An intense, stubborn area of high pressure over much of Europe, extending from Siberia in the east to the UK in the west has led to plummeting temperatures since the end of January 2012.
|From BBC Weather website|
This high pressure means clear, cloud-free days and cloud-free nights. When this happens at this time of year, it leads to a prolonged cold spell. As air descends, it dries out. This results in little or no cloud. By night, cloud acts as a blanket, stopping heat that is in the ground radiating away into the sky.
So, in February, we have short days, low heating of the ground, long nights and nothing to stop the heat from the ground escaping. These conditions have lasted for a long time, so it just gets colder and colder.
