From the Flight Deck with Captain Doug: Bermuda High
Nov 01, 2019
A semi-permanent high-pressure system.
The Bermuda High sits just north of the Caribbean region but domi nates the weather southward.
Air moves clockwise and outward, spreading northeast and east winds throughout the Caribbean.
Pilots flying to the Caribbean land east into these winds, called trade winds or northeasterlies. Another dynamic of any high-pressure system is subsidence (slow sinking air) that hinders cloud develop ment and rain.
That 's why your vacation weather is usually a car bon copy of the day before. Sometimes a shower is thrown into the equation due to daytime heating.
