How does the atmospheric circulation system explain the u. k.’s mild, cloudy and wet weather?

Because of its proximity to the Atlantic ocean and it latitude.

Explanation:

In the global atmospheric circulation, the UK is close to a low-pressure area where the Polar cell and Ferrel cell are meeting. This would account for a lot of clouds. This also means that wet Westerly prevailing winds blow in towards the UK, causing a lot of precipitation. However, the UK does not get the same cold extremes in the winter or hot extremes in the summer like some countries on the same latitude. This is due to the warm ocean current from the Gulf Stream. Water has a much higher specific heat capacity than land so it stays mild and helps the land around it to stay mild also.

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
