The Met Office have released their 3rd annual State of the UK Climate report, which is an annual publication providing an up-to-date assessment of UK climate trends, variations and extremes based on the latest available climate quality observational datasets.
The report shows that 2016 was the 13th warmest year in records dating back to 1910. For the UK as a whole, 2016 was 0.5ºC warmer than average (1981-2010), whilst the last decade was 0.3ºC warmer and sunshine levels were 4% higher.
The Fujiwhara effect describes the rotation of two nearby - within about 1,200km - storms around each other and a common midpoint (anti-clockwise in the northern hemisphere).
The Fujiwhara effect was named after Sakuhei Fujiwhara, who described a paper about symmetrical motions in the atmosphere in 1921
The last few years have seen several rainfall events causing widespread flooding in the UK, such as the extensive flooding in winter 2013/14 when the heaviest rainfall in 100 years fell southern England and the Midlands, and the flooding in the north-west as a result of Storm Desmond in December 2015.
