If there is a High Pressure System in front of a hurricane, how does it affect the hurricane's direction?

Answer 1

Good question. What you have posed is a rather typical situation during the summer as a tropical cyclone approaches the US. If the high is overland its leading edge is generally a weak cold front. The storm barrels into the high becoming an extratropical low pressure center which subsequently moves along the front. If the high pressure center is at mid latitudes and over the ocean such as is the case with the so-called Bermuda High, the storm continues on a westerly course steered by the flow about this high and the wind structure in the easterly flow in which it is embedded. I hope this helps a little. As you might guess it is indeed a little more complicated than this but I have given you a fairly good answer on this.

Answer 2

The isobars around a high steer weather systems around the anticyclone, so the anticyclone (high pressure system) acts as a block. So in the northern hemisphere, if you're in the Azores and there's a high over you, as there often is, any low pressure system approaching from the west, the usual direction, will be deflected to the north of you. That's why temperate zone places in both hemispheres get more rain in winter. In the north Atlantic and Europe, the highs are further north in summer than winter, so in summer the lows which bring rain are pushed to the north of you and you get drier weather.

Answer 3

It would cause the storm to go to the other direction and possibly die away
