Figure 1 (click for larger) is showing surface level air movement from weather GCM. The stuck cold air mass over North America is part of a lack of rotation of the polar air mass leading to a stuck Atlantic circulation bringing repeated storms to Northern Europe where the energy is from the ocean circa Caribbean but with a back feed from the coast of Africa. Around and around. The parallel red arrows are showing where cyclone and anti-cyclone meet, to the left there is a sharp merge of three flows, an unstable region, the shear point is where the St Jude’s day storm formed.

El Niño and La Niña Basics: Introduction to the Pacific Trade Winds

Watts Up With That?

England et al. (2014) Recent intensification of wind-driven circulation in the Pacific and the ongoing warming hiatus continues to receive attention, and with that attention comes basic questions for many people about trade winds. NBC News has an article by John Roach with the title Global Warming Pause? The Answer Is Blowing Into the Wind. And the team from RealClimate have agreed and disagreed with England et al. (2014) in their post Going with the wind. We’ve already discussed England et al. (2014) in the post here, and we’ll discuss that NBC News article and the RealClimate post in an upcoming one.

For this post, we’re going to concentrate on why the trade winds blow and why they’ve grown stronger in recent years. This is an “introduction to” post. It is not intended to confirm or contradict the findings of England et al. (2014). It is intended to illustrate…

ren: How did the polar vortex lock?

Tallbloke's Talkshop

Guest post from commenter ‘ren’ a friend from Poland with a strong interest in meteorology and some interesting ideas on the relationship between solar activity, cosmic rays, ozone levels and stratospheric pressure systems.

How did the polar vortex lock?
by ‘ren’ on 23-2-2014

In October 2013 there was a decrease in solar activity, as evidenced by the growth of cosmic rays at that time.

This decline resulted in a short-term rise in temperature in the stratosphere, the ozone zone.

As a result, the temperature rise was halted polar vortex, which is picking up speed in the winter. View.

It is interesting that the inhibition occurred only over eastern Siberia, which indicates that over the area changes in solar activity caused the greatest effect. Smaller solar activity means an increase of ionizing radiation over the Arctic Circle, which in turn affects the reactions taking place in the area of ​​the…

Recent Caribbean earthquakes spark concern

The Extinction Protocol

Barbados 6.5
February 2014CARIBBEANTwo earthquakes greater than 5.0 have rocked the Caribbean in the last week and concerns have been growing for a major tremor in the region. On Tuesday, Feb. 18, a strong 6.5-magnitude quake occurred about 100 miles north-northeast of Bridgetown, Barbados. According to Dr. Joan Latchman, the Director of the Seismic Research Unit of the University of the West Indies, it was the strongest tremor since 1980 in the area. Three days later, on Feb. 21, a 5.1-magnitude seismic event occurred near Aruba. While both of these quakes did not cause much damage, they are a reminder that the Caribbean remains a very active seismic zone, prone to earthquakes at anytime. Earthquakes are common in the Caribbean, but most are less than 3.0 on the Richter Scale. The two recent, stronger rumbles have rekindled memories of highly destructive earthquakes over the past few hundred years…
