Common Remarks

The southward movement of cold air outbreaks from the Siberian-Mongolian High (SMH) are an important aspect of the intraseasonal variability of the winter monsoon. This cold and dry intrusion - often called "cold surge" - is associated with a rise in surface pressure, a sharp drop in temperature in China and a strengthening of northerly winds extending as far south as the equator.

As the surge moves southward, it often interacts with convection processes over the South China Sea, in the region north of Borneo, along the Indo-China coast and Java Sea. The severe weather accompanying the intense cold surge often brings about major disruptions of agricultural and economic activities in the affected regions.
