A 21st century projection under SRES A1B scenario initialized in the year of the 20C_3. (EH5-T63L31_OM-GR1.5L40_A1B_3)

Model:ECHM5 The atmospheric GCM ECHM5 has a spectral drnamical core where vorticity, divergence, temperature and surface pressure are represented in the horizontal by a truncated series of harmonics. A semi-Lanrangian scheme is used for the transport of water components (water vapour, cloud liquid water and cloud ice)

Scenario: A1B SRES A1B seems to be the most plausible scenario, describes a future world rapid economic growth, a global population that peaks in mid-century and declines thereafter, and increase cultural and social interactions. The technological emphasis of this scenario is on a balance across all energy sources, not relying too heavily on any particular energy source.
