6-14 days meteogram
You can find the 6-14 days meteogram in the tab "Charts & Tools" under 14 Days (detail).
The 6-14 days meteogram summarizes the hourly forecasts starting from forecast day 6 until day 14. This meteogram gives a good overview of the probability of the expected weather condition.
The meteogram is made from different forecast model runs ("ensemble"), which show the possible development of the weather. The most probable condition is the mean, the extremes show the possible range of developments.
The first diagram shows the range of possible temperatures for the next 6 to 14 days. The bold curve corresponds to the mean while the thin curves correspond to the possible extremes.
The second diagram displays the range of precipitation amounts likely to occur. The black lines represent the minimum to the maximum possible precipitation amounts, while the blue bars represent the average amount.
On the third diagram, you can see the range of possible percentage of cloud cover. The thin curves represent the minimum and maximum possible cloud coverage, while the bold curve correspond to the mean. The background colours (blue to grey) help to visualize different levels of cloud cover. The yellow background displays the day duration. You can well see the difference between night and day on the sample diagram on the bottom of this page.
The last diagram shows the range of possible wind speed, with the mean in the middle. The wind direction and speed are shown by the wind barbs.
