The origins of the buoyancy force and the vertical perturbation pressure gradient force are reviewed. A discussion of parcel theory and its limitations follows. The quantitative determination of updraft velocity from environmental soundings is complicated by factors such as environmental heterogeneity, hydrometeor loading, freezing, entrainment, and vertical perturbation pressure gradients.
