wind_stream:

The direction of the arrow is in downwind direction. The color shows the wind intensity in Bft according to the following legend:

There is often a question araising about the alining of the stream lines of the wind_stream tiles:
At the border of the tiles the wind direction and speed is matching, but not the line.
That´s because each tile is calculated separatly (the software doesn´t know where the lines are ending at the neighbour tile).
There is nothing wrong, all values are correct for each position.
The only solution would be to generate the whole layer as one picture and then cut it into the small tiles. This would take to much cpu and memory resources (The server generates about 2000000 tiles every 6 hours).

At the other tiles the principle of tile generation is the same, but if you draw a line e.g. at a certain pressure, the lines are matching from tile to tile, as long as all calculations are correct.

wind_barb:

Visualization of the average wind intensity in 10m height in knot (kn).
The direction of the barb is in upwind direction. The color shows the wind intensity in kn according to the following legend:

precipitation:

Visualization of the amount of precipitation in mm/m2h.

The displayed amount of precipitation had changed since the 1st of August 2016:

now:
For the timesteps 0h and 6h the average amount of precipitation in liter per hour for the next 6 hours will be displayed.
For the timesteps 12h, 24h, 36h, 48h, 60h and 72h the average amount of precipitation in liter per hour for the next 12 hours will be displayed.
Now it´s easier to compare the precipitation values of the different timesteps as they are all displayed in liter per hour.

before:
For the timesteps 5, 7 und 9 the amount of precipitation is accumulated for the next 6h,
for the timesteps 11, 15, 19, 23 und 27 the amount of precipitation is accumulated for the next 12h.

There is often a question araising about the alining of the stream lines of the sea_surface_current tiles:
At the border of the tiles the current direction and speed is matching, but not the line.
That´s because each tile is calculated separatly (the software doesn´t know where the lines are ending at the neighbour tile).
There is nothing wrong, all values are correct for each position.
The only solution would be to generate the whole layer as one picture and then cut it into the small tiles. This would take to much cpu and memory resources (The server generates about 2000000 tiles every 6 hours).

At the other tiles the principle of tile generation is the same, but if you draw a line e.g. at a certain pressure, the lines are matching from tile to tile, as long as all calculations are correct.

sea_surface_temperature:

Visualization of the sea surface temperature in degree Celsius (°C). The color of the lines indicates the temperature of the sea surface in °C according to the following legend:
