Results
These pages contain results from statistical downscaling for various geographical locations (stations)
in Norway. The data are taken from the following sources:
- Prediction of local monthly precipitation during the period 1870-2050 based on
the 2m temperature and the SLP field from the ECHAM4/OPYC3 GSDIO integration (which
includes effects of greenhouse-gases and tropospheric ozon, as well as direct and indirect effects of
sulphur aeroseols).
- Prediction of local monthly mean temperature during the period 1870-2050, also based on the 2m temperature
field from the ECHAM4/OPYC3 GSDIO integration.
The model results from dynamical downscaling is presented throught graphical maps for selected
surface weather parameters. The data from the computational grid of the regional climate model have
been made available for downloading in ascii-format for a selected geographical area covering
the Nordic countries.
Presently, the model results are described in:

Response in daily precipitation and wind speed extremes from
HIRHAM downscaling of SRES B2 scenarios, by J. E. Haugen and T. Iversen
Results from Dynamical downscaling is presented here through
a graphical interface
that makes it possible to select stations in Norway.
Presently the data is based on selections from the reports:

Refinement of dynamically downscaled precipitation and
temperature scenarios by Torill Engen-Skaugen.
Abstract:
A method for adjusting dynamically downscaled precipitation and
temperature scenarios representing specific sites is presented.
The method reproduces mean monthly values and standard deviations
based on daily observations. The trend obtained in the regional
climate model both for temperature and precipitation is maintained,
and the frequency of modelled and observed rainy days shows better
agreement. Thus, the method is appropriate for tailoring
dynamically downscaled temperature and precipitation values for
climate change impact studies. One precipitation and temperature
scenario dynamically downscaled with HIRHAM from the
Atmospheric-Ocean General Circulation Model at the Max-Planck
Institute in Hamburg, ECHAM4/OPYC4 GSDIO with emission scenario
IS92a, is chosen to illustrate the adjustment method.
