Temperature maps

Temperature maps show the distribution (fields) of temperatures over a wide area. meteoblue uses a palette of predetermined colours to distinguish the different zones and to maintain a reference base for the user. You can combine the temperature maps with sea level pressure, wind animation and the graticule by activating the different options in the lower right corner with one click.

The daily temperature maps generally include maximum, minimum and hourly temperatures. The maxima and minima are always valid for the date indicated.

The air temperature is by default displayed in °C, and you have the possibility to change the unit on the left side by clicking on the unit label at the top of the colour scale.

Temperature (observation)

Temperature (observation)

The coloured numbers on these maps show temperature measurements of weather stations for the indicated time. The colours are based on the standard temperature palette. These maps can also be combined with other maps: For instance, adding isotherms allows you to compare actual temperatures with forecast temperatures. More: see temperature

Temperature

Surface temperature (2m)

These maps show the temperature at a specific altitude (e.g. 2m above ground) at the indicated time with colours as specified in the map legend. By adding other plots like streamlines for example, you will have the possibility to see where (warm or cold) air masses come from, for instance. More: see temperature

Temperature in different altitudes

Temperature can be displayed in different altitudes as selected in the menu. The temperatures displayed correspond to the temperatures at the indicated altitude (on the top left hand side of the map).

Minimum/maximum temperature

Maximum temperature (last 48h)

These maps show maximum or minimum temperatures in the indicated time period (e.g. last 12h). Both are expressed in degrees Celsius (°C) or degrees Fahrenheit (°F) and are displayed with colours as indicated in the map legend. More: see temperature

Temperature amplitude

Temperature amplitude (last 24h)

These maps show the temperature amplitude that occurred within the last 24 hours. It is expressed in degrees Celsius (°C) or degrees Fahrenheit (°F) and is shown with colours as indicated in the map's legend. More: see temperature

Temperature change

Temperature change (last 24h)

These maps show the change in temperature in the last 24 hours. It is expressed in degrees Celsius (°C) or degrees Fahrenheit (°F). Positive and negative values are possible as indicated in the map's legend. More: see temperature

Equivalent potential

Equivalent potential (Theta-e)

These maps show the equivalent potential temperature (Theta-e), which is expressed in degrees Celsius (°C) or degrees Fahrenheit (°F). The colours correspond to the normal temperature palette and are described in the map's legend. More: see temperature

Wet-bulb potential

Wet-bulb potential (Theta-w)

These maps show the wet-bulb potential temperature (Theta-w), which is expressed in degrees Celsius (°C) or degrees Fahrenheit (°F). The colours correspond to the normal temperature palette and are described in the map's legend. More: see temperature

Freezing level height

Freezing level height

These maps show the altitude of the freezing level (zero-degree isotherm) in the free atmosphere, which is expressed in meters (m). More: see freezing level height
