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.
