Viennese weather science: Hydrogen balloon takes off and sends data!

Döbling, Österreich - In Vienna, a fascinating weather phenomenon causes a stir. Today, on July 8, 2025, a hydrogen balloon with a diameter of almost one and a half meters lifts itself into the air. This special balloon, which rises at a speed of about five meters per second, becomes a small point on the horizon within just half a minute. It will finally burst at a height of 35 kilometers and extend to a diameter of about seven meters due to the lower air pressure. The balloon and its attached transmitter collect important information about temperature and humidity, which are important for the weather stations across Europe. The weather station on the Hohen Warte in Vienna is also integrated into this impressive event, which takes place twice a day. This reports The standard .

The balloon is not only a technology miracle, but also symbolizes the state -of -the -art meteorology that is operated in Vienna and beyond. The data collected flow into the corresponding weather forecasts and contribute to the safety and the prediction of weather extremes. Weather stations that work like that on the high wait are connected to a network that promotes meteorological exchange in Europe.

A look at Riga

In order to better classify the Viennese weather, it is worth taking a look at Riga. In the Latvian capital, the temperatures hardly fall over 21.7 ° C, while the average daily temperature drops to 9.6 ° C. The nights are significantly cooler with an average of 1.4 ° C and low values ​​of -9.9 ° C. This ensures that Riga is often affected by temperatures below freezing in winter - for five months. According to Klimattabelle.de spend the letters a year with rain and see only about five hours of sun a day.

Especially in the Baltic States, the air humidity with an average of 79.4 % is quite high. This makes the Riga summer a challenge despite occasional warmth, while the cool months strongly shape the image of the city climate.

The role of weather monitoring in Europe

But what about the weather monitoring in Europe in general? The RCC Node-CM-the Regional Climate Center on Climate Monitoring-plays an important role here. This is commissioned by the World Organization for Meteorology (WMO) and delivers daily cards for temperature and precipitation for Europe and the Middle East. Daily cards are based on the interpolated station values ​​of synoptic stations and are created as part of the European Flood Awareness System (EFAS) of the EU. This shows how important coordinated climate data are for the prediction of extreme weather events. More on this can be found on the website of German Weather Service .

In summary, one can say that weather monitoring plays a crucial role not only in Vienna, but across Europe. With a hydrogen balloon over the city, it once again realizes how important precise data is for the future of our weather forecasts. Whether in the Viennese heights or the sea winds via Riga - for a good knack for our weather!
