Query: Air-sea interaction in tropical atmosphere: influence of ocean mixing on
  atmospheric processes   One the major factors determining the development and evolution of
atmospheric convection is the sea surface temperature and its variability.
Results of this thesis show that state of atmospheric convection impacts the
diurnal distribution of thermal energy in the upper ocean. Under calm and clear
sky conditions a shallow warm layer of several meters depth develops on the
surface of the ocean. This warm layer drives an anomalous flux from the ocean
to the atmosphere. A novel Kelvin wave trajectory database based on satellite
data is introduced in this study. The investigation of its data shows that
substantial fraction of Kelvin waves is initiated as a result of interaction
with another Kelvin wave. Two distinct categories are defined and analyzed: the
two- and multiple Kelvin wave initiations, and a spin off initiation. Results
show that primary forcing of such waves are high diurnal cycle and/or increased
wind speed and latent heat flux at the ocean surface. Variability of the ocean
surface and subsurface along Kelvin wave trajectories over Indian Ocean is
investigated: wind speed and latent heat flux increase and a sea surface
temperature anomaly decreases during a wave passage. It is also shown that
Kelvin waves are longitude-diurnal cycle phase locked over the Maritime
Continent. This cycle phase locking is such that it agrees with mean, local
diurnal cycle of convection in the atmosphere. The strength of the
longitude-diurnal cycle phase locking differs between non-blocked Kelvin waves,
which make successful transition over the Maritime Continent, and blocked waves
that terminate within it. The distance between the islands of Sumatra and
Borneo agrees with the distance travelled by an average Kelvin wave in one day.
This suggests that the Maritime Continent may act as a filter, favoring
successful propagation waves, which are in phase with the local diurnal cycle
of convection.
