Study of wind field under sea breeze conditions; an application of WRF model
Atmospheric Research, 2010Co-Authors: D. K. Papanastasiou, Dimitrios Melas, I. LissaridisAbstract:Weather Research and Forecast (WRF) model is applied to study the wind field over the east coast of central Greece under typical summer conditions. This study aims at identifying the major features of the sea breeze circulation that is very frequently developing in the area during the warm period of the year and at verifying the model's ability to simulate the complex flow that is strongly influenced by the complicated coastline and very steep terrain. The simulation is carried out for a five-day period, characterized by sea breeze development. It is found that a complex Meteorological Phenomenon is evolving in the area, as two circulation systems are successively developing, the first over Pagasitikos Gulf, which is overridden by the system that develops later over the Aegean Sea. The major characteristics of the wind patterns and especially the sea breeze systems are identified and discussed. Additionally, the impact of topography and slope on sea breeze circulation is also commented. Model predictions agree fairly well with the observations taken at a near-surface Meteorological station.

Meteorological Phenomenon as a key factor controlling variability of labile particulate mercury in rivers and its inflow into coastal zone of the sea
Environmental Research, 2020Co-Authors: Karolina Gebka, Magdalena Beldowska, Dominika Saniewska, Ewa Korejwo, Michal SaniewskiAbstract:Abstract Mercury (Hg) is recognized as a global pollutant, which can be transported to the sea by suspended particulate matter (SPM) via rivers constituting the main source of mercury in the southern Baltic sea. The aim of the present study was to characterize the mercury fractions in suspended particulate matter, as well as the transformations of Hg during its riverine transportation into the sea. The thermo-desorption method was used to determine the labile and stable mercury fractions in SPM of rivers (Reda, Zagorska Struga, Gizdepka, Plutnica) within the Baltic Sea basin. In this paper six “periods” were designated (heating, non-heating, drought, rains, downpour/flood and thaws), during which the river suspended particulate matter was enriched with various fractions of mercury. Meteorological and hydrological phenomena such as downpours and thaws intensified surface runoff, causing an increase in the share of Hgabs and Hgads1 mercury fractions in suspended particulate matter. Whereas, droughts contributed to the formation of HgS in a large river and to an inflow of adsorbed Hg in smaller rivers decrease of air temperature leads to increase of fossil fuel combustion and then increases the share of adsorbed Hg (mainly bound with halides) in riverine particulate matter. In the non-heating season, the main fraction was the mercury absorbed inside organic matter.

Diurnal Water Content Changes in the Bare Soil of a Coastal Desert
Journal of Hydrometeorology, 2004Co-Authors: Nurit Agam, Pedro BerlinerAbstract:Abstract The deposition of dew is a common Meteorological Phenomenon that has been recognized as an important ecosystem element, especially in arid areas. There is some evidence that indicates that there is an increase in the water content of the topsoil during nights in which no dew deposition was observed. The purpose of this study is to describe the daily pattern of changes in water content in the upper soil layers and to identify the mechanism by which water is added to the soil (deposition or direct absorption). Moreover, the gains in soil water content during the night are compared to the dew amounts recorded by the Hiltner balance, and the losses and gains of water in terms of easily measurable environmental parameters are parameterized. Nine 24-h field campaigns took place during the dry season of 2002. During each campaign, the 100-mm topsoil was sampled hourly, and water content at 10-mm increments was obtained. MicroMeteorological measurements included incoming and reflected shortwave radiation...
