The greater increases in erosion in the GGa1 scenario was attributed to greater variability in monthly precipitation and an increased frequency of large
storms in the model simulation.

Dr Stephen Grimes of Plymouth University, who initiated the research project, highlighted the climate changes that must have caused this increase
in sediment erosion and transport — «We have climate
model simulations of the effect of warming on rainfall during the PETM event, and they show some changes
in the average amounts of rainfall, but the largest change is how this rainfall is packaged up — it's concentrated
in more rapid, extreme events — larger and bigger
storms.»
Using computer
models and
simulations, the team found an increase
in the average intensity during the period and the
storms most often moved into higher latitudes — to a more northward direction.
In the simulations that included smoke - filled air, storm clouds were lower and thicker (and average wind speeds at 1 kilometer above ground were higher) than they were in the no - smoke models, the team reported online ahead of print in Geophysical Research Letter

It's not just the observational systems, but also the fact that we often can identicfy
in weather forecasts (
model simulations) conditions that are favourale for such
storms, so that we know
in advance when too keep a watchful eye.
Additionally, changes
in anthropogenic sulfate aerosol forcing have been proposed as the dominant cause of the AMV and the historical multidecadal variations
in Atlantic tropical
storm frequency, based on some
model simulations including aerosol indirect effects.
Fan is also looking at how severe
storms and these physical impacts can be represented
in earth system
model simulations.
The issue of how much credibility the global
models have
in their
simulations of the spatial structure of the trends
in ocean surface temperatures is likely to be a central issue when assessing the credibility of projections of future tropical
storm activity.
