  abstract = {{T}he  oceans  have  a  profound  influence  on  the  weather  and  climate  of  {S}outh  {A}frica.  {N}ot  only,  most  rainfall comes from condensation of water vapor originating from the flux of moisture from ocean to atmosphere but the temperature of the remote and surrounding oceans have an impact of the interannual variability of rainfall. {A} good example of this remote effect is the impact of the ocean during {E}l {N}ino when the temperature of the {P}acific and {I}ndian {O}cean is higher than normal. {T}his creates more rainfall above the higher sea surface temperature thus modifying the global {W}alker and {H}adley circulation. {A}ir usually  rises  in  the  equatorial  regions,  especially  above  the  ocean  creating  rainfall  which  increases  further the ascending motion of air. {T}he air is eventually pushed poleward and then cools and sinks in the subtropical region where {S}outhern {A}frica sits, creating high pressure and subsidence which is not favorable  to  rainfall.  {T}his  is  one  of  the  teleconnection  mechanisms  linking  remote  oceanic  region  to  {S}outh {A}frica. {T}he aim of the project was to better understand the role of the ocean on weather, climate and rivers of {S}outhern {A}frica. {L}ittle work has been done to connect streamflow to the {E}l {N}ino {S}outhern {O}scillation previous to that project. {W}e also looked at the tropical {A}tlantic {O}cean, which is closer to us although  but  smaller  where  a  similar  phenomenon  to  {E}l  {N}ino  occurs,  the  {B}enguela  {N}ino. {C}loser  to  {S}outh {A}frica, the {A}gulhas {C}urrent was known to impact the atmosphere above it due to high turbulent flux of moisture from sea to atmosphere. {I}n the past, due to low resolution reanalyzed climate data that did not integrate the {A}gulhas {C}urrent, it was not possible to study the impact of the {A}gulhas {C}urrent on local climate with reanalyzed climate dataset such as {ERA} or {NCEP}.  {T}his project made some important advance to that matter using new high resolution reanalyzed climate data and a model and offer some sounds  evidence  on  the  impact  of  the  {A}gulhas  {C}urrent  on  coastal  rainfall. {A}  list  of  publication  originating directly from the project and a list of student and thesis supported by the project is found at the end of the executive summary.},
