蜜芽传媒 weatherman Nick Miller looks at the science behind what happened to Britain's weather in 2012. He meets the Met Office's Adam Scaife and meteorologist Len Shaffrey to find out why the jet stream's unusual behaviour had such an impact on the UK's weather in 2012.

The lowest temperatures of 2012 (up to October 2012) were in a cold spell during the first half of February. This was associated with high pressure across much of Europe bringing easterly winds.

By contrast, on 23 February the temperature widely exceeded 17C. It was the warmest February day since 1998.听

On 28 June, a line of intense thunderstorms originated in south Wales in the early morning. This moved across Worcestershire, Shropshire, the West Midlands and Leicestershire by late afternoon. The thunderstorms were associated with hot, humid air from a 'Spanish plume' ahead of frontal systems pushing in from the west. A man drowned in flood waters in Shropshire.

The warmest day of the year was 18 August.

Across the Midlands generally the period April to July was the wettest in the last 100 years. More than twice the average rain fell in April, June and July. Only the summers of 2007 and 1912 were wetter in the last 100 years.听

In contrast, the period April 2010 to March 2012 saw a prolonged drought, with less than 75% of average rainfall for 11 months through this 24-month period, causing problems for agriculture, the environment, and water resources.

听

The drought and subsequent exceptional wet weather brought a remarkable transformation to the hydrological outlook, from droughts, to floods.
