Реферат. В работе представлен анализ пространственно-временных характеристик климата, определявших накопление снега на автомобильных дорогах Томской области в 1966-2017 гг. Приведены результаты исследования характеристик снежного покрова, ветрового и метелевого режимов. Наметилось некоторое увеличение высоты снежного покрова на юге Томской области и снижение-на севере. Наблюдается уменьшение как числа дней с метелью, так и средней продолжительности метелей, обусловленное уменьшением скорости ветра. Ключевые слова. Накопление снега, автомобильная дорога, снежный покров, продолжительность метели, скорость ветра, ветровой режим.
Current climate changes in Russia are attended by the increase in frequency of dangerous weather events. This chapter researches long-term variations of the dangerous weather's events on Western Siberia and to reveal general regularity, which can be associated with forest fires. The researches have been carried out for the territories of southeast of Western Siberia. The duration of the fire season increases due to climate change. This is due both to the earlier snowfall and the onset of the phenological spring, and to the increase in the duration of the thunderstorm period. Thunderstorms in Siberia are a much more frequent cause of forest fires (28%) than in other territories. Wildfire frequency is correlated with air temperature and drought anomalies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
