Explanation
to the graphs
The map is clickable. All
the red spots contains time series of the weather for the next three days.
The date and time of day can be seen on the x-axes.
Wind
dir. at 10 m
Shows the wind direction
at 10 meters height above ground in degrees. The angle is the direction
where the wind comes from. Example: 0 and
360 degrees is from
north, 90 degrees is from east, 225 degrees from south-west, etc. Note
that if the wind is shifting a little from e.g. 359 degrees to 1 degree
(which both are from around north), the curve looks dis-continuous, but
it is not!
Windspeed
(m/s)
Shows the wind speed
at three different heights above ground (10, 80 and 800 meters height)
in m/s.
T in
Celsius
Shows the temperature
at three different heights above ground (2, 80 and 800 meters height) in
degrees Celsius.
MSL
pres. in hPa
Shows the Mean Sea
Level pressure in hPa (=mbar in the old days). 1013 hPa is the standard
pressure.
Prec.
in mm/1h
Shows the accumulated
precipitation in milimeters per 1 hour. The black curve is the total percipitation.
The blue curve is the part of the total precipitation which is convective
(so the difference between the black curve and the blue curve is the non-convective
precipitation, or statisform precipitation). The red curve is the part
of the total precipitation which stays at the ground as snow (not melting).
Pbl
height in m
Shows the height
in meters of the planetary boundary layer.
Ustar
in m/s
Shows the friction
velocity in m/s (important for the Pbl height).
Heat
flux in watt/m>2
Shows the surface
heat flux in watt per square meter ( important for the Pbl height).
Rel.
humidity at 80 m
Shows the relative
humidity at 80 meters above ground. When multiplied by 100 the figures
are in percent.
Cloud
cover
Shows the cloud
cover for both low clouds (black curve) and high clouds (red curve). When
multiplied by 100 the figures are in percent. The total cloud cover are
the maximum value of the two curves. 100% is total cloud cover. 0% is blue
