What’s behind our shifting weather patterns? Study identifies key causes of ocean circulation change

Pattern of ocean currents may be responsible for warmer weather in north-west Europe. By Conrad Duncan

The UK has enjoyed a wave of hot weather in recent days, with meteorologists recording three successive warmest days of the year this week (PA)

Researchers have identified the key factors that influence a vital pattern of ocean currents which many scientists believe brings warmer than usual weather to the UK.

The Atlantic meridional overturning circulation (AMOC), which carries warm water from the tropics northwards, is thought to be responsible for warmer temperatures in north-west Europe.

However, climate models have suggested that the AMOC is likely to weaken over the coming decades, presenting widespread implications for the regional and global climate.
