Explanation of the layers on the
weather map
RMenu item Radar Map
Displays the rain radar as a colored area in all
map scales. For an explanation of the colors,
see the legend (
Ypage 172).
RMenu item Storm Characteristics
Displays the characteristics of a storm in all
map scales:
-tornadic storm:
storm cell with strong winds (super cell),
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
RStorm watch areas
Shows areas for which storm advisories have
been issued (red areas). It is shown in map
scales 50 mi (50 km), 200 mi (200 km) and
500 mi (500 km).
RMenu itemAtmospheric Pressure
Shows the position of high and low-pressure
areas (H, L), weather fronts and isobars It is
shown in map scales 200 mi (200 km) and
500 mi (500 km).
RMenu itemTropical Storm Tracking
Shows the direction and speed of propagation
(track) of a tropical storm in all map scales
with information on times and intensity.
RMenu itemWinds
shows the wind direction and wind speed in
map scale of 5 mi (5 km).
Sample displays of weather data in the
map
Displaying the rain radar:
XActivate the Radar Mapdisplay level
(Ypage 170).
The rain radar image is then displayed if
weather data is available.
iYou can call up the legend for the precipita-
tion radar (Ypage 172).
The transparency of the precipitation radar
map display level can be adjusted in five
stages.
Displaying storm characteristics:
XActivate the Storm Characteristicsdis-
play level (Ypage 170).
If weather data is available, the weather map
will then display the storm characteristics.
You can call up the legend for storms
(
Ypage 172).
The following information on a storm cell is
displayed (if available):
Rcharacteristics of the storm cell
Rdate and time of observation (time stamp)
Rdirectional movement speed and path
Propagation speed: the speed at which the
storm cell is advancing.

Displaying weather fronts:
XActivate theAtmosphericPressuredisplay
level (Ypage 170).
If weather data is available, the weather map
will then display the weather fronts.
The example shows the position of high and
low-pressure areas (H, L), weather fronts and
isobars. Isobars are lines that show where the
air pressure is the same.
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 170).
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 173).
A tropical storm is separated into different cat-
egories according to the location at which it
develops.
