Impact of hindcast length on estimates of seasonal climate

Mar 16 2015It has recently been argued that single-model seasonal forecast ensembles are overdispersive implying that the real world is more predictable than indicated by estimates of so-called perfect model predictability particularly over the North Atlantic

North Atlantic climate far more predictable following

North Atlantic Oscillation) are highly predictable enabling advanced warning of whether winters in the coming decade are likely to be stormy warm and wet or calm cold and dry However the study revealed that this predictable signal is much smaller than it should be in current climate models

Predictability of North Atlantic Multidecadal Climate

Atmospheric weather systems become unpredictable beyond a few weeks but climate variations can be predictable over much longer periods because of the coupling of the ocean and atmosphere With the use of a global coupled ocean-atmosphere model it is shown that the North Atlantic may have climatic predictability on the order of a decade or longer

Is AMOC More Predictable than North Atlantic Heat Content

Another indication that AMOC may be less predictable than heat content is seen if we consider power spectra of intrinsic AMOC and North Atlantic heat content fluctuations in various climate models As described in more detail in section 2 if one plots a nine-model average of such spectra ( Fig 1 top) it is heat content that is much redder

Climate Change

Aug 20 2012Climate is potentially predictable for much longer time scales than weather for several reasons One reason is that climate can be meaningfully characterized by seasonal-to-decadal averages and other statistical measures and the averaged weather is more predictable than

Hidden predictability in winds could improve climate forecasts

So far more than 70 countries that plan to finance their own vaccine have fice to predict changes in the North Atlantic Hidden predictability in winds could improve climate forecasts more predictable than models capture by an order of magnitude Smith says It also sug-

Study introduces new model processing technique shows

Climate model projections can be hindered by complexities inherent in the climate system and difficulty in detecting the part of the forecast that can be accurately predicted (signals) as well as constraining uncertainties (noise) These problems can be hard to fix as climate model projections cannot be verified until there are observations A Climate Variability and Predictability (CVP

North Atlantic oscillation

The North Atlantic Oscillation (NAO) is a weather phenomenon in the North Atlantic Ocean of fluctuations in the difference of atmospheric pressure at sea level (SLP) between the Icelandic Low and the Azores High Through fluctuations in the strength of the Icelandic low and the Azores high it controls the strength and direction of westerly winds and location of storm tracks across the North

Is AMOC More Predictable than North Atlantic Heat Content

For the most predictable of these patterns AMOC retains predictability for more than two decades in a typical model These patterns are associated with heat content fluctuations that also have above-average predictability which suggests that AMOC may have a positive influence on the predictability of heat content for these special structures

North Atlantic climate far more predictable following

Jul 30 2020The headline: "North Atlantic climate far more predictable than models imply" nails it They find that the NAO has a low frequency signal part which models don't replicate see fig 2a They deduce that CMIP5's and 6's do not show the climate of the real world when it

Is AMOC More Predictable than North Atlantic Heat Content

For eight of the models this range is less than the corresponding range for heat content For 5- and 10-yr averages predictability is substantially greater than for annual means for both fields but the enhancement is more for AMOC indeed for the averaged fields AMOC is more predictable than

Skillful long‐range prediction of European and North

1 Introduction Despite recent advances in weather and climate forecasting skillful predictions of year to year fluctuations in winter North Atlantic Oscillation [Walker and Bliss 1932] and associated changes in weather at lead times of months have until recently been elusive [Johansson 2007 Kim et al 2012 Smith et al 2012] This is because climate models have shown little
