The Atmosphere and Ocean – A Physical Introduction 3e

Dr Neil Wells is a lecturer in the Oceanography department at Southampton University in ocean modeling, climate and sea air interaction. Research in, large scale ocean modelling with interests in heat fluxes and heat content change. (ii) Application of ARGO data sets to determine ocean heat content change. (iii) Links of above with air-sea interaction from seasonal to decadal change. (iv) Storm surges and tidal interaction in coastal seas and relationship to climate change.
