The thermodynamic structure of boundary la)l:r over Calcutta on the eastern secto r of the monsoon
trough has been exam ined byint~ratina I one-dimensional TKE closure planetary bound ary laye r model for
tropics which inJcudes interaction oCclo udiness and radiation with turbulence and counter , radient transports of
heal moistu re and momentum. Data sets cf pilct-esperiment phase ofMONTBLEX in 1988 have been used formis
purpo se. two specific situations, o ne 'When liquid water is present and the other ~tlcn very strona: winds are prevailina
in the boundary layer 8~ considered. Diurn al varialion oCturbulent kinetic ener'ly.lhe TKE budget and the veelical
profiles otTKE and eddy exchange coefficient ha ve revealed the importance DC counter gradient transports not
only aCheat and moisture but also oC momentum. Combined role DC presence of liquid water and counter gradients
in buoyant production and role of counter a:radienu of momentum in shear production have been
established.
