In the North Atlantic lies one of the world’s largest climate mechanisms: a system of currents transporting relatively warm water from the tropics to the poles, with return currents at depth transporting colder, denser water further south. The transport of heat to the North Atlantic keeps the UK’s

We will bring more updates as we have them this week, and will be releasing the full May and Spring 2025 statistics on Monday 2 June.” How do we know when records are broken? The answer lies in a Met Office dataset that's been quietly mapping our weather history for around the last two centuries.

In turn, this affects some other variables (e.g. the amount of lying snow, which leads to colder winter temperatures, and hourly precipitation extremes) and leads to differences that are significant 1 .

Fixing the graupel code error impacts winter temperature in some regions, due to more lying snow in the modified
