Two-dimensional reconstruction of past sea level (1950–2003) from tide gauge data and an Ocean General Circulation Model
past sea level Ocean General Circulation Model Two-dimensional
2009/12/3
A two-dimensional reconstruction of past sea level is proposed at yearly interval over the period 1950–2003 using tide gauge records from 99 selected sites and 44-year long (1960–2003) 2°×2° sea level...
Response of an ocean-atmosphere climate model to Milankovic forcing
ocean-atmosphere climate model Milankovic forcing
2009/11/16
There is considerable evidence in support of Milankovic's theory that variations in high-latitude summer insolation caused by Earth orbital variations are the cause of the Pleistocene ice cycles. The ...
