from which a tornado can develop. Torna-
does are also known as twisters.
-cyclone:
storm cells from which a tornadic storm
can develop
-hailstorm
-the likelihood of a hailstorm

Legend: weather fronts
Weather
frontExplanation
Cold front
(blue line with
blue triangles)If a cold front moves in, the
weather remains changeable
and there are often rain
showers and thunderstorms. The air temperature decrea-
ses.
Warm front
(red line with
red semi-cir-
cles)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 trian-
gles)The weather front moves
minimally. The weather
remains changeable in this
area.
Occlusion
(purple line
with purple
semi-circles
and triangles)When the faster cold front
catches up and joins the
warm front ahead of it, an
occluded front is formed. The
weather remains changeable
and rainy within an occlu-
sion.
Displaying storm tracking information:
XActivate the TropicalStormTrackingdis-
play level (Ypage 166).
If weather data is available, the weather map
will then display storm tracking information.
Example: in the middle of the map you can see
the current position of the tropical low-pres-
sure area (cyclone). To the right of this a solid
line shows the previous path with positions
and times. The forecast for the direction of
propagation is shown by a dotted line with
positions and times.
You can find out detailed information on a
cyclone in the Storm Guide (Ypage 169).
A tropical storm is separated into different cat-
egories according to the location at which it
develops.
