I don't remember ever seeing it but can a warm high such as the azores
high become and cold high if it is displaced for long enough? If it happened would it get stronger or weaken in the same way a low does when cold air goes all the way round. Some modells seem to be suggesting that the Atlantic High (Displaced Azorse high) will move north and combine with the Russian high as it moves west. Would mean that the high would become a cold high? |

It all depends how you look at it, and what you mean by warm and cold in
this context. All surface high pressure areas are the surface manifestation of a cold anomaly in the atmosphere above. In most cases this is at the top of the troposphere and in the lower stratosphere, but over a cold continental surface the lower troposphere can become cold enough to produce a surface high, even if there is relatively low pressure aloft. -- Bernard Burton Wokingham, Berkshire, UK.
