You've got it backwards! A warm front forms when a warm air mass moves into a region occupied by a cold air mass.

Here's why:

* Warm air is less dense than cold air. This means it rises over the colder air.

* As the warm air rises, it cools and condenses. This condensation often leads to clouds and precipitation.

* The boundary between the two air masses is called a front. In the case of a warm front, the warm air is gradually overtaking the cold air, causing a slow, steady rise in temperatures.

So, to summarize, warm fronts are associated with:

* Warm air moving into cold air

* Rising warm air

* Cloud formation and precipitation

* Gradual temperature increases
