Abstract The polar region has been one of the fastest warming places on Earth in response to greenhouse gas (GHG) forcing. Two distinct processes contribute observed signal: (i) local direct GHG forcing and (ii) effect enhanced poleward heat transport from low latitudes. A series aquaplanet experiments, which excludes surface albedo feedback, is conducted quantify relative contributions these two physical magnitude degree amplification global mean. globe divided into zonal bands with equal...
Abstract This study examines the effects of vertical structure polar warming on remote atmospheric circulation. We apply thermal forcing at different levels in Northern Hemisphere region two global climate models complexity, both coupled to an aquaplanet slab ocean. The efficacy heating perturbing increases with altitude which it is applied. robust sensitivity arises from dominance surface temperature contribution outgoing longwave radiation owing large emissivity troposphere. An upper‐level...
Abstract The Hadley cell response to globally increasing CO 2 concentrations is spatially complex, with an intensified rising branch and weakened descending branch. To better understand these changes, we examine the sensitivity of idealized radiative forcing in different latitude bands. is, first order, governed by latitudinal structure forcing. strengthening upward attributed tropical forcing, whereas weakening extratropical These direct radiatively-forced responses are amplified changes...
The mechanism of polar amplification in the absence surface albedo feedback is investigated using an atmospheric model coupled to aquaplanet slab ocean forced by a CO 2 doubling. In particular, we examine sensitivity warming response under different insolation conditions from equinox (EQN) annual mean (ANN) seasonally varying (SEA). Varying greatly affects climatological static stability. condition, with largest stability, exhibits bottom-heavy vertical profile that leads strongest...
Chronic pain is associated with alterations in fundamental cellular processes. Here, we investigate whether Beclin 1, a protein essential for initiating the process of autophagy, involved processing and targetable relief. We find that monoallelic deletion Becn1 increases inflammation-induced mechanical hypersensitivity male mice. However, females, loss does not affect hypersensitivity. In males, intrathecal delivery 1 activator, tat-beclin reverses inflammation- nerve injury-induced prevents...
Abstract The shortwave cloud radiative effect (SWCRE) is important for the Arctic surface radiation budget and a major source of inter‐model spread in simulating climate. To better understand individual contributions various processes to changes SWCRE, we extend existing Approximate Partial Radiative Perturbation (APRP) method by adding absorptivity upward beam, considering differences reflectivity between downward beams, analyzing masking resulting from albedo. Using data CMIP model...
