This atmospheric river of wind sits near the equator, acting as a breeding ground for the thunderstorms that can eventually organize into tropical systems. Hurricanes are heat engines, drawing their energy from warm sea surface temperatures, generally requiring waters above 26.
How the Coriolis Effect Blocks Hurricanes South
However, the ITCZ generally hugs the northern edge of the Amazon Basin, placing it north of the equator for most of the year. This is not an illusion born of infrequent observation; it is a consistent meteorological reality.
The science behind this protective buffer involves a delicate interplay of ocean temperatures, wind patterns, and the very physics that govern storm formation. Consequently, even if a disturbance were to form near the northern tip of South America, the physics required to fuel the storm’s intensification are largely absent.
How the Coriolis Effect Blocks Hurricanes South
As storms move westward from Africa or the Caribbean, they eventually encounter the coastline of northern South America. Imagine trying to spin a top while blowing hard on its side; the top will wobble and collapse.
