Extreme Weather In Southern Germany June 2021

Peter Engelmann, July 3, 2021

2021: A cold spring with temperatures in May below average. Luckily there was lot of rain in parts of Germany after a drought since 2018 in some areas which damaged trees and raised serious concerns for example about the future of the water balance and water supply. In June a heat wave followed. However unlike in previous years there were no long lasting high pressure systems. The weather situation wasn’t so far stable for a long time. The heat wave ended with some extreme weather events. And again, we had situations for example in South-West-Germany or in Landshut, lower Bavaria, which were unprecedented. There are a lot of discussions now going on if this is climate-change related or if it is another rare weather pattern.

Things began to change in Bavaria June 20, 2021. The days before had been mostly dry except first thunderstorms in the Southwest and in the Alps. On June 20 there were some rumble and not so intense lightning in the region west of lake Ammersee. As usual there are huge local differences: There were soon stronger thunderstorm whereas a few kilometres apart from that place nothing or little happened. That’s very usual and always challenges weather forecasters.

The next days there was a much different weather situation: In the late afternoon or evening real strong thunderstorms occurred. Rotating supercell storms were also reported in the Southern Germany. Even more extreme weather happened in France where an air mass boundary created havoc. In France huge clusters of thunderstorms formed repeatedly and moved to Belgium and North-West Germany.

The extreme weather with strong thunderstorms, flash-floods, even extreme hail with enormous hailstones and masses of hail lasted for a couple of days. The reason: The air mass boundary moved only slowly in Europe. It worked like a machine charging up the atmosphere and creating new thunderstorms. A time-lapse video from June 21, 2021 late afternoon gives you some idea how quickly the storms formed:

It was interesting that there were very different types of thunderstorms. The location southwest of the Ammersee experience short-lived thunderstorms, a thunderstorm which arrived very quickly as the next day there was slow movement and plenty of time to take pictures. In the night there was also one of the “stroboscope”-like thunderstorms, where you hear not much loud thunder but you see an incredible light show with high rates of flashes. There were both thunderstorms without wind and thunderstorms with very strong wind.

The thunderstorm on June 24 created some great lightning:

The storm below occurred June 28, 2021 and brought intense lightning. However it was completely different as the “strobe-storm” the night before before. The lightning was also better visible. After one of the storms there was also a thick mist around sunset. Later the mist vanished and another thunderstorm with strong lightning occurred. The stronger storms came mostly from the Alps.

Flash Floods and Super Cell Storms

Finally there was an exchange of air mass. The hot humid air was replaced by colder air. June 29 was the climax of the series of thunderstorms in Germany: In Bavaria, a super-cell coming from Baden-Württemberg, intensified and brought an incredibly flash flood in Landshut Lower Bavaria. The days before a deadly tornado happened in the Czech republic. The video shows the aftermath of the big storm on June 29 which was accompanied by very strong winds.

Here is also an interesting thing for photographers and videographers: Usually most people are interested to catch a storm coming to them or before it happens. But there is a lot of possibilities to get interesting moods and pictures when the storm passed. The video belows shows what was going on in the atmosphere after this huge thunderstorm on June 29.

Thunderstorms before Sunset

In Upper Bavaria weather changed Sunday, June 28. Along the Allgäu Mountains, intense rainfall began in the afternoon. Thunderstorms with hail occurred in the south-east of Bavaria. The hailstorm pilots near Chiemsee started four times theses days. Clouds and rain created a magical atmosphere around Weissensee not far from the famous Neuschwanstein castle.

Three days later an impressing thunderstorm happened in the early evening hours in South-Bavaria. It was before sunset. Thus there were interesting effects with a colored sky. There were some intense local rainshowers and the weather lasted for more days.

On July 2 a supercell-storm devastated an area around Murnau, which is not far from Garmisch Partenkirchen. Witnesses reported that there was both hail and a flashflood rain at the same time. They could not remember a similar phenomenon happened before. Within 15 minutes streets were flooded and cows had to be rescued from a farm.

Later the week the weather calmed down. This kind of weather is very typical for the season in Bavaria. There is always a change between warm summer days and rain except the last years when a drought happened. Most of the severe storms in Germany happen in July. In 1984 an unparalleled hailstorm led to incredible destruction in Bavaria’s capital Munich.

Intense supercell-storms, hail and flash floods can, however, occur any time between May and September. In June 2019 a hailstorm led to a lot of destruction in the Northern-Ammersee region. In some years there were storms with flooding in May. Storms happen also in August, usually in September heavy thunderstorms are not so often because the days are getting shorter. There is less energy from the sunlight to generate these type of storms however there are weather patterns which could also lead to strong storms in October. In September 2017 lightning hit the Munich Octoberfest.

Thunderstorms with devastating hail happen more often in the south-east of Upper Bavaria rather than in the Allgäu. Usually, the storms develop over the hills and mountains in the West and move to the East. A squadron of Hailstorm pilots, “Hagelflieger” from Vogtareuth protects the area around lake Chiemsee efficiently and gather important scientific information.

Landscape photography in spring: Many shades of green

The end of winter and the beginning of spring is always a special time. Nature awakes. It’s a great time for photographers too. After a long time where we see mostly brown and grey in the landscape, there is an explosion of green and yellow. However, you have to act fast to capture the many shades of green.

