London smog is Found in
1 Summer, during day time
2 Summer, during morning time
3 Winter, during morning time
4 Winter, during day time
Explanation:
London-type smog or classical smog is caused mainly by air pollution due to the combustion of coal and emission of sulphur dioxide and dust. It is formed in the morning of winter season especially.
