  abstract = {{Fundamental puzzles of climate science remain unsolved because of our
limited understanding of how clouds, circulation and climate interact.
One example is our inability to provide robust assessments of future
global and regional climate changes. However, ongoing advances in our
capacity to observe, simulate and conceptualize the climate system now
make it possible to fill gaps in our knowledge. We argue that progress
can be accelerated by focusing research on a handful of important
scientific questions that have become tractable as a result of recent
advances. We propose four such questions below; they involve
understanding the role of cloud feedbacks and convective organization in
climate, and the factors that control the position, the strength and the
variability of the tropical rain belts and the extratropical storm

  keywords = {Climate change, Climate models, Cloud radiative effect, Aquaplanet, Tropospheric adjustment, Climate feedbacks},
  year = 2015,

  volume = 44,
  pages = {1957-1977},
  abstract = {{Idealized climate change experiments using fixed sea-surface temperature
are investigated to determine whether zonally symmetric aquaplanet
configurations are useful for understanding climate feedbacks in more
realistic configurations. The aquaplanets capture many of the robust
responses of the large-scale circulation and hydrologic cycle to both
warming the sea-surface temperature and quadrupling atmospheric
CO$_{2}$. The cloud response to both perturbations varies across
models in both Earth-like and aquaplanet configurations, and this spread
arises primarily from regions of large-scale subsidence. Most models
produce a consistent cloud change across the subsidence regimes, and the
feedback in trade-wind cumulus regions dominates the tropical response.
It is shown that these trade-wind regions have similar cloud feedback in
Earth-like and aquaplanet warming experiments. The tropical average
cloud feedback of the Earth-like experiment is captured by five of eight
aquaplanets, and the three outliers are investigated to understand the
discrepancy. In two models, the discrepancy is due to warming induced
dissipation of stratocumulus decks in the Earth-like configuration which
are not represented in the aquaplanet. One model shows a circulation
response in the aquaplanet experiment accompanied by a cloud response
that differs from the Earth-like configuration. Quadrupling atmospheric
CO$_{2}$ in aquaplanets produces slightly greater adjusted forcing
than in Earth-like configurations, showing that land-surface effects
dampen the adjusted forcing. The analysis demonstrates how aquaplanets,
as part of a model hierarchy, help elucidate robust aspects of climate
change and develop understanding of the processes underlying them.

  title = {{The diurnal cycle of marine cloud feedback in climate models}},
  journal = {Climate Dynamics},
  keywords = {Diurnal cycle, Cloud feedback, Climate change},
  year = 2015,
  month = mar,
  volume = 44,
  pages = {1419-1436},
  abstract = {{We examine the diurnal cycle of marine cloud feedback using high
frequency outputs in CFMIP-2 idealised uniform +4 K SST perturbation
experiments from seven CMIP5 models. Most of the inter-model spread in
the diurnal mean marine shortwave cloud feedback can be explained by low
cloud responses, although these do not explain the model responses at
the neutral/weakly negative end of the feedback range, where changes in
mid and high level cloud properties are more important. All of the
models show reductions in marine low cloud fraction in the warmer
climate, and these are in almost all cases largest in the mornings when
more cloud is present in the control simulations. This results in
shortwave cloud feedbacks being slightly stronger and having the largest
inter-model spread at this time of day. The diurnal amplitudes of the
responses of marine cloud properties to the warming climate are however
small compared to the inter-model differences in their diurnally meaned
responses. This indicates that the diurnal cycle of cloud feedback is
not strongly relevant to understanding inter-model spread in overall
cloud feedback and climate sensitivity. A number of unusual behaviours
in individual models are highlighted for future investigation.
