Convective Structures of the Near-Surface Air Layer

Changes in pulsation components of air temperature at altitudes of up to 1 m over a surface heated to 30°–55°C under convective conditions at moderate (2010) and high (2011) wind velocities in deserted sandy areas are studied. Synchronized measurements were made at six levels: 3, 6, 12, 25, 50, and 100 cm. Temporal changes in convective structures with allowance for the “turbulence embeddedness” hypothesis actually reflect their movement under the influence of wind. The shape and size of convective structures and statistical characteristics reflected in the spectral functions change at different velocities.
