In a typically hilarious goodbye video by Commander Zorg, we get to enjoy their
weather predictions of «bleak» and «bleaker still» before finishing off
with the all - too - familiar (to those of you as old as I am) BBC testcard image, except the only clown on screen is a certain PDM OBE.
We know that when James Hansen made his famous
predictions to congress in 1988 that he didn't know he was comparing a period, which was in the warm end of a sixty year PDO
weather cycle
with periods in the cool end.
The researchers compared
predictions of 22 widely used climate «models» — elaborate schematics that try to forecast how the global
weather system will behave —
with actual readings gathered by surface stations,
weather balloons and orbiting satellites over the past three decades.
Specific examples of additional impacts include a reduction in capital equipment acquisitions across the entire lab
with computing alone sliding from $ 7 million to $ 3 million, the elimination of NCAR's lidar research facility as well as the extra-solar planet program, delays in computer modeling and
prediction efforts for both
weather and climate, reductions in the solar coronal observing program, a reduction in the number of post doctoral appointments, reduction of the societal impacts program, and widespread deferred maintenance and delays in equipment and instrument acquisition and replacement.
For
weather predictions, accuracy disappears within a few weeks — but for ocean forecasts, accuracy seems to have decadal scale accuracy — and when you go to climate forcing effects, the timescale moves toward centuries,
with the big uncertainties being ice sheet dynamics, changes in ocean circulation and the biosphere response.
Axel Schweiger wrote, that we had just a couple of warm springs, which caused the deviation from the GCM
predictions, and this is one interesting point: Is this «couple o» warm springs» really something coming and going like any cyclone, or is it a sign of a changing
weather regime
with stronger mixing and stronger heat transport?
This claim is complemented
with a broad literature synthesis of past work in numerical
weather prediction, observations, dynamical theory, and modeling in the central U.S. Importantly, the discussion also distills some notoriously confusing aspects of the super-parameterization approach into clear language and diagrams, which are a constructive contribution to the literature.
On the off chance you actually are interested in evidence, I would suggest reading about the (very different) methods of
prediction that are used for
