MAGIC ATMOSPHERE ABOVE THE CLOUDS: HIGH-FOG IN THE ALPS

Ideas for landscape photography in the colder season

Autumn is just around the corner. This means the days are getting shorter. The colours change. In some regions like the Alps there is more often high fog, a weather pattern where hills and peaks sometimes are above the clouds.

Fog is interesting for photographers in many ways. It adds mood and atmosphere to the pictures. Fog is useful in landscape pictures to add structure. Of course if the fog is very strong and there is nothing but a white wall it is an obstacle.

Misty days occur mostly in autumn, spring and winter. The change of temperature and moisture creates fog. There are a lot of interesting phenomena connected with fog. Sometimes it is a thin veil above a meadow. On other occasions there are thick layers of fog and the fog lasts the whole days. Sometime the fog is moving, sometimes not. In time-lapse videos the movement of fog is somehow similar to water. The shrouds of mists “float” along mountain peaks.

Since misty air is colder the fog can “fall” like a water-fall for example when fog floats over a ridge into a valley. Fog begins to form often before sunset and lasts in the morning hours. When the sun shines the mist often disappears during the day. However in river valleys like the Danube valley the mist can last much longer. It is often significantly colder in these day.

Fog is more often in regions with wetter soil like bog or wet meadows. It happens in summer too. Shrouds of mist appear after hail showers or after thunderstorms too. In July the first mornings with fog are early harbingers of the changing season. As the days become shorter and the nights getting colder misty mornings happen more often.

Its often hard to say if the fog lifts or disappears during the day. There are many different weather conditions. Fog can be also dangerous when it suddenly forms and the visibility turns to near zero. Drivers are surprised and can’t see a thing. Since conditions on a foggy day can always change quickly it is good for drivers to slow down particularly on motorways and highways when a layer of fog appears.

If the weather is cold fog can lead to hoar frost. Ice crystals form and surround twigs and trees. This a particularly interesting phenomenon.

There is one form of fog which is great for photographers if they are in a regions with hills or mountains. Mostly in autumn there are days with high fog. This happens when a thermal inversion occurs. This means you have low ground temperatures and a layer of higher temperatures above that prevent the convection currents. These convection currents usually mix in the atmosphere. You can think of a thermal inversion like a saucepan lid. It keeps the colder moist air layer with fog from rising. This happens a lot in basins and during periods of high pressure weather when there is not much wind.

The video below was taken in the morning of February 28, 2021 with a Canon 5d Mark2. The time-lapse shows the movement of the shrouds of mist above the hillside between the Hohen Peissenberg and the peaks of the Bavarian mountains. There is a quick change in visibility and a change in lighting condition. For video it is good to go into manual mode and fix aperture before shooting.

At the border between the layer of cold air and the warm air on top the cold air layer there are very interesting effects which are useful for pictures and videos. The challenge is to predict where that border is: Where does the blue sky break through the thick layer of mist? And when does it happen? Actually this is a lot of try and error.

Knowing some good places is “money in the bank”. You might want to get to a hill or mountain which is easily accessible and high enough that you can get above the cold air layer with mist. In Germany, Bavaria the Hohen Peissenberg with its famous old weather observatory is a good spot. Mostly because there is a road to the top of this mountain. The top of the Hohen Peissenberg has an elevation of 987 metres. However on some days the layer of mist will be above your heads and you need to find a higher mountain.

The pictures were taken on a spring day in 2021. That day there was a typical thermal inversion. In the morning the Hohen Peissenberg mountain was in the middle of a thick layer of high fog. But in the following hours the sun broke through and there was a very interesting scenery with fast changing moods and impressions.

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.

Thunderstorm in the early evening hours of June 20:

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.

Thunderstorm approaching June 24, 2021

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:

Lightning June 24, 2021

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.

Landschaftfotografie im Frühjar: Viele Schattierungen von Grün

Das Ende des Winters und der Beginn des Frühlings sind immer eine besondere Zeit. Die Natur erwacht. Es ist auch für Fotografen eine gute Zeit. Nach einer langen Zeit, in der Braun und Grau die Landschaft dominieren, gibt es eine Explosion von Grün und Geld. Jedoch muss man schnell sein, um die vielen verschiedenen Grüntöne mit der Kamera zu erwischen.

Der Beginn des Frühjahrs ist nicht immer derselbe jedes Jahr. In manchen Jahren beginnt der Frühling früher und in in manchen Jahren liegt lange Schnee und es ist noch kalt. Üblicherweise sieht man die ersten Pflanzen bereits im Februar in der nördlichen Hemisphäre. Schneeglöckchen und Schlüsselblumen etwas später tauchen schon auf, selbst wenn noch Schnee liegt. Die leuchtend gelben Forsythien kündigen den eigentlichen Frühling an. Aber es ist immer noch ein langer Weg. Jedoch passiert oft dann meist sehr viel in kurzer Zeit meist im April. Die Wiesen werden grün und gelb. In manchen Gegenden, wo viel Löwenzahn wächst, nehmen die Wiesen sogar ein intensives Gelb an.

