This is probably a stupid question but I am having trouble getting my head
round what happens when two big HP's link. For example the MO chart for
Sunday has the large HP west of Ireland and the displaced Siberian High
nearly linking. Both have similar central pressures. Both obviously have a
clockwise flow, sort of going in opposite directions not far from the
merging area. If they did link where would the centre of the new HP be and
why? Meteorologists amongst you probably think this is obvious but I am
interested as there has been conjecture that this might happen and would be
wintry.

Dave. 6.6C, wet and thoroughly horrible, especially after yesterday's great
winter day.
