Weather Visualization With MetX

Met X Starting Screen

With weather maps, weather data can be made accessible to all. A simplified user interface combined with our weather API provides you with a powerful tool for visualizing weather events worldwide, at high-resolution and in real time.

Visualize Weather With Weather Maps

In a general sense, a weather map is a map that visualizes the weather conditions over a certain geographical area. The weather events depicted can be past, present or forecast for the future. From a meteorological point of view, a weather map shows the current state of the atmosphere over a larger area. A weather map can provide information about certain weather parameters, such as temperature, wind speed, wind direction or precipitation. The weather observations or expected changes in the state are drawn in symbolic form or coloured contours.

Use of Weather Maps

Weather maps can be used to visualize weather data. The maps show the current weather situation in real time, but can also be used to forecast the coming weather. Possible weather hazards are thus recognised at an early stage. Weather maps are a decision support system and primarily help to make better and faster decisions in a complex environment.

Weather maps can be used not only by everyone as weather forecast maps. They are mainly used by meteorologists in the media, in the energy sector, agricultural industry, automotive industry, and by aviators. Animations and visualizations are easy to interpret and consequently facilitate better and faster decisions. They show the big picture and how the weather is developing. As a result, risks can be recognised and minimized,processes optimized, and costs reduced.

Creation of a Weather Map

A weather map describes the weather at a given time with a lot of individual information. A weather map shows, for example, measured values for air temperature, air pressure, cloud cover, precipitation, wind direction, wind speed and the course of fronts. The values are entered as two-dimensional representations, isolines or in the form of symbols which are interpreted into a weather forecast

Ground Weather Map

A ground weather map is the better known of the weather maps. To create a ground map, as it is also called, air pressure readings must be taken from all weather stations, i.e. all measuring stations located on the ground, in the catchment area of the map. According to the position of the weather station, the information is entered into the map. Satellite and radar images are also used here for precise assessment.

In the next step, the highest and lowest air pressure values are marked on the map. "H" stands for an area of high pressure and "T" - "L" for "low" - indicates an area of low pressure. The distribution of these high and low pressure areas is shown on weather maps as so-called isobars, i.e. lines of equal air pressure.

High-Altitude Weather Maps

High-altitude weather maps supplement surface weather maps and show the pressure and flow field of the heights at the respective location. These data are determined using radiosondes and depicted in weather maps. These values are displayed as lines of equal pressure surface height, so-called isohypses, and can be identified by smoother fluctuations than in isobars.

A weather forecast can then be created that shows the weather situation to be expected. In addition to the experience of meteorologists, values from the past and current state of the atmosphere are taken into account by applying physical rules and comparing the measured values with model calculations.

Weather Map Symbols

More accurate weather maps contain additional information on weather events, such as temperature, wind, wind direction, cloud base, dew point, etc.. The values are inserted into the weather map according to the station model.

The station model describes the graphic representation of so-called station messages. These show numerous circles, lines with arrows, numbers and symbols. The messages from the measuring stations are displayed according to a specific system. In this way, a large amount of information can be displayed on a weather map in the most space-saving way possible. The position of the respective station model on the weather map marks the position of the weather station. To avoid overloading the map, however, only the most important stations and their data are included here.

Features of a Weather Map

Just a few details on a weather map provide information about the weather situation at a particular time. The most important values for assessing a weather situation are:

  • Isolines

  • Fronts

  • Pressure areas

  • Precipitation


Isolines are depicted on geographical, meteorological and other maps and are lines of the same weather condition.

On a weather map, values on isolines are the same at every location. These lines can be used to determine which regions have a similar atmospheric condition. In addition, it can be checked how temperature, air pressure, humidity and other values have changed. The measurements are taken repeatedly and help to keep weather maps up to date.

The best known isolines are isobars for equal air pressure, isohyets for equal precipitation quantity or isotherms for equal temperatures.


A front is considered a narrow boundary zone between two air masses. In this area, sudden changes in air pressure, temperature, humidity and wind can occur.

A distinction is made between types of front:

  • Warm front

  • Cold front

  • Occlusions

  • Stationary fronts

Pressure areas

Pressure areas are considered the most important features on weather maps and describe areas of high pressure and areas of lower pressure. These differences are caused by the different degrees of heating of the air masses, because the air pressure is not evenly distributed over the earth.

A low-pressure area is a region with relatively low air pressure. The lowest value is the center of the low pressure area. It is caused by a drop in pressure on the ground or by warm air rising above cold air. On a German-language weather map, an area with low air pressure is marked with a "T". In English-speaking countries, an "L" for Low is used for an area of low pressure.

A high-pressure area, on the other hand, is an area with high air pressure. The highest air pressure occurs in the center. On a German or English weather map, a high-pressure area is marked with an "H".

The weather map shows an area of high and low pressure


Precipitation is differentiated between solid, liquid and settled precipitation. The weather symbols used for this are often self-explanatory. The symbols show current events, such as cloud cover, or warn of potential weather hazards, such as storms, ice and snow. Often these phenomena are also indicated by coloured areas on weather maps.
