Temperature and humidity fluctuations obtained from a fast‐responding thermometer and radio refractometer in convective conditions over a flat surface have been studied. Warm, moist ascending patches of air emerging from a layer of mechanical turbulence near the surface were observed up to about 600 m. The excess temperature of these patches decreased rapidly with height. Between 1,000 m and cloud base (1,300 m) there was evidence of warm dry air descending from above cloud base. This could make a significant contribution to the warming in the convective layer.
