Influence of different convection parameterisations in a GCM
different convection parameterisations GCM
2009/1/21
In global models of the atmosphere convection is parameterised, since the typical scale of this process is smaller than the model resolution. Here we address some of the uncertainties arising from the...
A chemistry-transport model simulation of middle atmospheric ozone from 1980 to 2019 using coupled chemistry GCM winds and temperatures
chemistry-transport model middle atmospheric ozone GCM winds
2008/12/9
A global 40-year simulation from 1980 to 2019 was performed with the FinROSE chemistry-transport model based on the use of coupled chemistry GCM-data. The main focus of our analysis is on climatologic...
