EvalOcean of a Blocking High

From: Weatherlawyer (weathe...)

I once asked a respected scientist on uk.sci.weather for his data on the placement of Low Pressure systems. I had the idea he was discussing the formation of Blocking Highs. Which just goes to show how little I knew at the time. I never got any data from him, maybe he didn't trust me or more likely he was prevented for reasons...

I since learned that the Carburettor Effect of the gap between two continents: Asia and North America serves to fuel the Blocking Highs with what is called the Semi-Permanent Aleutian Low.

For reasons (again best known to science ; # ) Little is understood about how these things develop. The more discerning of us can watch for ourselves (if we wish) http://www.bom.gov.au/charts_data/IDY20001/current/mslp-precip/IDY20001.mslp-precip.006.png?1640476800
Top Left, 40 degrees East over Southern Africa an High 1015 millibars (centre 1027mb.) attracts a small Low 998 mb by Tuesday.

This complex causes the Larger Low 854 millibars, on the coast of Antarctica at 20 degrees East to expand meeting the High, mixing and causing an overall drop in temperature at that latitude in the Indian Ocean.
This Low Complex is now the size of Antarctica which, in winter, can only grow more powerful.

Fed by more rainfall in Africa and from the cyclone in the Gulf of Carpenteria, Australia the isobars begin to encircle Antarctica unimpeded by storms and a definite gap between pressure systems caused by the mixing of different air masses can be identified at a pressure of 992 millibars.

There is no such thing as Stable Weather, it is all simple suction processes of imbalance, leading to a development of very high pressure, very dry air over the centre of the continent 1080 millibars by Saturday. I suspect this sort of engineering is responsible for the development of earthquakes as such explosive Highs deflate.

We will have to wait and see
