I'm not a science student. Please keep your answer simple and straightforward so your help can be appreciated to the fullest. Thanks. In Winter when there are clouds in the morning and have been there for some time during the night, it will result in more cold. Because earth has lost its much of its warmth to the atmosphere and which has escaped into upper layer of atmosphere. Is it correct? Would the same thing happen when it's summer? When hot air mixes with cold air, it results in fog. Suppose hot/warm air flows into a cold area, it will result in fog. Wouldn't it result in rise in temperature because cold has extracted some of the warmth of hot/warm air and on average the temperature of the mixture would be high now. Do I make sense?
