Bermuda high
The Bermuda High is an effective area of high pressure over the North Atlantic in the area of Bermuda . It is part of the subtropical high pressure belt that spans the earth at about 30 ° north latitude.
The Azores high is a very active high pressure cell in the North Atlantic, which has a significant influence on the weather in Europe, Africa and North America. In some years a very strong subtropical high pressure cell develops , which has its center further west near Bermuda and is therefore referred to as " Bermuda high" , especially by the North American weather service and in the literature .
In those years of pronounced high pressure cells over Bermuda, the east coast of the United States experiences a heat wave and severe drought , while a monsoonal air current is favored over the Gulf of Mexico . In Florida , the high prevents thunderstorms from occurring in autumn and winter, but when the high weakens in spring, the rainy season (May to September) follows , usually accompanied by afternoon thunderstorms.
The location of the Bermuda high also influences the formation and trajectory of tropical cyclones . The stronger the Bermuda high is, the further west it leads the cyclones to the Caribbean and the USA and thus decides, among many other factors, where, how quickly and how strongly such a hurricane hits the mainland.
