Observations of the convective boundary layer over southern England using an instrumented light aircraft and radio‐sondes enable its structure and development to be described for two periods of active, shallow convection. Budgeting is used to deduce the sensible heat flux as a function of height, showing a downward flux in the upper part of the boundary layer associated with entrainment of warmer air from above. For the two occasions studied results indicate that the entrained sensible heat flux is about 0·3 of the sensible heat flux at the ground. For one of the occasions a moisture budget was possible yielding a value of the mean latent heat flux at the ground.
