More droughts and flooding are being predicted because the La Nina climate sample goes into its third consecutive winter – one thing often called a “triple dip”.
The UN’s World Meteorological Organisation (WMO) predicts it should final till not less than the top of the 12 months.
That means it should have spanned three consecutive northern winters for the primary time this century.
La Nina is the cooling of ocean floor temperatures coupled with winds and rainfall.
It tends to have the alternative impact to El Nino, which is the nice and cozy part of the so-called El Nino Southern Oscillation.
It was within the final six weeks that La Nina circumstances strengthened within the tropical Pacific, affecting temperatures and rain patterns and making drought and flooding worse in several components of the world.
According to the WMO’s El Nino/La Nina Update, the present La Nina – which started in September 2020 – is prone to proceed over the subsequent six months.
There is a 70% likelihood of that taking place between September and November, and a 55% likelihood between December and February.

“It is exceptional to have three consecutive years with a La Nina event,” stated WMO Secretary-General Petteri Taalas.
“Its cooling influence is temporarily slowing the rise in global temperatures – but it will not halt or reverse the long-term warming trend.”
A worsening drought within the Horn of Africa and southern South America bear the hallmarks of La Nina, Mr Taalas added, as does above-average rainfall in southeast Asia and Australasia.
“The new La Nina update unfortunately confirms regional climate projections that the devastating drought in the Horn of
Africa will worsen and affect millions of people,” he added.
