В хронологиях по светлым кольцам за период, обеспеченный метеорологическими наблюдениями (1944—1992), есть группа общих лет по Западной Сибири и западной части Средней Сибири, вторая группа общих лет приурочена к восточной части Средней Сибири, третья находится в Восточной Сибири. Повсеместно формирование светлых колец связано с низкой температурой вегетационного периода, а именно июня, июля и августа. Впервые выявлены различия в климатическом сигнале у светлых колец у лиственницы из различных географических районов Сибирской Субарктики. В Западной Сибири основное влияние на формирование светлых колец оказывают температуры конца вегетационного сезона (августа), а в восточной — температуры начала вегетации (июня). Различия в температурном отклике хронологий по светлым кольцам обусловлены повышением температуры июня и соответствующим увеличением кон-тинентальности климата с запада на восток. Выявлены группы светлых колец хронологий со сходным сигналом, которые делят Сибирскую Субарктику на пять крупных районов. Эти группы согласуются с группами древесно-кольцевых хронологий, выделенными для региона ранее.</p></abstract><trans-abstract xml:lang="en"><p>Larches form light rings on 18 study sites at the Siberian forest-tundra on 4000 km long profile. The chronologies of the light rings were built for the period provided by meteorological observations (1944-1992). One group of common years with light rings was found for area of Western Siberia and the western part of Central Siberia. The second group of common years is confined to the eastern part of Central Siberia. The third group is in Eastern Siberia. The formation of light rings is associated with a low temperature of June, July, and August. Differences in the climatic signal of larch light rings from different geographical regions of the Siberian Subarctic have been shown. Temperatures of the end of the growth period (August) have the main influence on light ring formation in Western Siberia, and of the beginning of the growth period (June)-in Eastern Siberia. Differences between temperature responses of light ring chronologies due to June temperature increasing correspond to the increase in continental climate from west to east in Siberia. Revealed clusters of light ring chronologies have similar signal and divide the Siberian Subarctic into five large areas. These five areas are consistent with the areas of tree-ring chronologies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>северная лесотундра</kwd><kwd>Сибирь</kwd><kwd>лиственница</kwd><kwd>светлые кольца</kwd><kwd>континентальность</kwd><kwd>температура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>northern forest-tundra</kwd><kwd>Siberia</kwd><kwd>larch</kwd><kwd>light rings</kwd><kwd>continentality</kwd><kwd>temperature</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке РФФИ (проект № 20-05-00569) и государственного задания Института экологии растений и животных УрО РАН № АААА-А19-119031890086-0.
