forecasts that fill the gap between medium range
weather forecasts (up to two weeks) and
seasonal forecasts (3 - 6 months).
In the context of humanitarian aid and disaster preparedness, the Red Cross Climate Centre / IRI have proposed a «Ready - Set - Go» concept for making use of
forecasts from
weather to
seasonal, in which
seasonal forecasts are used to begin monitoring of subseasonal and short - range
forecasts, update contingency plans, train volunteers, and enable early warning systems («Ready»); sub-monthly
forecasts are used to alert volunteers, warn communities («Set»); and,
weather forecasts are then used to activate volunteers, distribute instructions to communities, and evacuate if needed («Go»).
Substantial progress has been made in recent years on the development and applications of medium - range
weather forecasts and
seasonal climate predictions.
«The IRI and other centers have been issuing
seasonal climate predictions routinely since the late 1990s, but prediction on the subseasonal range — which fills the gap between
weather forecasts and
seasonal forecasts — is an emerging area of research,» Robertson told the IRI.
Mikhail Tolstykh is an expert for global numerical
weather prediction models to develop medium - range and
seasonal forecasts.
For
weather that limit seems to be about a week out, but people still sell
seasonal forecasts.
A unified treatment of
weather and climate models (i.e. the same dynamical cores for the atmosphere and ocean are used for models across the range of time scales) transfers confidence from the
weather and
seasonal climate
forecast models to the climate models used in century scale simulations.
This is why there is little faith placed in CAGW
forecasts, any one who knows anything about how the
weather really works, understands the real drivers are not even understood enough to used in models yet, and with out considering the background patterns of the
seasonal, annual, decadal trends that determine how the
weather works, are even used in
weather forecasting, in a viable active method, why should ANY confidence be placed in CAGW long range unverifiable modeled
forecasts?
This project will advance our understanding of
seasonal ice zone (SIZ) cloud - ice feedbacks and our ability to
forecast SIZ
weather and ice conditions through the combination of carefully designed model experiments, observations, and technology developments which are targeted to validate and improve the models.

Just as
weather forecasts are useful for a week or so until too many errors accumulate — it may just be possible to build a climate model that is useful for
seasonal to decadal
forecasting.
Currently, ICPAC runs WRF model for medium range
weather forecasts, PRECIS model for climate chnage and scenario development; and is in the process of setting up a Regional Spectral Model (RSM) for downscaling
