Like much of Europe, Winterthur experienced hot weather during the summer of 2026. During heatwaves, however, nighttime temperatures are just as important as daytime temperatures. When the air stays warm throughout the night, people have fewer opportunities to recover from the heat of the day. To investigate nighttime temperatures in more detail, we measured four […]
During the Silvester fireworks in and around Zürich, many of you probably noticed that the air became foggy at some point. This can be explained by particles, emitted from the fireworks, accumulating in the boundary layer and acting as condensation nuclei for water droplets, which together with the air moisture and temperature led to fog […]
As part of the Atmospheric Physics and Applied Meteorology course for Aviation studies at ZHAW, we carry out a vertical sounding of the atmosphere during lab hours. A radiosonde is attached to a weather balloon which then ascends through the atmosphere, measuring temperature, moisture, pressure, altitude, and its location along the way. As the balloon […]
