The problem of the extension of the Siberian anticyclone towards Southeast Europe, and its relation to atmospheric circulation anomalies over the Northern Hemisphere

Winter temperature anomalies of the North China Plain and macroscale extratropical circulation patterns

“…Its intensity is especially important for the cold air outbreaks or cold surges that bring below-normal temperature to south and/or southeast China and therefore determine the temperature variation regime in the region (Ding, 1990). The Siberian high is also known to influence the circulation patterns over Eurasia (Makrogiannis et al, 1981), while its movement and intensity may be associated with certain macroscale circulation patterns (Ding and Krishnamurti, 1987). The ridge over Mongolia and Siberia in the mean elevation of the 700 hPa surface (Figure 6) may reflect the average location of the Siberian high.…”

Holocene flooding and climate change in the Mediterranean

“…The Siberian High (SH) is a shallow cold-core system that forms in October and persists until April, usually centred over northern Mongolia but during exceptionally high pressures it may extend with a ridge towards southeastern Europe and the Middle East (Lydolf, 1997). Extension of the SH westwards is associated with cooling of the air layer near the ground (Makorgiannis et al, 1981). Rogers (1997) studied North Atlantic storm-track variability and linked cyclogenesis in the Mediterranean with positive anomalies (strong) in the SH.…”

“…Rogers (1997) studied North Atlantic storm-track variability and linked cyclogenesis in the Mediterranean with positive anomalies (strong) in the SH. In other words, cold air from the SH extension mixes with the warmer air over the Mediterranean, creating a surplus of potential energy resulting in cyclogenesis (Makorgiannis et al, 1981). A study comparing a Siberian High index (SHI) with Northern Hemisphere teleconnection patterns (Panagiotopoulos et al 2005) reveals a correlation statistically significant at the 10% level of the SH index with other indices such as the Arctic Oscillation (AO), Polar/Euroasian (POL), and West Pacific (WP) patterns.…”

Cold windchill spells in the south Balkans: A study of the synoptic situations

“…(ii) Siberian ridge. This is an extension of the Siberian anticyclone (see Makrogiannis et al, 1981), which sometimes reaches the Balkans and occasionally extends westward to connect with a high pressure system over the eastern Atlantic-this has been called 'der Axe des Kontinents' (van Bebber and Koppen, 1885) or in Greek literature the Voeikov axis after the late nineteenth century Russian climatologist. The air masses associated with these Siberian ridges bring very cold conditions to the south Balkans.…”
