The diurnal nature of future extreme precipitation intensification [PDF]
, 2019 Short‐duration, high‐impact precipitation events in the extratropics are invariably convective in nature, typically occur during the summer, and are projected to intensify under climate change.

Thermodynamic cycles in the stratosphere [PDF]
Journal of the Atmospheric Sciences, 2020 <p>Large-scale overturning mass transport in the stratosphere is commonly explained through the action of potential vorticity (PV) rearrangement in the flank of the stratospheric jet. Large-scale Rossby waves, with their wave activity source primarily in the troposphere, stir and mix PV and an overturning circulation arises to compensate ...

A dynamic model for the optimization of oscillatory low grade heat engines [PDF]
, 2011 The efficiency of a thermodynamic system is a key quantity on which its usefulness and wider application relies. This is especially true for a device that operates with marginal energy sources and close to ambient temperatures.

Advances in understanding large-scale responses of the water cycle to climate change [PDF]
, 2020 Globally, thermodynamics explains an increase in atmospheric water vapor with warming of around 7%/°C near to the surface. In contrast, global precipitation and evaporation are constrained by the Earth's energy balance to increase at ∼2–3%/°C.
