Britain is the rainiest country in western Europe, and if you live in the west of the country you are likely to be drenched more often than in the east. The Great British Weather, presented by Alexander Armstrong, coming live from the stunning location of Ullswater in the Lake District, investigates why. Chris Hollins visits Rain Gauge Cottage, Britain's wettest home; and EastEnders' erstwhile bad boy Larry Lamb explores the history of the classic weather icon, the humble umbrella. But it's not all downpours... Carol Kirkwood heads to the skies, getting up close and personal with the weather as she hang-glides into the heart of an enormous cumulus cloud.
