Condensation and partial pressure change as a major cause of airflow: Experimental evidence
The dominant model of atmospheric circulation is based on the notion that hot air rises, creating horizontal winds. A second major driver has been proposed [1] in the biotic pump theory (BPT), by which intense condensation is the prime cause of surface winds from ocean to land. Critics of the BPT ar...

La teoría de la bomba biótica (BPT) [1] propone un segundo mecanismo, en la cual la condensación intensa sea la causa primaria de los vientos superficiales. Los críticos de la BPT discuten que cualquier movimiento del aire resultando de la condensación sea isotrópico [2]. Este artículo explora la física de la condensación de vapor de agua bajo condiciones atmosféricas livianas, utilizando una estructura experimental diseñada para tal fin. Los datos demuestran una correlación altamente significativa (R2 0.96, p valor 0.001) entre los flujos de aire observados y los cambios en la presión parcial resultante de la condensación.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).

A second major driver has been proposed [1] in the biotic pump theory (BPT), by which intense condensation is the prime cause of surface winds from ocean to land. Critics of the BPT argue that air movement resulting from condensation is isotropic [2]. This paper explores the physics of water condensation under mild atmospheric conditions, within a purpose-designed square-section 4.8m-tall closed-system structure. The data show a highly significant correlation (R2 0.96, p value 0.001) between observed airflows and partial pressure changes from condensation. The assumption that condensation of water vapour is always isotropic is therefore incorrect.
