'Moderate to Strong' La Nina coming

Recommended Posts

Everyone talks about weather but no one does anything about it.  So they say.  But weather impacts our lives, our mood.. our food..everything.  In the short run this La Nina might have more affect on our lives then the coming election that is over shadowing it. 

 

The World Meteorological Org (WMO) predicts a moderate to strong La Nina event coming from the Pacific Ocean.  On its way and set to last through the first quarter of 2021, likely bringing a mixed bag to the worlds weather.  While generally a cooling phenomena, it will..

"A La Niña develops when strong winds blow the warm surface waters of the Pacific away from South America and towards Indonesia.

In their place, colder waters from deep in the ocean come up to the surface.

This event leads to significant weather changes in different parts of the world.

If a really strong La Niña event were to occur, research suggests that the UK and Northern Europe might experience a very wet winter.

Normally La Niña means countries like Indonesia and Australia can get much more rain than usual, and a more active monsoon occurs in southeast Asia.

There are likely to be more storms in Canada and the northern US, often leading to snowy conditions.

Southern US states can be hit by drought at the same time.

The last time that a strong event developed was in 2010-2011.

The WMO says there is a now around a 90% chance of tropical Pacific sea temperatures remaining at La Niña levels for the rest of this year.

There is a 55% chance of the conditions persisting through the first quarter of next year.

While a La Niña event normally exerts a cooling influence on the world, this is unlikely to make too much of a difference to 2020.

"La Niña typically has a cooling effect on global temperatures, but this is more than offset by the heat trapped in our atmosphere by greenhouse gases," said Prof Petteri Taalas, from the WMO.

"Therefore, 2020 remains on track to be one of the warmest years on record and 2016-2020 is expected to be the warmest five-year period on record," he said

"La Niña years now are warmer even than years with strong El Niño events of the past."

It drives the big pump which alternates the east  and north coast of Australia and the inland  between  wet and dry  years ; droughts and extensive wetlands .  When  LaNina comes the interior  of many places turns into giant wetlands and the birds flock in .

 

 

 

 

 

Its started its effect here already ; heavy rains , in some parts floods. In  some harvest areas its impacted on harvest . Vast areas of the inland  have turned into wetlands and attracted huge numbers of birds .  This time last year  it was  all drought , extra dry and started burning . So we probably will not have a fire season , or a dangerous one .  We will have a wet season and hot and humid weather . And floods , and stinky mud  and leeches and a raging river .    Just like the old days  :)

I am hoping for a  more moderate one than a strong one .
