What was no doubt correct in Halley's theory was that solar heating creates upward motion of equatorial air, and air mass from neighboring latitudes must flow in to replace the risen air mass.
O que era correcto sen lugar a dúbidas na teoría de Halley era que a calor solar creaba un movemento ascendente do aire ecuatorial, e a masa de aire das latitudes veciñas debía fluír para substituír a masa de aire ascendente.
