SAHARAN DUST IN EUROPE, MARCH 2022

From Peter Engelmann, March 19, 2022

Saharan Dust in Europe appeared in the second week of March 2022. This is not an unusual weather pattern in spring. This year, however, there was a very high concentration of Saharan Dust in the atmosphere. It was even labelled a “dust bomb”. It led to an unparalleled otherworldly if not apocalyptic scenery in many places around Europe. The phenomenon was accompanied by rain in some places. This rain is called blood rain, due to the reddish colour. The blood rain was a bad omen in former times. The blood rain was a harbinger of the Black Death in Middle Ages or war and other apocalyptic events. The term blood rain is associated also with other phenomenas in nature due to bacteria or other where rain is red coloured.

The Saharan Dust in March was not only impressing because of the yellow-orange tinted skies but because of the vast dimension. The dust came from Marokko, entered Spain, reached Germany and was seen in UK too.

A map provided by French Meteorologist Guillaume Suchet shows the fast range of the saharan dust plume which reached even Norway and Sweden:

Saharian Dust Over The Alps

This is not very often. In Bavaria the phenomenon was extraordinarily intense in the afternoon of March 15. It created “Martian Skies” for hours. Around noon the sky was cloudy but colors were still normal. It was a milky grey sky. Later the day, in the early afternoon hours, the sky became intensely orange and red. The webcams on certain mountains showed that the orange sky was nearly everywhere. The sight remained good. There was no mist. But the clouds became thicker and thicker. Between 3.00pm and 5.00.pm it became really dark. It was necessary to turn on the lights inside. Such a darkness had never occurred before. It contributed much to the “apocalyptic mood” of the day. Later the sky returned slowly to “normal mood” again. There was some rain. Cars, roofs, everything was covered by a thick layer of reddish dust.

The camera looks to the south-east. At the horizon there is still less concentration of dust particles. The thick yellowish clouds were coming from the west.

The pictures reveal even more unusual things which happened during this weather pattern. Colors weren’t changed here. The sky had indeed these reddish colors. Dust removal effect in photoshop however shows some unusual patterns inside this clouds. There is a detailed structure in the clouds which wasn’t so clear to the pure eye. There is nothing added or manipulated here. It seems like an unusual coincidence between saharan dust and a certain cloud weather pattern.

Rayleigh scattering phenomenon

There is another interesting phenomenon here. The saharan dust creates the so-called Rayleigh scattering phenomenon. Met Office meteorologist Dan Stroud explained the phenomenon: “The dust in the atmosphere causes the light to be more refracted, so you get the dominance of the red and orange tinges of the spectrum”. Rayleigh scattering is “the dispersion of electromagnetic radiation by particles that have a radius less than approximately 1/10 the wavelength of the radiation” The dust in the air originated from the storm Celia and swept as a plume over Europe.

Rayleigh scattering during saharan dust in the sky is very interesting from a photographic standpoint. It creates different lighting conditions as on a normal sunny or cloudy idea. It is more like a studio light, a diffuse light not so much a directed light. You see no shadows. In film and photography this soft light coming from different directions is often a desired effect. It’s also a effect used in the artificial sky atmosphere of the Unreal Engine software where the Rayleigh scattering can be “regulated”.

The Rayleigh scattering effect might be a reason why some people are having an uneasy feeling during such weather events. It has an apocalyptic feel because in natural conditions. It feels somehow “wrong”.

Rayleigh scattering is also present on normal weather conditions and is responsible for the blue sky on a normal day. However the effect is much different as during a saharan dust event. During the appearance of the saharan dust cloud there are many additional particles in the atmosphere.

When the darker clouds arrived there were unparalleled cloud structures.

The air was not either cold nor war. Of course, the quality of the air was bad and that bad quality lasted long. After the saharan dust an unusual high pressure system begun to form over Northern Europe. That’s bad news since the continent urgently need more rain.

Winter Storm Nadia, January 30, 2022

End of January shores at the Northern Sea and stretches in different countries were hit by winter storm Nadia. This was a low pressure system which changed weather condition in Germany after a quiet period with high pressure. Most of the days there were low hanging mist, some snowfall and lots of sun in the Alps. The weather change is not unusual for this time of the year. Winter Storm Nadia did serious damage on the island Langeroog, Hamburg and Berlin. In Langeroog the sand of a shore was swept away and what was left was some kind of newborn cliff.

Windy Sunday Morning: Fast moving clouds, waves and snow on the hills in the background

In Southern Germany there was a windy night between January 29 and January 30. The wind calmed down a bit in the morning of Sunday, January 30. There were moderate winds at the Lake Ammersee. Temperatures were up a bit after some cold days. The snow remained in the higher places of Upper Bavaria. As often there were interesting atmospheres and cloud patterns during that stormy winter day. Even the wind was only moderate on the ground, the clouds were moving fast. It was a quick change of conditions with sunlight and overcast sky. The air was very clear This is always a condition after a storm and very useful for taking pictures or taking videos.

