Abstract
Ensemble average shapes of temperatureθ and vertical velocityw associated with a ‘ramp-like’ signature of the temperature signal recorded in the marine surface layer have been obtained with the use of a conditional sampling technique. The resulting shapes support the ‘ramp-like’ description of temperature and also suggest an approximately linear distribution in the case ofw. The sharp decrease in temperature at the upwind end of the ramp coincides with a relatively sharp decrease in vertical velocity. The region of the ramp in the vicinity of the sharp temperature decrease makes a large contribution to the average heat flux in the layer.
