Abstract

The pressure perturbation associated with a convective cell has been measured with an aircraft, at one level about 1500 m below cloud top. Agreement is found with Barnes' (1969) experimental data and with the results of the Wilhelmson's (1974) three-dimensional model of a convective cloud in a shared environment. The efficiency of the “pressure shield” against entrainment is examined.
