Is climate sensitivity related to dynamical sensitivity? A Southern Hemisphere perspective
Abstract This study examines whether the spread in the climate sensitivity of CoupledModel Intercomparison Project Phase 5 (CMIP5) models also captures the spread in the Southern Hemisphere dynamical response to greenhouse gas forcing. Three metrics are proposed to quantify the “dynamical sensitivity” of the Southern Hemisphere: the poleward expansion of the Hadley circulation, the poleward exp...
متن کاملHow sensitive is climate sensitivity?
[1] Estimates of climate sensitivity are typically characterized by highly asymmetric probability density functions (pdfs). The reasons are well known, but the situation leaves open an uncomfortably large possibility that climate sensitivity might exceed 4.5°C. In the contexts of (1) global‐ mean observations of the Earth’s energy budget and (2) a global‐mean feedback analysis, we explore what ...
متن کاملSimulated ENSO Sensitivity to Climate
This chapter examines the sensitivity of tropical Pacific interannual variability to changes in the climatological background state. Chapter 5 showed that although a wide variety of climate perturbations can affect the equatorial Pacific, the equatorial structure of the response tends to be similar in each case. Due to strong coupled feedbacks like those active in ENSO, the Pacific climatology ...
متن کاملWhy is climate sensitivity so unpredictable?
Uncertainties in projections of future climate change have not lessened substantially in past decades. Both models and observations yield broad probability distributions for long-term increases in global mean temperature expected from the doubling of atmospheric carbon dioxide, with small but finite probabilities of very large increases. We show that the shape of these probability distributions...
متن کاملWhy is estimating climate sensitivity so problematical
Introduction Climate sensitivity estimates exhibit little consistency. As shown in the Introduction, Figure 1 of Box 12.2 of AR5 i (reproduced here as Figure 1) reveals that 5–95% uncertainty ranges estimated for equilibrium climate
