The paper presents the general safety analytical model of a complex technical system under the influence of the operation process including its operating environment threats related to climate-weather change process, The system operation process including environment threats under influence of climate-weather variable conditions is defined. Moreover, the safety model of multistate systems at variable conditions related to operating environment threats and extreme weather hazards is proposed. The conditional safety functions at the operation process including operating environment threats and related to climate-weather change process particular states, the unconditional safety function and the risk function of the complex system at changing in time operation and climate-weather conditions and other, practically significant, critical infrastructure safety indices are defined. Furthermore, the same safety indicators are defined for exponential systems.

The paper deals with the sea accidents that have occurred at the Baltic Sea port waters for last three decades. For each accident, the climate-weather change process state is fixed to examine the weather hazard influence on this accident. Moreover, the Baltic Sea port waters accidents caused by the extreme weather hazard states are described.

W artykule przedstawiono koncepcję zintegrowanego systemu ostrzegania kierujących przed zagrożeniami atmosferycznymi w ruchu drogowym. Autorzy skupili swoją uwagę na czterech zasadniczych stanach niebezpiecznych: mgła, śliska nawierzchni, gołoledź oraz silny wiatr. Zakres pracy obejmuje opis systemów akwizycji danych meteorologicznych, sformułowanie metodologii oceny stanów niebezpiecznych oraz charakterystykę możliwych do zastosowania metod i narzędzi do informowania kierujących o wykrytych zagrożeniach. Istotnym elementem pracy jest propozycja wykorzystania modelu FASST jako narzędzia do prognozowania temperatury nawierzchni. Połącznie możliwości oceny aktualnej sytuacji pogodowej z krótkoterminowa predykcją stanu nawierzchni umożliwia zwiększenie efektywności oraz skuteczności systemów osłony pogodowej. W ramach pracy dokonano również analizy danych z istniejących systemów osłony meteorologicznej.

In the article presented the concept of drivers warning system about weather hazards occurring in traffic network. The authors focused their attention on four main weather states: fog, slippery roads, black ice and strong wind. The scope of the work includes the description of the road meteorological data acquisition systems, the methodology formulation of unsafe conditions evaluation and the characteristics of the applicable methods and tools which can be used to inform drivers about the detected threats. An important element of presented paper is the proposal of using FASST model as a tool for predicting surface temperature. Linking the ability of assessing the current situation and short-term surface conditions prediction can increase the effectiveness and efficiency of the weather protection systems. As part of the work, as an example, data from existing meteorological systems were analyzed.
