develop

Weather
front Explanation
Cold front If a cold front moves in, the
weather remains changeable
and there are often rain show-
ers 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 min-
imally. 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.