The winter times and morning hours are also a good time for pictures and videos, since the sun is not heigh up in the sky. Therefore there are interesting cloud colours and a crisp blue sky between the fast moving clouds. It is good to avoid walks through forest even after a frontline or a storm has passed. Open places like meadows, hills or the shoreline of a lake are safer places to capture some pictures.

Driftwood after the storm night

The shoreline on the Eastside of the lake Ammersee, the second biggest lake of the so-called “FĂĽnf-Seen-Land” south of Munich is a popular spot for photographers. It is close to the nature reserve “Ammersee West” and there is a sense of wilderness there. There is always driftwood and whole trees scattered around. If the branches or trees last longer in the water they can turn into sculptures. Nature is an artist here.

Thus it was the idea to take a stroll at the shore of lake Ammersee near that nature reserve and take some pics with the fast moving clouds on Sunday morning. It was only a quieter moment between two storm systems. The wind was taking up again on Monday, January 31. Temperatures dropped again and snow as falling. Series of storms are not unusual for this period of the year. However, we see now unusual extremes at any time of the years in some parts of the world. Whereas winter storm Nadia was more or less a “normal” storm, the U.S. was hit by extreme winter conditions. the same time.

After a cloudy morning there were more and more blue skies. In January the winter sky has that special blue color. After the front had passed the day before it was dry til the next day. Wind and waves changing the appearance of this special shore all the time.

MAGIC LATE AUTUMN IN THE LECH VALLEY

Photographers, hikers and outdoor enthusiasts love autumn. The colours of leaves turn from green (Summer, August) to yellow (September), orange and red (end of autumn) The breathtaking imaginary in New England created the name Indian Summer. In Europe the name is Golden October. It is indeed some times the season with golden colours. It’s the trees but also the burning skies during sunset when the sun illuminates the clouds. The fall season has indeed many faces. It is worth to dig deeper into whats happening during autumn. Because there are so many shades. Landscape photographers can discover a tremendous variety.

The Best Autumn Experience

It depends on one side on the time of the year and on the other side where you look for an autumn experience. As said before colours turn all the time: From the first yellow leaves in September often into more orange and red end of October/early November. Any sort of tree has its own color in autumn. And any forest has a different set of colours. Beech tree forests like in Northern Germany create a more orange imaginary, as the alpine forests have a unique set of colours. There are fine colours here and these colours are changing a lot. It’s always good to check weather forecasts a lot if you plan a stay in the alps to enjoy autumn or if you plan to do some landscape photography.

In some years the colours of autumn last til November or even longer. Then the mountains forests show a huge variety of compositions of autumn colours. However weather and climate in the alpine region is harsh. In some years winter begins earlier. Or a storm ends the time of autumn colours abruptly. Thus, it is important not to miss the right moment to take pictures or do a video about the autumn season in the mountains.

The second thing is to find the right place. Of course if it comes to watch the autumn colours decidous forests are a first choice. However a larch wood in autumn is also great. The needles are getting a orange color which looks great. What about a riparian forest?

A riparian forest has its own set of plants and trees. However, original riparian forests are rare. There is often flood measures or other regulations of the rivers in Europe. There are only a few real original river landscapes in middle Europe. One of them is the Lechtal in Germany and Austria. The Lech was once a wild river coming from high up in the mountains and ends in the river Danube. There is not so much left from this once intimidating river. However the Lechtal in Austria between Vorarlberg, Austria and the German town Füssen in the Allgäu region is still a unique wilderness in many places. It is a place of incredible beauty. A place for adventures, long hikes and a place to learn about nature. In this wild river region there are still impressing riparian forest. They change all the time. During autumn they present a unique scenery.

The Treetop Walk In Ziegelwies, Austrian-German Border, FĂĽssen

Thus the river lech region around FĂĽssen and the Lechtal in Austria is a great place to see these riparian forests. But what’s even more fascinating is to see that riparian forests from above and to learn more about it. The Ziegelwies Baumwipfelpfad offers an unique perspective. It is some meters above ground and allows to be at the same level as the tree tops. The entry is directly near the German-Austrian Border. A parking space is near the street between FĂĽssen and Reutte in Tyrolia. It offers fantastic oportunities for landscape photography.

Here is a view from the entry area of the treetop walk. The riverbank of the river lech is in the background.

The treetop walk on the left side allows many scenic views and is an unique experience. At the highest point there is a platform above the forest.

The forest on the other side of the river Lech is a healthy mixture of many different tree species. The river changes the landscape all the time. Flooding kills some trees but also creates new spaces.

The treetop way has a length of 480 metres and a height of 21 metres. The entrance fee is 5 Euros. There is an exhibition and a playground for children. Furthermore there is riparian forest trail below. The well-known “Lechfall” is a famous photo-location and sightseeing location. There are walks to the famous Neuschwanstein Castle, the Schwansee, a geo-path and a mountain forest trail with certain stations where you can learn more about the forest and the region.

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.
