A radiant blue sky, no clouds in sight, lush green meadows, the cheerful twittering of birds, and temperatures that bring beads of sweat to your brow: that’s summer!
This hottest time of year is so glorious – but if you think back to last summer, you probably remember a swimming trip where your fun was suddenly interrupted by a violent storm. Unfortunately, this kind of meteorological misfortune belongs to summer the way olives belong to Martinis. As it happens, it’s on especially humid days that the heavens crash the most. Why is that? Because storms are created when warm and cold streams of air meet. The warm air rises, forming clouds and heavy condensation. Then the atmosphere well and truly explodes and the tension between temperatures is released through rain, lightning and thunder – summer’s natural fireworks.
In the case of lightning, the heated air begins to glow in fractions of seconds and the flash stretches over kilometres. When it’s at its hottest – the temperature of lightning can reach up to 30,000 degrees – the air expands explosively, which we hear as thunder. The unmistakable rumble comes from sonic waves reflecting off the clouds and the surface of the earth. During a severe storm, up to 2000 bolts of lightning streak through the sky per hour. Most of them never reach the ground, instead they hurtle around up among the clouds.
Bathing suit, sunscreen and Knirps
This means that on humid summer days, it’s a good idea to add a Knirps umbrella to your bag along with the sunscreen and swimming gear. Knirps‘ handy umbrellas can easily fit in any beach bag, and they also come in countless stylish colours, patterns, and designs – so you can dance in the rain with style.
