North Atlantic Oscillation

NAO signal

experiments with a global climate model

Data Analysis

Climate variability

• Air-sea interaction
  • Large scale
  • Upwelling
  • Sea ice
• Air-land interaction
  • Snow
• Local responses

Climate predictability

• Linear model

• Analog technique

Atmospheric general circulation model (AGCM)

• the cycle 5.3 version from the Laboratoire de Météorologie Dynamique (LMD), Paris.

• 96x72 in longitude and latitude

• 15 vertical levels

Oceanic general circulation model (OGCM)

• OPA 7 from the Laboratoire de Oceanologie Dynamique et Climatologie (LODYC), Paris.

• 182x152 in longitude and latitude

• 30 vertical levels

Coupled with OASIS developed at CERFACS, Toulouse. The frequency of comunication between AGCM and OGCM is daily.
