The map shows a clear divide between the north-west and south-east of the UK. The prevailing warm moist westerly winds mean that the west of the UK is more likely to receive rainfall from Atlantic weather systems - in the form of frontal rainfall. These weather systems usually move from west to east across the UK and as they do so the amount of rainfall they deposit reduces. This is because the mountains in the north and west of the UK cause lots of the rainfall to fall in those locations as the clouds are too 'heavy' to move over the higher ground - this is known as orographically enhanced or relief rainfall. Of course, frontal and orographic rainfall are not the only rainfall mechanisms, but they are the most common.
