In this paper we consider the impact of Arctic air outbreaks on the weather and the performance of certain sectors of the economy of the Azov-Black Sea region. Special emphasis is made on risks these phenomena can pose to the operation of transport complexes and marine navigation. We propose a new technique to detect Arctic outbreaks that enables more reliable and precise identification of these phenomena. Its performance is tested by means of estimation of the total duration change trends for the outbreaks that occurred in the region in question during 2000–2018 period. Unlike the conventional detection technique, the proposed one is shown to significantly lower the probability of overlooking the phenomena in question, as well as minimize cases of other weather phenomena being mistaken for the Arctic air outbreaks. The trial use of the proposed technique has revealed that during the period from 2000 to 2018 the total duration of Arctic air outbreaks in the Azov-Black Sea region had a tendency to increase in January. The opposite trends have been observed in April. The most affected part of the region has been found to be the North-Western region of the Sea of Azov while the least affected is the West and the South-West of the Crimean Peninsula. Based on the results obtained, we conclude that the operational conditions for marine transport complexes functioning in the area tend to somewhat worsen in winter, whereas during other seasons they become more favorable. |
