WP-MIP: An Artificial Intelligence, Hybrid, and Physically Based Model Intercomparison Project for Weather Prediction
Ron McTaggart-Cowan, Linus Magnusson, Inna Polichtchouk +57
Rapid progress in the field of machine-learning for weather prediction has led to the emergence of algorithms whose forecasting skill can exceed that of traditional physically base…
Machine learning emulation of gravity wave drag in numerical weather forecasting
Matthew Chantry, Sam Hatfield, Peter Duben +2
We assess the value of machine learning as an accelerator for the parameterisation schemes of operational weather forecasting systems, specifically the parameterisation of non-orog…
Zonal-mean circulation response to reduced air-sea momentum roughness
I. Polichtchouk, T. G. Shepherd
The impact of uncertainties in surface layer physics on the atmospheric general circulation is comparatively unexplored. Here the sensitivity of the zonal-mean circulation to reduc…
Equatorial superrotation in Held & Suarez-like flows with weak equator-to-pole surface temperature gradient
Inna Polichtchouk, James Y-K. Cho
Equatorial superrotation under zonally-symmetric thermal forcing is investigated in a setup close to that of the classic Held & Suarez (1994) setup. In contrast to the behaviour in…
Sensitivity and Variability Redux in Hot-Jupiter Flow Simulations
J. Y-K. Cho, I. Polichtchouk, H. Th. Thrastarson
We revisit the issue of sensitivity to initial flow and intrinsic variability in hot-Jupiter atmospheric flow simulations, originally investigated by Cho et al. (2008) and Thrastar…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
Intercomparison of General Circulation Models for Hot Extrasolar Planets
Inna Polichtchouk, James Y-K. Cho, Chris Watkins +3
We compare five general circulation models (GCMs) which have been recently used to study hot extrasolar planet atmospheres (BOB, CAM, IGCM, MITgcm, and PEQMOD), under three test ca…
Baroclinic Instability on Hot Extrasolar Planets
Inna Polichtchouk, James Y-K. Cho
We investigate baroclinic instability in flow conditions relevant to hot extrasolar planets. The instability is important for transporting and mixing heat, as well as for influenci…
Methane in the atmosphere of the transiting hot Neptune GJ436b?
J. -P. Beaulieu, G. Tinetti, D. M. Kipping +14
We present an analysis of seven primary transit observations of the hot Neptune GJ436b at 3.6, 4.5 and m obtained with the Infrared Array Camera (IRAC) on the Spitzer Space Te…
