A brief analysis of the supercell storm in Croatia on 19 July 2023 Open
Supercell storms, or super-Cb, are powerful and long-lasting convective systems that can form within statically unstable air mass in favourable dynamic conditions. These severe storm types are characterized by one or more rotation updrafts…

A Statistical Approach to Surface SAR Fleet Distribution Optimization: A Case Study of Croatian Waters Open
The objective of this research paper is to propose a novel approach to the spatial distribution of the surface Search and Rescue (SAR) units in Croatian territorial waters using the A* algorithm. The developed model identifies the shortest…

Contribution to the Research of the Effects of Etna Volcano Activity on the Features of the Ionospheric Total Electron Content Behaviour Open
This research represents a contribution to the theory on the coupling of the volcanic activity and the ionospheric dynamics, represented by total electron content (TEC) patterns and their behaviour. The ionospheric response to the activity…

The Analytical Contribution to the Theory of Solar-induced Earthquakes: the Croatian December 2020 M=6.4 Case Study Open
Solar-induced earthquakes are a relatively new field of research of possible connection between events originating from Sun, and the Earth's lithosphere dynamics. This is a theory that tries to explain the temporal correlation between the …
