A 21st century projection under SRES A2 scenario initialized in the year of the 20C_2. (EH5-T63L31_OM-GR1.5L40_A2_2)

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 A2 The scenario SRES A2 envisions a very heterogeneous world. The underlying theme of this scenario is self-reliance and preservation of local identities. Fertility patterns across regions of the world converge very slowly, resulting in continuously increasing world population. Economic development is primarily regionally regionally oriented and slower than in other scenario.
