Cross-Cutting Topic: Decadal Prediction
There are many examples of extreme climate variations on decadal timescales, many of which are associated with human death and misery. Perhaps the most striking in recent decades is the decadal timescale drought in the Sahel (leading, for example, to the remarkable Band-Aid Concerts). Other decadal-timescale droughts, such as the “dust-bowl” drought in the Southern US in the 1930s, are infamous...
متن کاملDecadal climate prediction (project GCEP).
Decadal prediction uses climate models forced by changing greenhouse gases, as in the International Panel for Climate Change, but unlike longer range predictions they also require initialization with observations of the current climate. In particular, the upper-ocean heat content and circulation have a critical influence. Decadal prediction is still in its infancy and there is an urgent need to...
متن کاملDecadal Climate Predictability and Prediction
What: Forty-five researchers met to discuss strategies to better understand and predict decadal climate variability. When: 12–15 October 2009 Where: St. Michaels, Maryland T he importance of decadal climate variability (DCV) research is being increasingly recognized, including by the World Climate Research Program (WCRP) and the Intergovernmental Panel on Climate Change (IPCC). An improved unde...
متن کاملDecadal Variability in ENSO Predictability and Prediction
A simple coupled model is used to examine decadal variations in El Niño–Southern Oscillation (ENSO) prediction skill and predictability. Without any external forcing, the coupled model produces regular ENSO-like variability with a 5-yr period. Superimposed on the 5-yr oscillation is a relatively weak decadal amplitude modulation with a 20-yr period. External uncoupled atmospheric ‘‘weather nois...
متن کاملTropical Atlantic Biases in CCSM4
This paper focuses on diagnosing biases in the seasonal climate of the tropical Atlantic in the twentiethcentury simulation of the Community Climate System Model, version 4 (CCSM4). The biases appear in both atmospheric and oceanic components. Mean sea level pressure is erroneously high by a few millibars in the subtropical highs and erroneously low in the polar lows (similar to CCSM3). As a re...
