Weather front Explanation
Cold front
(blue line with blue trian-
gles)
If a cold front moves in, the weather remains changeable and
there are often rain showers and thunderstorms. The air tem-
perature decreases.
Warm front
(red line with red semi-
circles)
A warm front may cause more prolonged steady rain, more cloud
cover and a slow rise in temperature.
Stationary front
(red and blue line with red
semi-circles and blue tri-
angles)
The weather front moves minimally. The weather remains
changeable in this area.
Occlusion
(purple line with purple
semi-circles and trian-
gles)
An occlusion arises when the faster cold front catches up and
joins the warm front ahead of it. The weather remains change-
able and rainy within an occlusion.