The beginning of spring is not the same every year. Sometimes it happens earlier but in some years when it’s cold and there is still snow spring comes late. Usually, you see the first plants already in February on the Northern Hemisphere: Snowdrop plants and later on cowslips appear even there is still snow. The Yellow forsythia is a herald of spring. But it’s still a long way. However often in April, everything happens very fast. Meadows become green and yellow again. In some areas, the Meadows turn into an intense yellow when the dandelion is blooming.

The motives are easy to capture. You don’t need expensive gear. However, it is great if you have a camera which shoots in raw mode. There are much more opportunities to play around with the shades of green later in post-production.

The different phases of the spring season

The most interesting part happens when the trees are sprouting. Only for a short time, we see what is called the “fresh green” in nature. It’s the time and weeks after spring awakening. Later in May, we see mostly a darker green in gardens and forests. The foliage doesn’t show so many different shades of green then. Thus, landscape photographers have to be quick and be ready when the right moment comes.

Cowlips are among the plants which appear early in spring.
Fruit tree blossom in April. The most trees are still without leaves.
The nights are still cold. It looks like spring is still far away but within days there will be graduated shades of radiant yeallow and green. Spring awakening is already in full progress.

In the Northern Hemisphere the growing season begins in the South as Italy or Greece and arrives later in Northern countries. Farmers know a lot about the dynamics in nature and there are scientific parameters too. The most important parameter is the grassland temperature sum (GTM). The sum is based on an equation. If the sum is 200 Celsius the farm work begins.

If you want to learn about the beginning of the growing season check with your local weather services website. There is often information about the progress of spring there. If you are used to read weather data there are also specialized weather websites for farmers etc, for example https://www.agweb.com/weather in the US.

Weather, of course, plays a crucial role. You will see fast changes in nature after a period of rain in the spring. These are often the best moments to shoot pictures.

Sunlight is good to capture the many shades of green in Spring. However, a rainy day can be very interesting too since there are a lot of different moods. Morning time and the time before sunset is often the best time for shooting pictures of blooming trees.

The graduated shades of radiant green

Pictures of fresh green mostly don’t need a lot of post-production. However, some filters and development can help to create stronger differences between the shades of green.

End of April: Often the best time to capture the graduated shades of green. Use the luminance panel in photoshop or lightroom to add details to the many shades of green. Be careful with saturation because the colours are already very strong.
Colors of foliage change very quickly in spring. The “fresh green” lasts only for a short ime.

One week later there is a different shade of green
It’t the first days when trees are spouting you see these radiant colors.
Birch trees have very distinct colors.
A rainy day can very interesting for landscape photography
First Week Of May: Colors are darker now. It still looks great but its already a completely different mood.

Where to shoot

It’s good to know where you can find the “many shades of green” in Spring. The best thing is to have a plan where to go long before the season begins. Generally, you might want to look for a forest with a huge variety of trees, a mixed forest. If you don’t have nature reserves or these type of forest around you can do also great pictures in landscape gardens, English-style. Mountain forests with many fir trees can also be interesting but there is, of course, less variety of colours there. Look also for meadows which are very natural and where there is a variety of flowers and plants. The pictures above were taken in Germany, Upper Bavaria between the river Lech and the lake Ammersee.

Magnificient Skies And Brilliant Colors Like Never Before

April 6, 2020

The Corona crisis is an unparalleled situation and there is no bright side to this. It would have been wonderful if we could have made observations about changes in the atmosphere, weather and perhaps climate change under different circumstances. Nevertheless, it appears there is a unique chance for a potentially positive change in the future. For some days we see for the time how a sky would look like with little or no pollution in the air.

When the crisis reached Europe and the rest of the world air traffic declined. In Germany, there was a lockdown after middle of march. There are fewer planes operating. We now see an immediate effect: In Middle Europe, there was a high-pressure weather pattern in March and is still lasting in April. The air became clear and cold with some dust in the morning. However, there was a new quality in the atmosphere.

Over the last years there was a lot of pollution in the atmosphere due to increasing air traffic. The contrails never disappeared. The sky always looked dirty. It looked liked as the atmosphere couldn’t take any more. It was too much pollution. The result was often a strange sky with unusual clouds which presumably inspired the “Chemtrail Conspiracy theory”.

Now we have a chance to see how a sky without pollution and air-plane traffic looks like. It is not only like looking through a window which was cleaned up after a long time. We see different colors. There is some otherworldliness too it. It is like entering a different realm, a world remembered from childhood days for the elder generation.

The absence of pollution and air traffic doesn’t only mean clear skies and great colors. It looks like a healthier world and might have also effects for weather and climate. Hopefully there is a chance for scientists to do research even the circumstances appear difficult.

Air traffic created an artificial cloud layer on many days. Thus, there was less cooling in the night. The pollution added to global warming. We will see how weather patterns develop if there is little or now pollution in the upper atmosphere.

There is another interesting question: We don’t know very much about cloud development and how the increased air traffic has changed the development of clouds as rain clouds. Over the last years climate change led to many droughts. Scientists say this is mostly because of the CO2 emission but perhaps there are other factors. If we see more clouds now like we had a long time ago it could mean that air traffic had a much bigger impact than previously assumed.
