At the start of this month Met Eireann forecaster Joanna Donnelly said she could see an anti-cyclone moving from the Portuguese islands further south in the Atlantic and she dubbed this system the "Azores High
Weatherman Derek Brockway tweeted: "Some signs it will turn cooler and fresher for a while early July but the Azores high

Later on Friday, the fleet faced a key decision on how to deal with the Azores High
. Most of the weather models showed that a northern course would pay in terms of more wind, but the southern route was more direct to Lisbon.
The oscillation, which is a difference in air pressure between the Iceland Low and the Azores High
, can affect weather across the U.S.
The prevailing circulation here if western (latitude) air-mass transport, conditioned by interaction of the Azores high
and the Icelandic depression.
Much like the Azores High
or the Siberian High which you might have heard of, Saudi Arabia also has a dominant high pressure system.
This would push all the low pressure systems (unsettled weather) on a path towards Iceland and allow the normally reliable Azores high
pressure cells (settled weather) to reach the UK.
PWS said this summer could break records because the El Nino weather phenomenon, which warms the Pacific Ocean, combined with the effects of the Atlantic jet stream weather pattern and the Azores high
The weather in Scotland is highly influenced by a semi-permanent pressure system called the Icelandic Low, and that in Morocco by another called the Azores High
Bahrain Team Pindar faced windy conditions as Thompson made his way towards the Azores High
, which is now just 400 miles ahead of him.
With the failure of the Azores high
