PhD student Chris Cardinale leads this new paper “Stratospheric and Tropospheric Flux Contributions to the Polar Cap Energy Budgets”, now accepted in Journal of Climate.
In this, Chris’s first peer-reviewed publication, we look at the detailed temporal and vertical structure of the poleward fluxes of moist static energy using the NASA-MERRA-2 reanalysis. We are interested in separating the effects of stratospheric and tropospheric circulations on the total poleward energy transport, as well as the differing impacts of these circulations on the energy budget of the polar regions.

Brian’s latest paper (with colleagues Tim Cronin from MIT and Cecilia Bitz from UW) is called “Ice Caps and Ice Belts: the effects of obliquity on ice-albedo feedback”. It has been accepted for publication in the Astrophysical Journal. The paper looks at the basic rules governing planetary ice extent on Earth-like exoplanets at different obliquities. Click here for a preprint of the accepted manuscript.
Obliquity is the angle of a planet’s axis of rotation relative to its orbital plane. On Earth that angle is about 23.5º, and among other things, is the reason we have seasons. Something funny happens for planets at obliquity angles exceeding 55º. When you average over a whole year, the total amount of sunlight is largest at the poles and smallest at the equator.

The paper is Rose and Rayborn, “The effects of ocean heat uptake on transient climate sensitivity”. It deals with the phenomenon of time-dependent climate sensitivity, and explores some compelling new ideas about connections between the oceans, atmospheric radiation, and global cloud cover that determine climate sensitivity. Our paper includes substantial review as well as some interesting original results and speculations.

Our latest paper: The vertical structure of tropospheric water vapor: comparing radiative and ocean-driven climate changes, by Rose and Rencurrel, is in press for Journal of Climate. See previous post for a description. The preprint is now available online from my publication page, or directly from Journal of Climate.

Our latest paper: The vertical structure of tropospheric water vapor: comparing radiative and ocean-driven climate changes, by Rose and Rencurrel, is now accepted for publication in Journal of Climate.
The paper looks at rates of change of precipitable water with surface temperature in a suite of simulations driven by different combinations of greenhouse gas forcing and prescribed ocean heat uptake. We find fractional rates ranging between 3.6 and 11 %/K globally. These results seem at first glance to suggest substantial departures from Clausius-Clapeyron scaling, but actually result from different spatial patterns of temperature change and nearly fixed relative humidity.
