The thunder is caused by the sudden expansion of the air in the immediate surroundings of the lightning – it can reach temperatures of up to 30,000 degrees Celsius and is only a few centimeters thick! This discharge can occur both by a lightning strike to the ground or to another cloud. The friction of the water molecules in the cloud creates a high electrical voltage, which is balanced by the discharge of a lightning bolt. The driving engines for a thunderstorm are high solar radiation, water evaporation, and the resulting formation of a cloud (more on cloud formation here). This allows you to locate lightning “live” and in “real-time” yourself. Due to the different arrival times (in the range of milliseconds) of the electromagnetic wave, precise conclusions can be drawn about the impact location and the strength of the lightning.
This wave arrives at different radar stations at the speed of light. The measuring technique of the lightning radar makes the decisive contribution here: Each lightning/lightning strike emits an electromagnetic wave that propagates over hundreds of kilometers. The great advantage of our lightning strike map is that thunderstorms and lightning are displayed with a very short delay. Here is what you need to know about thunderstorms and the lightning radar! This way you can see exactly how the thunderstorm has developed over the last hours and minutes and infer where the thunderstorm will move on to. To display the temporal course and direction of the lightning front, simply click on the cursor symbol. Each of these flashes signals a single lightning strike. On the lightning map, you can also see small flashes of lightning, which are indicated by a short, white flash. Blue or green color indicates a relatively weak thunderstorm or weak precipitation.Ĭaution is advised in case of yellow, orange, red, and especially purple coloring:Ī lightning front of this type involves a clear risk of severe weather. The strength of the thunderstorm is measured with the help of precipitation as also with our storm radar. The lightning map shows you current thunderstorms in color.

Tracking the current lightning front – How to read the lightning map: Depending on the strength, the precipitation is displayed in blue (weak precipitation), green, yellow, orange (moderate precipitation), red, or purple (very heavy precipitation). Thunderstorms and lightning strikes are indicated by a lightning symbol.
