Figure 1: Trends in mid-atmospheric geopotential heights. We next explore the extent to which trends in mid-atmospheric circulation patterns have influenced the likelihood of temperature extremes. For ...

This study investigated the extratropical circulation anomalies responsible for cold surges over the South China Sea in winter. The surge events were identified by the intensity of northerly winds ...

(a) Northwest type, (b) Southeast type, and (c) Southern Himalayas type. “C”: cyclonic circulation anomaly. “A”: anticyclonic circulation anomaly. The green arrow indicates moisture transport and its ...

ABSTRACT:This paper analyses atmospheric surface circulation and climatic extremes in the Iberian Peninsula in winter (December–February). Sea level pressure grids (1850–2003) are classified through a ...
