Dear colleagues We are on the way to the solstice where we’ll arrive in about a month: The sun’s declination is -19.6° now which is only 3.8° from the minimum of -23.4° on the day of solstice. This means that our days won’t get much shorter anymore / that the days on the southern hemisphere have almost reached the maximum and will start to get shorter in a month already... But this newsletter is rather a flashback on October which is closer to the equinox than to the solstice and therefore still shows a lot of light and colors!

It was (still is...) interesting to trace the autumnal turning of our trees. This beech for example had still green leaves in mid-October: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710147.jpg Then, within ten days, the color changed: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710256.jpg I would be glad to get some feedback to my comment to the front page picture http://www.seasonsandbiomes.net

I could join a fascinating excursion to the Morteratsch glacier in the Engadine. At first we took the cable car to Diavolezza from where you have an overwhelming view on the Pers and Morteratsch Glacier. We heard that the small Diavolezza glacier almost melted in the nineties but that it was saved by covering it with sheets. Later it was covered with artificial snow which made the glacier grow! Then the idea came up do the same with the big Morteratsch glacier: A study showed that about 1km2 must be covered with artificial snow to make it grow again. They said they would take the water from a new glacial lake that will form 200m higher up in the Pers glacier. This gives the water a high pressure that is needed for the new generation of snow gun that works without additional energy. Here are some pictures: (click on “next”) http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710201.jpg and http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710400.jpg In the second part of the excursion we visited an ice stupa test site in Morteratsch. There they plan to build ice stupas this winter. They take the water from a nearby mountain stream without using additional energy. Water supply for the ice stupas: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710200.jpg The project should help developing a safe and simple technique to build up ice stupas in mountainous regions all over the world where water will become rare soon when glaciers will have disappeared.

Four seasonal sounds: Come with me for a walk along the Vernela river (with snow on the banks): http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710134.jpg Around the lake the snow was still frozen at the surface as you can hear: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710138.jpg Except some disturbing noise I made at the beginning and at the end of the record you can “hear the silence” in this wonderful valley. Just turn the volume to the maximum and you won’t hear any technical noise: only the sound of the waters in this valley and some insects: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710175.jpg This is still snow of a last winter’s avalanche with quite a lot of meltwater coming out of it: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710176.jpg
Polar sea ice: View last month’s changes by clicking on “next” / “previous”: Arctic: the sea ice closed up towards Siberia but not yet towards Alaska http://www.seasonsandbiomes.net/view.php?img=simb00001/00001171029.jpg Antarctic: the existing polynya has grown and two additional have opened: http://www.seasonsandbiomes.net/view.php?img=simb00002/00002171029.jpg After the September 15th maximum there was a second maximum this year on October 11th/12th that was slightly higher than the first. Thereby the uncertainty concerning the date of the maximum is solved.

Although we are in late autumn now we can still observe different phenological stages, even some blossoms as this gentian: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710040.jpg this thistle: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710251.jpg or this cow parsley: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710254.jpg General autumn coloring of the leaves: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710146.jpg Many trees got wonderful colors in the calm October weather as this hornbeam tree: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710145.jpg ...or this oak tree: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710148.jpg Some birch trees were still partly green towards the end of October: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710221.jpg For any reason the larches didn’t turn to a bright yellow as they normally do. Some trees rather turned brown and dropped their needles. This tree showed green, yellow and brown needles at the same time: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710258.jpg I rarely saw “traditional” yellow larches in my region this autumn. Although it was much drier than in September we still had many different mushrooms: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710070.jpg and one week later: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710140.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710073.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710074.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710075.jpg and one week later: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710144.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710076.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710211.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710252.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710259.jpg On the yew trees you can easily observe the blossom buds for next year: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710141.jpg ...but also yew berries: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710071.jpg Here are some other fruits: of the spindle tree: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710143.jpg or of the bitter nightshade: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710250.jpg In my garden some tomatoes turned red towards the end of October only! http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710261.jpg Even our corn turned yellow in October (but most of it is chopped and ensiled here): http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710079.jpg

After a wet beginning...: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710072.jpg (again water poured out of meadows on slopes which was good because we have a lack of precipitation since 2016) ...
October brought golden autumn weather for almost two weeks and finally a cold end with the first frost after summer: http://www.seasonsandbiomes.net/dailymeans1710.jpg http://www.seasonsandbiomes.net/815weatherdetails.html
After a September mean temperature of 13°C, October 2017 was only slightly cooler with 10.8°C: http://www.seasonsandbiomes.net/temp1217.jpg
Hurricane Ophelia: In the latest twist from an unusually potent Atlantic hurricane season, a tropical storm is now headed for the shores of Ireland. Hurricane Ophelia probably won’t make it to the island as a true hurricane; it is more likely to evolve into an extratropical cyclone as it passes over cooler North Atlantic water. But either way, strong winds and heavy rain are expected to blow into the southwest coast of Ireland and over parts of the United Kingdom on October 16, 2017: https://earthobservatory.nasa.gov/NaturalHazards/view.php?id=91125&src=nha

A lot of wood was harvested in a nearby forest. I was surprised about the amount of wood they took out of this little area. One part was rather a monoculture and therefore ok to bring in more light: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710077.jpg The other part was a mixed forest with many species and a healthy undergrowth: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710078.jpg

This gall disappeared before the leaf fell off, others remain on the leaves even when it turns brown – I wonder whether the insect inside trigger the process: http://www.seasonsandbiomes.net/viewgallery.php?img=simb91709/917091709235.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710255.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710149.jpg http://www.seasonsandbiomes.net/viewgallery.php?img=simb91710/917101710257.jpg

As we – nature included – often slide into this time of the year arriving sometime after the solstice it might be worth a try to become aware of how conditions change now and how we and nature (phenology, seasonality) respond – wittingly or unwittingly – to these changes. Stay healthy and upbeat!
