¥The atmosphere
is like a falling Kleenex!
¥The uncertainty in the initial conditions grow during the evolution of a weather
forecast.
¥ So
a point forecast made for a long time will ultimately be worthless, no better than a
guess!
¥There is a limited amount of predictability,
but only for a short
period of time.
¥ Loss
of predictability is an attribute of nature. It is not
an artifact of computer models.
