After a short hiatus, the Mostly Weather podcast returns to investigate a subject dear to the British public’s hearts – rain. To start, as is tradition, we identify what exactly rain is and look at rain’s ‘recipe’. We also looks at the world's wettest areas, the different types of rainfall and how we measure it. We are also joined by climate scientist Dr Lizzie Kendon who gives us a fascinating insight into her work around the use of high-resolution models to better understand extreme rainfall.
