Sensitivity of polar amplification to varying insolation conditions
Journal of Climate, 2018 The mechanism of polar amplification in the absence of surface albedo feedback is investigated using an atmospheric model coupled to an aquaplanet slab ocean forced by a CO2 doubling.

Idealized models of Polar Amplification
, 2021 To study polar amplification (PA), two idealized energy balance models are constructed: a dry-diffusive down-gradient model (diffusion model) and a model where horizontal heat fluxes are configured in such a way as to maximize entropy production (MEP ...

Heterogeneous Polar Amplification
Arctic and Antarctic climate evolution is crucial for understanding global climate dynamics. This study grounds in the framework of Gadea and Gonzalo (2020, 2025) to analyze different distributional characteristics (beyond the average) of polar ...

Energy transport, polar amplification, and ITCZ shifts in the GeoMIP G1 ensemble [PDF]
Atmospheric Chemistry and Physics, 2018 The polar amplification of warming and the ability of the Intertropical Convergence Zone (ITCZ) to shift to the north or south are two very important problems in climate science.

Arctic amplification: does it impact the polar jet stream?
Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 It has been hypothesised that the Arctic amplification of temperature changes causes a decrease in the northward temperature gradient in the troposphere, thereby enhancing the oscillation of planetary waves leading to extreme weather in mid-latitudes. To

The polar amplification asymmetry: role of Antarctic surface height [PDF]
Earth System Dynamics, 2017 . Previous studies have attributed an overall weaker (or slower) polar amplification in Antarctica compared to the Arctic to a weaker Antarctic surface albedo feedback and also to more efficient ocean heat uptake in the Southern Ocean in combination with

Polar amplification of orbital-scale climate variability in the early Eocene greenhouse world [PDF]
Climate of the PastClimate variability is typically amplified towards polar regions. The underlying causes, notably albedo and humidity changes, are challenging to accurately quantify with observations or models, thus hampering projections of future polar amplification ...

Polar Amplification: A Fractional Integration Analysis
SSRN Electronic JournalThis paper uses fractional integration methods to obtain new evidence on polar amplification. The adopted modelling framework is very general since it allows the differencing parameter to take any real value, including fractional ones, and provides ...
