Storm-Track Upper Ocean Interaction and the Impact on European Climate

Objective



Objectives :

To improve the understanding of the nature of the
N.Atlantic winter storm-track,
the causes of its variability and the influence on
European climate of this variability.



Brief Description of the Research Project :


The weather systems in the N.Atlantic tend to occur in a
longitudinally extended region referred to as a storm-track. This storm-track exhibits significant
variability from one year to another and from one decade
to another. The weather and, in particular extremes in
this weather, over Europe are very dependent on the
storm-track.

The prediction of storm-track behaviour is probably the
greatest goal of seasonal prediction for the European
region. Any changes in storm-track behaviour would be
probably the most important anthropogenic climate change
for Europe.

The surface wind and net transfers of heat and water
drive the N.Atlantic Ocean so that changes in the storm-track affect the ocean. Conversely it is thought that
changes in the sea surface temperature influence the
storm-track.

In this project increased understanding of these
processes and their predictability will be sought through
a programme involving sophisticated diagnosis of data
from observational analyses and of the output from a
range of numerical models. The diagnostics will be
designed to show the interannual modes of winter-time
variability in the N.Atlantic/European region, and the
relationship of the storm-track and European extreme
weather to them. They will give evidence of the
strength and nature of the influence of sea surface
temperature on the atmospheric variability,
and of the coupling between the atmosphere and ocean.

The models used will range from simpler process-study
atmospheric models,
through intermediate complexity atmospheric GCMs to full
atmospheric and coupled
atmosphere-ocean GCMs.
