Abstract. A time series of mean-sea-level pressure was built from observations performed in Trieste 1 January 1841 to 31 December 2018. Original historical documents provided information on the instruments and observation sites. Mercury barometers have always been available. Until 1877 they represented only operation, while 1878 onwards barograph records became The consists mean daily values th...

due to the location of a domestic, industrial and agricultural zone near the caspian sea, this water body has long been under pressure and environmental threat. as a result of development of oil production activities in caspian region, such as oil exploration and extraction, a large volume of oil related pollutants is released annually into this important water body. considering the fact that h...

i introduction convective systems are atmospheric events that are associated with hazardous consequences, such as strong wind drafts, lightning, heavy rainfall, hail, or even tornado. they are manifested in the atmosphere within a broad range of spatial and temporal scales. a convection cell is composed of two distinct regions: the actual convective part which consists of the coldest intense ve...

[1] Monthly sea levels from five Arctic Ocean Model Intercomparison Project (AOMIP) models are analyzed and validated against observations in the Arctic Ocean. The AOMIP models are able to simulate variability of sea level reasonably well, but several improvements are needed to reduce model errors. It is suggested that the models will improve if their domains have a minimum depth less than 10 m...

[1] We present sea level spectra computed from bottom pressure records at two locations around the Balearic Islands, Western Mediterranean. In these spectra, several sea level oscillation peaks are observed at both sides of Mallorca Island. Moreover, the relative magnitudes of the first two peaks switch during the ‘‘rissaga’’ events. To understand the appearance of these modes and their changes...
