Assessment of parameters of mesoscale convective systems based on satellite and upper-air sounding database (West Siberia)

Abstract

Проведен анализ мезомасштабных конвективных кластеров (МКК) за период с 2008 по 2018 г. работы по наземным и спутниковым данным. Определены синоптические ситуации образования МКК и продуцирование опасных явлений, проведена оценка состояния атмосферы с помощью индексов неустойчивости KIND и LIFT. МКК формируется при средней и слабой степени неустойчивости атмосферы. Все МКК связаны с продуцированием грозы, доля ливней составляет 15% от общего числа случаев, сильного дождя -1%, града -7% и сильного ветра -5%.Ключевые слова: Западная Сибирь, мезомасштабный конвективный комплекс, спутниковая информация.

Analysis of the embedded convection of frontal cloud systems based on satellite and ground-based measurements

“…Due to this peculiarity, these cloud systems are practically invisible when observed from the Earth surface, so the most effective means of their study are mathematical modeling methods and Earth remote sensing (ERS) data 4 . At the same time, high recurrence of convective clouds was recorded in the south of Western Siberia 5 . Thus, the study of embedded convection and related phenomena in this area is relevant.…”

Application of active and passive satellite sensing data for analysis of embedded convection over Western Siberia

“…Due to this peculiarity, these cloud systems are practically invisible when observed from the Earth surface, so the most effective means of their study are methods of mathematical modeling and Earth remote sensing (ERS) data 7,8 . At the same time, high recurrence of convective clouds was recorded in the south of Western Siberia 9,10,11 . Thus, the study of embedded convection and related phenomena in this area is relevant.…”
