<p>Exploiting the Delaunay interpolation, we present a newly implemented 2-D sea-level reconstruction from coastal sea-level observations to open seas, with the aim of characterizing the spatial variability of the rate of sea-level change. To test the strengths and weaknesses of this method and to determine its usefulness in sea-level interpolation, we consider the case studies of the Baltic Sea and of the Pacific Ocean. In the Baltic Sea, a small basin well sampled by tide gauges, our reconstructions are successfully compared with absolute sea-level observations from altimetry during 1993-2011. The regional variability of absolute sea level observed across the Pacific Ocean, however, cannot be reproduced. We interpret this result as the effect of the uneven and sparse tide gauge data set and of the composite vertical land movements in and around the region. Useful considerations arise that can serve as a basis for developing sophisticated approaches.</p>

Abstract This article analyzes the opportunities of the Chinese initiative “One Belt, One Road”, for the development of the Baltic Sea macro-region (BSR), as a single transport cluster. One of the objectives of the initiative is to strengthen transport linkages from the Pacific Ocean to the Baltic Sea Region. Thus, the contemporary macro-regional approach to the development of EU macro-regions can provide an additional impulse to the creation of formal macro-regional inter-cooperation, via in this case, the project that will advance the transport infrastructure of the region. This study examines the situation of the railway sector in the BSR in the period 2004–2015, through hierarchical cluster analysis, to identify countries with similar trends in cargo flow turnover. Taking into account the favorable geographical position of Poland, its transport performance and advanced (in comparison to other Baltic Sea region countries) relations with China, it is concluded that Poland’s conditions are more suitable to promote economic integration with its closest neighbors – the Baltic countries-through the creation of formal macro-regional railway transport within the Rail Baltic project.

Abstract. Very dry high-ozone layers have been repeatedly observed with the ozone lidar in Garmisch-Partenkirchen (Germany) starting one or two days after the onset of high-pressure periods during the warm season. These episodes have been analysed by trajectory calculations and extended simulations with the FLEXPART particle dispersion model. Mixed contributions from the stratosphere over the Pacific Ocean and the boundary layers of East Asia and North America were found. The stratospheric influence is mostly dominating and caused by a rather shallow transfer from the stratosphere into these rapid upper- and mid-tropospheric air streams. The considerable vertical extent of these layers and peak ozone mixing ratios between 80 and 150 ppb suggest an important mechanism for stratosphere-to-troposphere transport.
