Fronts

COLD FRONTS
Cold fronts work like this, the cold air moves slowly toward the warm air, when the cold air reaches the warm air. The cold air pushes the warm air upward, by doing that the air with precipitation. Moves up into the dew point, and since there is so much precipitation the droplets form quickly and fall out of the cloud on to Earth.

WARM FRONTS
The warm front works like this, the warm air starts to move toward the cool air. the warm air slowly goes up above the cool air making the cool air warmer, and making a cloud with precipitation. The cool air soon disappears because the warm air takes over.

STATIONARY FRONTS
The warm air and cool air go head on, they start pushing and shoving each other. First the warm gets pushed a little then the cool air gets pushed a little. And all this pushing and shoving gets them no where, that's why it's called a stationary front. Also all this pushing and shoving starts to make a cloud in the middle, a rain cloud or snow or etc.

OCCLUDED FRONTS
There are two cool fronts with warm air in the middle, one of the cool airs start to move. While the other just stays still, when the other cool air starts to move, lets name the cool air moving CoolM. CoolM pushes the warm air that is in between CoolS and CoolM upward. The warm air splits in half and one goes to CoolM's side and the other to CoolS's side. CoolM and CoolS and the warm air start to make a cloud. The cloud rains, snows, hails, etc. on CoolS.
