Meteograms
An easy way to look at a time series of meteorological data at a particular location is by plotting this data in a "meteogram." In a meteogram, time progresses from left to right across the figure. One or more meteorological parameters can be plotted, either as line graphs, bar graphs or even symbols. Using a meteogram, one can get a feel of how conditions will change and evolve at a stationary point.
Keep in mind that like all the other model forecast information provided by us, these data are "as is". They are straight from the computer models, no interpretation, corrections, or other objective or subjective changes have been made. These are not the "official" forecasts, though in most cases they should resemble those rather closely.
Forecast meteograms are given for eight locations in Belgium, representing areas with high activity of soaring and balloon flights. The following meteorological parameters are represented for each of these locations:
- Temperature and dewpoint in degrees Celsius. (line graph)
- Wind speed (line graph) with speed scale on the left Y-axis
- Dynamic and convective rain rate (mm/hr) with scale on right Y-axis
- Dynamic and convective snow rate (mm/hr) with scale on right Y-axis
The meteograms are updated twice daily (09:30 and 21:30 Z) and give a forecast of the above parameters for the next 24 hours.
