We tend to concentrate on the performance of very low barometric
pressure as a cause of hurricanes. There is another problem that has
received little attention in the press. Just as there are extremes in
low pressure areas which produce the conditions for cyclonic storms
including hurricanes, there are also extremes of high pressure areas
which have a significant effect on the weather. In the current example
of Florence, the hurricane is expected to stall and even move to the
south rather than follow the normal path of hurricanes into the Atlantic
where they can cool off relatively harmlessly. Why is this? We are
increasingly seeing stationary high pressure systems (clockwise
rotation) that push the low pressure areas to the south. This tends to
stall them and produce a lot of rain and flooding. That is a very real
danger for Florence, while the storm is expected to reach land over
North Carolina, the rainfall and flooding is expected to extend down to
South Carolina and Georgia.

When you pump additional energy into a system, you can reasonably expect
extreme reactions.

LOL!

What's your theory on what's causing the high pressure areas? You never
really stated what it was. "Global Warming" causes high pressure?
Really? Are you a trained meteorologist?
