Despite rain and fog: autumn in Germany is far too warm.
A warm water bubble in the Pacific causes a real heat wave - with global consequences.
So far,
autumn has
not been quite as golden
in Germany
.
With
rain and wind
, the temperatures went steeply downhill.
The weekend holds a mild one
A surprise ready, but sometimes also brings a stiff breeze at night.
The mild temperature is due to a dangerous weather phenomenon called
"blob"
.
Offenbach - In
October 2020
all signs were pointing to
instability
: Heavy precipitation, strong temperature changes, as well as
storm surges
on the
Baltic Sea
and
foehn storms
in the
Alps
were part of the weather program *.
October was too warm, too wet and unusually cloudy.
This is
now
reported by the
German Weather Service
after initial evaluations of the measurement results from its around
2000 measuring stations
.
So October has not shown itself at its best - does
November
make up for it and become a golden month?
Or can winter sports fans look forward to it?
Germany weather: Lots of sun on Saturday - then comes the change
With a south-westerly current, very mild air first reaches
Germany
.
According to the
DWD
, the interim high influence
prevails
on Saturday and is
noticeable
with a lot of
sunshine
, before one then has to
reckon
with the outflows of a
low moving
into the
North Sea
on Sunday night
.
This causes stiff, stormy gusts at the North Sea and at higher altitudes above 1000 meters.
The
DWD
does
not
rule
out some
violent storms
* and
even
expects
some
gale-force gusts *
for the
Harz Mountains
at night
.
Along and south of the
Danube
there is again very
dense fog
and visibility below 150 meters.
Until at least Wednesday, November starts the same way October ended.
At the sea and in the peaks there are
stormy to hurricane-like gusts
, while otherwise it is changeable and there are also showers.
South of the Danube
and on the
Upper Rhine it
remains largely dry and even clears up from time to time.
The maximum values are between 16 degrees Celsius on the
Baltic Sea
and up to 23 degrees Celsius in the
southwest
- so it is unusually mild.
Where the sometimes thick
(high) fog
dissipates, the
sun
comes
through
at the end of the week
.

The
weather experts also
expect November to be unusually mild.
A climate phenomenon on the coast of North America is probably responsible for this.
In the
Northeast Pacific
, a “blob” - a giant warm water bubble - has formed that is heating the oceans worldwide.
Researchers assume devastating damage to
ecosystems
as a result of advancing
global warming
.
According to a study published in the journal
Advances in Atmospheric Sciences
, the
oceans were
warmer than ever last year.
The temperature was 0.075 degrees Celsius higher than the long-term average.
“Blob” phenomenon: Satellite images show the dangerous extent of the warm water bubble
"The heat that has
landed
in the
world's oceans
over the past 25 years is
equivalent to the explosion of 3.6 billion Hiroshima atomic bombs," explains
atmospheric physicist Lijing Cheng
from the
Chinese Academy of Scientists
.
This has consequences: Large
warm water
areas are constantly forming
.
The best-known
hot water bubble
is the "
blob
", which has now
formed
several times off the
North American coast
.
The first “
blob
” caused water to be heated up to seven degrees Celsius in places from 2013 to 2016.
In 2018, the second "
blob
"
stretched
from California to the Gulf of Alaska and made temperatures around three degrees Celsius warmer, as
reported by
weather.com
.
The new #MarineHeatwave off the #PacificCoast is reminiscent of the early stages of the 2014–2016 “blob” that devastated marine life.

The “blob”: warm water bubble causes mass deaths
With an area of 9.8 million square kilometers, the
new “
blob
” breaks the previous record of 1980, as it is already as big as
Alaska
and heats the water by four degrees Celsius.
Immense accumulations of
hot water
like this cause great damage, as they cost
the lives of
millions of
marine animals
- from plankton and fish to sea birds.
The
climatologist Kevin Trenberth
reported in U
S National Center for Atmospheric Research
estimates that about whales by looking for new hiking trails on which they became entangled in fishing lines and drowned.
The
"
blobs
"
also
caused
a devastating
poisonous algae bloom
.
They ate shellfish and could no longer be sold by fishermen worldwide.
Due to
climate change
,
water temperatures
are rising
worldwide and trigger
warm phases
like these more often than ever, which in turn creates drastic problems.
"Destructive heat waves there were in 2003 in the Mediterranean, 2011. Western Australia, 2013. Northern Australia -. The list goes on," the environmental magazine writes
YaleEnvironment 360.
Was there in the 1980s still 25 heat wave days per year, there were 2010 already 55 days .
Another study shows that even with vigorous
climate protection measures,
the
oceans will
remain in an “almost permanent heatwave state” until 2100.

Not good news for
marine life
, as they all have
temperature limits
.
In warmer water they need more oxygen, which is becoming increasingly scarce there.
A single
heat wave
can not only kill living things, but also
affect
ecosystems for decades
.
Corals are also bleaching and kelp - useful, large brown algae that form kelp forests in the shallow sea - are dying, as the 2010/2011 heatwave hit the
Australian coast *
showed.
After almost ten years, they
still haven't recovered the
kelp forests
in 2020.
Hurricanes are favored by the "blob"
Weather.com also
reports that the
heat waves in the sea
promote another dangerous climate phenomenon, triggering tropical storms that intensify hurricanes *.
"Michael" caused a lot of destruction in 2018, researchers now attribute this to a
heat wave
that preceded him and
abnormally heated
the marine area off
Florida
.
The
hot water bubbles
can
Trenberth
According
hurricane
also trigger directly: Such a hot spot was in 2017 in the Gulf of Mexico also Hurricane "Harvey" develop, which claimed 82 lives and wreaking damage in the amount of 108 billion dollars.
