Atmospheric Mixed Layer Convergence from Observed MJO Sea Surface Temperature Anomalies

Simulations of the Atmospheric Response to South Atlantic Sea Surface Temperature Anomalies

The sensitivity of the atmospheric circulation to sea surface temperature (SST) anomalies over the tropical and subtropical South Atlantic is studied by means of simulations with an atmospheric general circulation model (GCM). Two cases are considered depending upon the prescribed SST anomalies. The first is observed to occur during austral summers in association with a strengthening of the Sou...

Sea Surface Temperature Anomalies: A Possible Trigger for ENSO

Simultaneous Tuning of Water Vapour and Atmospheric Temperature for Determination of Sea Surface Temperature from AVHRR

A novel physics-based method for determination of sea surface temperature (SST) from AVHRR is explained in detail. Starting from the equation of radiative transfer in the mean value approximation, we use variational calculus to derive an expression relating the difference between the radiance calculated using a first guess atmospheric profile and the observed satellite radiance (∆I), to the cor...

In Situ Observations of Madden–Julian Oscillation Mixed Layer Dynamics in the Indian and Western Pacific Oceans

The boreal winter response of the ocean mixed layer to the Madden–Julian oscillation (MJO) in the IndoPacific region is determined using in situ observations from the Argo profiling float dataset. Composite averages over numerous events reveal that the MJO forces systematic variations in mixed layer depth and temperature throughout the domain. Strong MJO mixed layer depth anomalies (.15 m peak ...

Processes that influence sea surface temperature and ocean mixed layer depth variability in a coupled model

A 50-year coupled atmosphere-ocean model integration is used to study sea surface temperature (SST) and mixed layer depth (h), and the processes which influence them. The model consists of an atmospheric general circulation model coupled to an ocean mixed layer model in ice-free regions. The midlatitude SST variability is simulated fairly well, although the maximum variance is underestimated an...
