current state can have big influences on the future forecast. That’s why forecasts are updated regularly using the latest data and insights. These updates help keep the forecast accurate and aligned with current conditions and expectations. Comparing global models Meteorologists at the Met Office use

of water vapour. High humidity makes it very hard for sweat to evaporate from our bodies which means that we cannot cool down. For people working outside or in overheating buildings, especially where the work is physically demanding, humid heat is a big problem. The world is getting warmer, and many
orography suggest it does not make a big difference, but sub-grid terms might still do. • The GungHo dynamics have different conservation properties. We are trying to reproduce this effect in the UM by tweaking the ‘fountain-buster’ setting in the convection scheme. Mean orography (m) Figure 9: native

Southern Ocean clouds are very important for the global energy budget, but are poorly understood. The mean austral summer time bias: Incoming
Committee, direct greenhouse gas emissions from buildings were around 17% of the UK total in 2019. Lowering demand for heating homes can help reduce this through insulation and smart heating controls. A bigger shift, however, is required in terms of the fuels used to heat homes. Approximately 74

Nigel said: “We need to do the things we know we can do on a bigger scale, like making our landscapes more natural, making them more flood resilient, and our towns and cities
