meteogram

thumb|An example meteogram showing plots of temperature, pressure, precipitation, cloud cover, wind speed and wind direction A meteogram, also known as a meteorogram, is a graphical presentation of one or more meteorological variables with respect to time, whether observed or forecast, for a particular location. Where forecast data is used, the meteogram will typically be generated directly from a weather forecasting model based on the longitude, latitude and elevation of the location, but it can also be corrected by a meteorologist. Where a meteogram is used to display historical weather observations, this will typically be for a specific weather station.

In the meteogram, time is plotted along the X axis, while the values of the different weather parameters are plotted along the Y axis. The most common weather parameters in a meteogram are precipitation, temperature, air pressure, cloud cover, wind speed and wind direction, such as in this example meteogram provided as part of a weather forecast by yr.no. In this example, wind speed and wind direction are conveniently presented in the form of wind barbs, precipitation is represented in column format, while temperature and air pressure are represented as lines. Cloud cover is represented in a layered format, providing an indication of the amount of cloud at different heights in the atmosphere.
