Abstract

fetched live from OpenAlex

Выявление причин изменений повторяемости гроз, являющихся одной из причин ландшафтных пожаров, - актуальная проблема управления организационными системами. Известно, что значимое влияние на эти изменения во многих регионах оказывают перемены их термического режима. Управляют ими также вариации потоков космических лучей, проникающих в тропосферу, которые вызывают ионизацию воздуха. Такие потоки, как правило, повышены в районах, расположенных вблизи магнитных полюсов. За время осуществления наблюдений за положением Северного магнитного полюса выявлено его смещение из района Канадского арктического архипелага (территория Нунавут (Канада)), в направлении полуострова Таймыр (Сибирь) почти на 2500 км. В ХХI веке это смещение ускорилось, а повторяемость гроз над многими пунктами Сибири увеличилась, что позволяет предположить значимость причинной связи между изучаемыми процессами. Целью данной работы являлось осуществление такой проверки. При этом изучены изменения повторяемости гроз над пунктами Красноярского края, Якутии, а также территории Нунавут, которые расположены между параллелями 60ᵒ с.ш. и 65ᵒ с.ш. Установлено, что скорость увеличения средней повторяемости гроз для всех рассматриваемых пунктов территории Сибири в ХХI веке значимо превосходила этот показатель для любых пунктов территории Нунавут. Так как потепление местного климата в изучаемых пунктах Сибири и Канады было практически одинаковым, полученный результат доказывает, что влияние смещения Северного магнитного полюса на изменения повторяемости гроз над изучаемыми пунктами являлось значимым. Следовательно, при дальнейшем смещении полюса в том же направлении, повторяемости гроз над упомянутыми регионами Сибири, а значит и количества ландшафтных пожаров, возникающих на их территориях, существенно возрастут. Identification of the causes of changes in the recurrence of thunderstorms, which are one of the causes of landscape fires, is an urgent problem of management of organizational systems. It is known that these changes in many regions are significantly influenced by changes in their thermal regime. They are also controlled by variations in the fluxes of cosmic rays penetrating the troposphere, which cause air ionization. Such fluxes are usually increased in the regions located near the magnetic poles. During the period of observations of the position of the north magnetic pole, its displacement from the Canadian Arctic Archipelago (territory of Nunavut (Canada)) to the Taimyr Peninsula (Siberia) by almost 2500 km has been revealed. In the 21st century, this displacement has accelerated and the recurrence of thunderstorms over many points in Siberia has increased, which suggests the significance of a causal relationship between the processes under study. The purpose of this work was to carry out such a check. Changes in the frequency of thunderstorms over points in Krasnoyarsk Krai, Yakutia, and Nunavut, which are located between the parallels 60ᵒ N and 65ᵒ N, were studied. It was found that the rate of increase in the average thunderstorm frequency for all studied locations in Siberia in the 21st century was significantly higher than for any locations in Nunavut. Since the warming of the local climate in the studied points of Siberia and Canada was almost the same, the obtained result proves that the influence of the shift of the northern magnetic pole on the changes in the frequency of thunderstorms over the studied points was significant. Consequently, at further displacement of the pole in the same direction, the recurrence of thunderstorms over the mentioned regions of Siberia, and hence the number of landscape fires occurring in their territories, will increase significantly.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
