Interannual change in summertime precipitation over northeast Asia

Abstract: The summertime precipitation over northeast Asia (Mongolia and Inner Mongolia) increased from 1980 to the mid‐1990s, and low‐precipitation summers continued for 4 years from 1999. A vegetation index based on satellite observations shows a similar interannual change. The first EOF mode of the interannual change of July precipitation shows a seesaw pattern between northeast Asia and Siberia, and the time coefficient represents the summertime precipitation change over northeast Asia. This mode is associated with … Show more

“…5b), implying that ω cannot explain the increasing trend in precipitation. Iwao and Takahashi (2006) pointed out that summertime rainfall is associated with a meridional circulation caused by a north-south pressure difference, which is a result of Rossby waves of different phases passing through Siberia and Mongolia.…”

“…Following the method of Iwao and Takahashi (2006), we investigated the difference in geopotential height (GPH) at 300 hPa between 39-53 • N (Mongolia) and 55-70 • N (Siberia). As presented in Fig.…”

“…Байкал с помощью разложения на естественные ортогональные функции (ЕОФ) выделены две преобладающие моды (Li et al, 2009;Iwao et al, 2006). Первая мода представляет собой качельное колебание осадков (seesaw mode) между Восточной Сибирью (ВС) и Монголией (М) (Iwao et al, 2006) (рис. 1) (область ЕОФ разложения ограничена 35-65ᵒ с.ш., 90-115ᵒ в.д.…”

“…Для того чтобы проиллюстрировать связь ВС-М моды и блокирова-ния рассмотрим два примера: июль 1993 и 1980 гг. Согласно (Iwao et al, 2006), в июле 1993 г. ВС-М была положительна (засуха в Восточной Сибири и экстремально высокие осадки в Монголии), в 1980 г. ВС-М имела обратный знак. Сопоставим аномалии осадков с положением блокингов в эти периоды.…”
