Decadal Predictability of the Atlantic Ocean in a Coupled GCM: Forecast Skill and Optimal Perturbations Using Linear Inverse Modeling
Publisher: American Meteorological Society
Abstract: The decadal predictability of three-dimensional Atlantic Ocean anomalies is examined in a coupled global climate model [the third climate configuration of the Met Office Unified Model (HadCM3)] using a linear inverse ...
Connecting Climate Model Projections of Global Temperature Change with the Real World
Publisher: American Meteorological Society
Abstract: urrent state-of-the-art global climate models produce different values for Earth?s mean temperature. When comparing simulations with each other and with observations, it is standard practice to compare temperature anomalies ...
The Potential to Narrow Uncertainty in Regional Climate Predictions
Publisher: American Meteorological Society
Abstract: Faced by the realities of a changing climate, decision makers in a wide variety of organizations are increasingly seeking quantitative predictions of regional and local climate. An important issue for these decision makers, ...
Estimating Climatically Relevant Singular Vectors for Decadal Predictions of the Atlantic Ocean
Publisher: American Meteorological Society
Abstract: A key aspect in designing an efficient decadal prediction system is ensuring that the uncertainty in the ocean initial conditions is sampled optimally. Here one strategy for addressing this issue is considered by investigating ...
The Climate Spiral Demonstrates the Power of Sharing Creative Ideas
Publisher: American Meteorological Society
Abstract: AbstractGraphical visualizations have the potential to engage diverse audiences in understanding the changes to our climate, especially when spread worldwide using both traditional and social media. The animated global ...
Atmospheric and Oceanic Contributions to Irreducible Forecast Uncertainty of Arctic Surface Climate
Publisher: American Meteorological Society
Abstract: ncertainty of Arctic seasonal to interannual predictions arising from model errors and initial state uncertainty has been widely discussed in the literature, whereas the irreducible forecast uncertainty (IFU) arising from ...
The Interpretation and Use of Biases in Decadal Climate Predictions
Publisher: American Meteorological Society
Abstract: ecadal climate predictions exhibit large biases, which are often subtracted and forgotten. However, understanding the causes of bias is essential to guide efforts to improve prediction systems, and may offer additional ...
Robust Future Changes in Temperature Variability under Greenhouse Gas Forcing and the Relationship with Thermal Advection
Publisher: American Meteorological Society
Abstract: ecent temperature extremes have highlighted the importance of assessing projected changes in the variability of temperature as well as the mean. A large fraction of present-day temperature variance is associated with thermal ...
