7.2 magnitude earthquake strikes northwest of Acapulco, Mexico

The Extinction Protocol

Mexico 7.2 April 18th
April 2014MEXICOA powerful magnitude-7.2 earthquake shook central and southern Mexico on Friday, sending panicked people into the streets, where broken windows and debris fell, but there were no early reports of major damage or casualties. The U.S. Geological Survey said it was centered northwest of the Pacific resort of Acapulco, where many Mexicans are vacationing for the Easter holiday. It was felt across at least a half-dozen states and Mexico’s capital, where it shook for at least 30 seconds. Around the region, there were reports of isolated and minor damage, such as fallen fences, trees and broken windows. Chilpancingo, capital of the southern state of Guerrero, where the quake was centered, reported a power outage, but service was restored after 15 minutes. In Acapulco, 59-year-old Enedina Ramirez Perez was having breakfast, enjoying the holiday with about 20 family members, when her hotel started to shake. “People…

In the 1970’s, The Polar Vortex Was Caused By Global Cooling.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

The claims that the Polar Vortex, that has brought the cold winter in the States and wet weather to Britain, is linked to global warming are based on the theory of a weaker jet stream. The idea is that,as the Arctic warms, the temperature differential between high and mid latitudes decreases. As the jet steam is powered by this differential, the theory goes, the jet stream is liable to turn from a powerful polar or zonal flow to a slower meridional one.

Just imagine a slow moving river, and think of how it meanders in comparison to a fast moving one. The theory sounds superficially attractive, until one realises that such events have occurred regularly in the past.

Back in 1975, C C Wallen, Head of the Special Environmental Applications Division of the World Meteorological Organization, had this to say about the consequences of the cooling trend…

Severe Rain, hailstorm kills 5 in Punjab, Pakistan

Earth Changing Extremities

Storm Alert

Intermittent downpour followed by hailstorm, lightening played havoc in various areas of Punjab as five people were killed and scores injured in rain-related incidents.
Five people, including a teen girl, were killed in separate roof collapse incidents and lightning in Lahore, Gujranwala and Sheikhupura.
Wind storms in various cities, including Sheikhupura, Gujranwala, Kasur, Multan, Hafizabad, Gujrat, Sialkot and Layyah uprooted the trees, destroying the signboards, roofs of huts besides adversely disrupting the power supply.
Several cities were plunged into darkness due to tripping of dozen of feeders of the Lahore Electric Supply Company (LESCO).
More than 50 people were reported injured across the province in separate mishaps.
The hailstorm destroyed the ripened wheat crop in various cities of central and southern Punjab rendering heavy losses to the growers.

Severe Hail, Dust storm kills 17 in Northern India

Earth Changing Extremities

Storm Alert

At least 16 people were killed while scores others were critically wounded after hail and dust storms struck India’s northern state of Uttar Pradesh, government sources said Friday.
 
The sources added that a three-year-old died after a wall of school collapsed.
Many houses, mostly built of thatch and mud were uprooted, due to gusty winds reaching up to 75 kmph.
 
Due to hail and dust storm, hundreds of trees were uprooted and obstructed the rail tracks causing disruption of rail services in the region.
 
The storm also affected the electricity in the Uttar Pradesh and plunged 1.5 million households into darkness.

Is there a ‘shape’ to atmospheric circulation during low solar periods?

Based on a comment over at Weather Action

I’ve been looking into the 76/77 N hemisphere winter as well. Steven Goddard flagged up the similarities with this past winter & how the shape of the polar vortex was like theshape of the Laurentide ice sheet which sat over NAmerica during the Younger Dryas (including Alaska being ice free). Interestingly there was a tongue of sea extending this year off the coast of Labrador & Newfoundland. The winter that followed in 77/78 was notable indeed. I’m gathering more detail for a post, but it’s made me wonder is this the ‘shape’ of lower solar activity?

Piers Corbyn replied

Your+Steve Goddard’s point about the shape of that great Laurentide ice sheet which sat over N America in ‘the Younger Dryas’ period is very important. Question; was cold distribution in Maunder and Dalton similar or not?

The Maunder period will be difficult to infer due to the sparse records on both sides of the Atlantic but a fair degree of work has been done by the likes of Lamb. Things do improve by the Dalton onwards. This is the start of a few posts to investigate a possible shape

of low solar activity, that is a change in the shape of the upper air circulation.

“The late Prof HH Lamb, a world renowned climatologist, investigated the impact of the Little Ice Age on Scotland for part of his book Climate History and the Modern World. He wrote of arctic ice expanding further south and of reports of Inuit people arriving on Orkney between 1690 and 1728. One was said to have paddled down the River Don in Aberdeen. Snow remained all year round on the tops of mountains, including the Cairngorms…With weather patterns disrupted, fierce were winds battered the land.”

This period was also characterized by an anomalous winter atmospheric circulation over the circum-Atlantic region in the form of a tri-pole pattern.

Reconstructions of winter sea-level pressure (SLP) indicate that over Europe an anomalous low was found over the Balkan area and an anomalous high just south of Iceland (Luterbacher et al.,
2002). Over eastern North America, somewhat east of the Hudson bay, an anomalous low was found extending into the subtropics (Lamb and Johnson, 1959; van der Schrier and Barkmeijer, 2005). This latter low deepens the existing trough in SLP over the Newfoundland- Labrador area.
