Anomalous Cold set to Ravage South America by early October + the Changing Jet Stream

“A particularly dry and cold winter” has negatively affected South American crop production. Lima for example, the capital of Peru, just suffered one of its “coldest winters in 50 years,” according to its National Service of Meteorology and Hydrology.

And even now, after South America’s meteorological Spring has sprung, the anomalous cold shows no signs of abating, no doubt causing further headaches for the continent’s hard-pressed farmers.

Temperature departures during the first few days of October are on course to be as much as 20C below the seasonal average. With the nations of Chile, Central/Northern Argentina, Uruguay, Southern Brazil, Paraguay, Bolivia and Peru being worst affected:

According to climatology expert Lourdes Menis Álvarez, “Peru’s winter of 2018 was one of the coldest in almost 50 years — however, the winter of 2019 has surpassed it in intensity.”

These types of cold winters were once common-place in Peru, explained Álvarez, but of late, strong El Niños have brought “long summers and warm winters” to the region.

The evidence suggest the tide is now turning, however.

Brief bursts of heat steal the headlines, but it’s the persistent cold that’s the real story of 2019 so far, and not just in South America either — North America just averaged it’s coldest Oct-May in recorded history, while much of Europe has been anomalously frigid all summer, save for two plumes of intense African heat — an occurrence made more likely during times of low solar activity-induced meridional (wavy) jet stream flows:

THE CHANGING JET STREAM

Studying the jet stream has long been an indicator of the weather to come.

And to study the jet stream attention must turn to the sun.

When solar activity is high, the band of meandering air flowing some 6 miles above our heads is tight, stable and follows somewhat of a straight path. But when solar activity is low, as it is now, the jet stream loses strength and its band of fast-moving air becomes wavy which, in the NH, has the effect of dragging Arctic air south to much lower latitudes than normal:

This mechanism fully explains why far-northern latitudes have been experiencing pockets of anomalous heat of late, while the lower-latitudes –where the majority of us human’s reside– have been dealing with record cold (particularly eastern Europe, central Canada and Western U.S.).

This is the reality we’re living — not some folkloric, CO2-induced eco-tastrophe (snap!).