Diese Motive sind leicht einzufangen. Man braucht keine teure Ausrüstung. Jedoch ist eine Kamera mit raw-.Mode von großem Vorteil. Es gibt dann einfach viel mehr gestalterische Möglichkeiten mit den Grüntönen in der Nachbearbeitung zu spielen.

Die verschiedenen Phasen des Frühjahrs

Der interessanteste Teil des Frühjahrs beginnt, wenn die Bäume austreiben. Nur für ein paar Tage sieht man dieses sprichwörtliche “frische Grün” in der Natur. Es ist meist die Zeit in den Wochen nach Frühlingsanfang. Später, im Mai, sieht man im Garten und im Wald dunklere Grüntöne. Das Laub zeigt nun nicht mehr so viele Grünschattierungen. Deshalb müssen Landschaftsfotografen schnell sein, um den richtigen Augenblick zu erwischen.

Schlüsselblumen erscheinen früh im Jahr.
Obstbaumblüte im April. Die meisten Bäume haben noch keine Blätter.
Die Nächte sind immer noch kalt. Es sieht so aus, als ob der Frühling noch ganz weit weg wäre, dabei wird es schon in ein paar Tagen viele Schattierungen von Grün und Gelb geben. Der Frühling ist in Wahrheit bereits voll im Gange..

In der nördlichen Hemisphäre beginnt die Vegetationsperiode im Süden, in Italien und Griechenland und erreicht später die nördlichen Länder. Landwirte wissen eine Menge über die Dynamik in der Natur, und es gibt auch wissenschaftliche Messgrößen. Die wichtigste Größe ist die Grassland-Temperatur-Summe (GTM). Diese Summe beruht auf einer Gleichung. Wenn die Summe (aufsummierte Werte) 200 Grad Celsius ergibt, beginnt, die Arbeit auf den Feldern.

Wenn man mehr erfahren möchte über die Vegetationsperiode, empfiehlt sich ein Blick auf die örtliche Wetterwebseiten. Dort gibt es oft Informationen über den Frühlingsfortschritt. Geübte Nutzer können Wetterdaten auf speziellen Agrar-meteorologischen Seiten auswerten, zum Beispiel in den USA auf: https://www.agweb.com/weather

Selbstverständlich spielt das Wetter eine zentrale Rolle. Man sieht sehr schnelle Veränderungen in der Natur, wenn es zum Beispiel länger geregnet hat. Das sind oft die besten Augenblicke zum Fotografieren.

Sonnenlicht ist gut, um die verschiedenen Grüntöne im Frühjahr einzufangen. Jedoch kann auch ein Regentag mit seinen verschiedenen Stimmungen sehr interessant sein. Der Morgen und die Zeit vor Sonnenuntergang sind die beste Zeit für blühende Bäume und spriesende Äste zum Aufnehmen.

Die verschiedenen Stufen leuchtenden Grüns

Fotos von frischem Grün brauchen meist nicht viel Nachbearbeitung. Jedoch können bestimmte Filter und Entwicklungsschritte helfen, die Unterschiede zwischen den Schattierungen hervorzuheben.

Ende April ist oft die beste Zeit für Grünschattierungen. Mit dem luminance panel im photoshop oder in lightroom kann man Details hervorheben. Vorsicht mit der Sättigung, denn die Farben sind schon sehr stark.
Die Laubfarben ändern sich sehr rasch im Frühjahr. Das “frische Grün” gibt es nur für ganz kurze Zeit.

EIne Woche später trifft man einen ganz anderen Grünton an.
An den ersten Frühjahrstagen, wenn die Bäume austreiben, gibt es diese leuchtenden Farben.
Die Birken haben dann eine ganz besondere Farbe.
Ein Regentag kann sehr interessant sein für Landschaftsfotos.
Die erste Maiwoche: Die Farben sind jetzt dunkler. Es sieht immer noch toll aus, aber die Stimmung ist eine andere.

Wo sollte man Bilder machen?

Es ist gut zu wissen, wo man im Frühjahr die vielen Grüntöne findet. Die beste Idee dafür ist meist ein Plan, lange bevor der Frühling beginnt. Generell wird man nach Wäldern mit vielen verschiedenen Laubbaumarten Ausschau halten. Falls man keine Naturreservate oder derartige Wälder in der Umgebung hat, sind Landschaftsgärten, vor allem “englische Gärten” sehr geeignet. Bergwälder mit ihren Fichten und Tannen können auch interessant sein, aber dort gibt es in der Regel weniger Farbauswahl. Man müsste auch dort nach naturbelassenen Wäldern Ausschau halten. Sehr interessant sind naturbelassene Wiesen mit einer großen Auswahl an Pflanzen. Die hier gezeigten Bilder wurden in Deutschland zwischen dem Ammersee und dem Lech aufgenommen.
