Weather
front Explanation
Cold front If a cold front moves in, the
weather remains changeable
and there are often rain
showers and thunderstorms.
The air temperature
decreases. Warm front This can mean longer periods
of rain and can lead to an
increase in cloud cover and a
slow increase in temperature.
Stationary
front The weather front moves
minimally. The weather
remains changeable in this
area. Occlusion This occurs when a faster cold
front reaches an advancing
warm front and combines
with it. The weather remains
changeable and rainy within
an occlusion.
