atmospheric moisture. However, precipitation extremes cannot systematically follow the CC rate of 7% per warming degree, due to moisture limitations. In this study, the observational tri-pole relation among Tm, atmospheric moisture and precipitation intensity ov ...

Abstract:
... The thermoelectric solar tower plants have had a great development in the last years, evolving from a few MWe to reach a hundred MWe. The location of these large plants in desert areas leads to very specific problems in their design and great uncertainty among CSP promoters. In particular, there is no reliable information on the losses due to solar extinction between the heliostats and the receive ...

Hydrological models claim to be able to reproduce typical temporal patterns of dominant processes using site-specific model parameters. Thus, patterns of temporal dynamics in dominant modelled processes and their ...

The study period included the 2015–2016 El Niño anomaly and the incidence of a highly energetic swell-storm. The sandbar responded directly to the seasonal wave forcing, thus, it migrated offshore during ...
